IKImageBrowserView crash
I'm using an IKImageBrowserView to show sets of PDF documents in my program and am occasionally seeing crashes during IKImageWrapper finalize calls. The crash log shows absolutely none of my code at all. This typically happens when someone is adding a document to the image browser's datasource. Has anyone seen these types of crashes and have any idea if there's a way for me to resolve it? Thanks, Ashley Here's a few relevant bits from the crash log: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x1d05e0b0 Crashed Thread: 0 Application Specific Information: objc[6119]: garbage collection is ON IKImageWrapper Thread 0 Crashed: 0 GLEngine0x1e4daf17 glDeleteTextures_Exec + 23 1 libGL.dylib 0x941cc476 glDeleteTextures + 38 2 com.apple.imageKit 0x93aa4684 _deleteTextureForIKGLImageInfo + 105 3 com.apple.imageKit 0x93aa46da _removeOwners + 53 4 com.apple.CoreFoundation0x942bcb29 CFDictionaryApplyFunction + 169 5 com.apple.imageKit 0x93aa528a - [IKGLSharedContextRegistry removeOwner:] + 141 6 com.apple.CoreFoundation0x9436ba3d __invoking___ + 29 ...

Customizing IKImageBrowserView
Hi, We are developing a project in which we have a view showing matrix of images ( a common theme). As an enhancement, we would like to support some animations while performing operations like adding, removing, reloading images to this view . As an example we could consider Apple's Preview 4.0. Though we might have to change our existing implementation to some extent, we think switching to IKImageBrowserView is a good option. With this change we can support most of the animations mentioned above. However there are a few things where we think we might run into trouble. 1. We need to customize the selection of the item as in iTunes. 2. We might in the future customize the individual thumbnails. 3. Editing title of the thumbnail. Considering the above 3 requirements we found that IKImageBrowserView is not so flexible. We think it is not possible for us to customize individual images. We tried by overriding drawrect : of IKImageBrowserView. However, we discovered that if drawrect : is overridden in IKImageBrowserView, it displays nothing. So our question boils down to the following: 1. Are we right in our approach of using IKImageBrowserView? 2. If so, how could be achieve the above requirements by leveraging IKImageBrowserView? 2a. Please let us know if there is any workaround for customizing individual images in IKImageBrowserView. 2b. Is there a method to edit text displayed in IKImageBrowserView by clicking on the text area.

IKImageBrowserView is bonkers
So I have an IKImageBrowserView in my window. It's supplied by a IKImageBrowserViewDataSource object. The images are captured from a digital camera, which is oriented in a portrait fashion. Once downloaded from the camera, the images are rotated (using jpegtran) to a "normal" orientation, the EXIF is edited to match (using exiftool, since jpegtran leaves the flag alone when it rotates it), and finally an icon is added to the file using this code: NSImage *preview = [[NSImage alloc] initWithContentsOfFile:filePath]]; [[NSWorkspace sharedWorkspace] setIcon:preview forFile:filePath options:0]; So the image is created from the rotated, EXIF-fixed image file. The image file displays correctly in Preview, Safari, QuickLook, and its Finder preview icon is correct also. Why come then does the IKImageBrowserView always initially show the image rotated 90° CW, and then a little while later refresh it to be correct? Sorry, not even INITIALLY, its whenever the view updates from the data source. The data source simply returns the full path to the image in the filesystem to display when requested. I've already determined that the image file itself is correct in all ways. You can see a short (~30 second) QT movie of this strange behavior in action at <http://idisk.mac.com/callipygiani/Public/RotationWTF.mov>. The movie shows several images being captured and added to the view, a couple deleted from the view, and then another captured and added. Any tips or suggestions as to what is going on would be GREATLY appreciated. I really don't want to have to write my own image browser view...

IKImageBrowserView aspect ratio
Hi, I have a lot of 4:3 ratio images I'd like to line up with IKImageBrowserView. Unfortunately, the default configuration forces all of the IKImageBrowserView cells to be square. Is there a way to set the aspect ratio of the IKImageBrowserView cells?

IKImageBrowserView Dragging outside
Hi all, I've been wondering on how to implement dragging out of the view in the IKImageBrowserView. I am pretty sure this is where I have to start: -imageBrowser:writeItemsAtIndexes:toPasteboard: but I don't have a clue what to do next. It's not a real File Promise, I just need the folder (in most cases the Desktop) dragged to and the indexes that have been dragged. The class seems to be quite different to the NSTableView in which I am using '-tableView:writeRowsWithIndexes:toPasteboard' and '- tableView:namesOfPromisedFilesDroppedAtDestination:forDraggedRowsWithIndexes :'. What's the method I am missing? Best regards & thanks. Tobias Jordan. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

IKImageBrowserView and reordering
Hello I am (with much success) using IKImageBrowserView. I have enabled reordering and implemented -imageBrowser:moveItemsAtIndexes:toIndex: in the image browsers delegate, which works very, very fine, until I put the contentView of the window in fullscreen. Everything else works fine, but I cant initiate a drag at all. Developing against 10.6 SDK.

IKImageBrowserView - multiline labels
I was wondering if anyone has used this control. I have a situation which it may be perfect for, but the three things I am not certain it is capable of is: 1. supporting in-place editing of the labels 2. supporting multi-line labels 3. using a smaller font in the labels I have tried to figure out how to get it to do these things, but have been unable. If it cannot, I intend to file bugs, but wanted to first verify these things weren't possible.

Re: IKImageBrowserView crash
I don't have a solution just a couple of suggestions. As GC is enabled you can try temporarily disabling the collector. Bracket the crashing code segment with: [[NSGarbageCollector defaultCollector] disable]; // crashing code [[NSGarbageCollector defaultCollector] enable]; Otherwise I can only suggest extracting the essentials of your code into a test project.

IKImageBrowserView Title & Subtitle Woes
Hello all. I am trying to set the color of the title and subtitle in an IKImageBrowserView. From what I see in the documentation I need to set up a dictionary with key-value pairs that describe the attributes of what I want to set it to. I have the snippet of code that I'm trying to use below: NSDictionary *titleTextInfo = [NSDictionary dictionaryWithObject: [CIColor colorWithRed:0.0 green:1.0 blue:0.0] forKey:@"titleColor"]; [myBrowserView setValue:titleTextInfo forKey:IKImageBrowserCellsTitleAttributesKey]; What I can't figure out is what is the magic key for setting the color of the title and subtitle. I've tried: foregroundColor, ForegroundColor, color, Color, titleColor, TitleColor and probably a few others. I've also tried using both CIColor (as shown above) and NSColor. As far as I can tell from a search of the documentation the actual keys are not documented. Any help would be greatly appreciated. Thanks very much. Thaddeus O.

IKImageBrowserView with NSArrayController bindings
Hi list,
i have an IKImageBrwoserView bound to an NSArrayController of objects.
The objects all conform to the IKImagebrowserItem protocol.
When running my application, all the images display correctly in the
browser view, this al works fine, BUT:
In the IKImageBrowserDelegate, i implemented
imageBrowserSelectionDidChange like this for testing purposes:
(I also have an IBOutlet to my NSArrayController)
- (void) imageBrowserSelectionDidChange:(IKImageBrowserView *) aBrowser
{
NSLog([[arrayController selectedIndex] description]);
}
The problem is that the NSArrayController always logs the same index,
no mather what item i select in de BrowserView.
I assumed that it would always reflect the currently selected index.
I can fix it by doing this but i am not sure if this is the right way
to go, or is it just a bug in IKImageBrowserView?
- (void) imageBrowserSelectionDidChange:(IKImageBrowserView *) aBrowser
{
[arrayController setSelectionIndexes:[aBrower selectionIndexes]];
NSLog([[arrayController selectedIndex] description]);
}
Help would be much appreciated.
Thanks,
Florian.

Re: IKImageBrowserView Dragging outside
Thanks for that, Thomas. The Problem I'm having is that the IKImageBrowserView is just representing previews. So it's a file preview and there's a path behind the preview to be copied when dragging out. With the standard settings of the view, I'll get the preview image copied to the location instead of the file behind the image.

This is not something specific to the IKImageBrowserView here so the pasteboard
programming guide should help:
http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/PasteboardGuide106/Introduction/Introduction.html
Typically you will have to do something like this:
- (NSUInteger) imageBrowser:(IKImageBrowserView *) aBrowser
writeItemsAtIndexes:(NSIndexSet *) itemIndexes toPasteboard:(NSPasteboard
*)pasteboard
{
NSUinteger index;
//instantiate an array to store paths
filesArray = [NSMutableArray array];
//for each index...
for(index = [itemIndexes firstIndex]; index != NSNotFound; index =
[itemIndexes indexGreaterThanIndex:index]){
//...get the path you want to add to the pasteboard
id myDatasourceItem = [_myDatasourceArray objectAtIndex:index];
NSString *path = [myDatasourceItem myLargeImageFilePath];
//add it to your array
[filesArray addObject:path];
}
//declare the pasteboard will contain paths
[pasteboard declareTypes:[NSArray
arrayWithObjects:NSFilenamesPboardType,nil] owner:self];
//set the paths
[pasteboard setPropertyList:filesArray forType:NSFilenamesPboardType];
//return the number of items added to the pasteboard
return [filesArray count];
}

Re: IKImageBrowserView Dragging outside
Thanks again Thomas and Jonathan. What you've written, Thomas, is
indeed working as it should however I can't use it for my project
since I am creating special folder structures when copying the files,
e.g. Adobe Photoshop Files -> 2008-10-20 -> MyPSFile.psd.
Isn't there a way to get the folder dropped to and then do the copy
operation myself? I am having an NSTableView that does pretty much the
same thing, look:
- (BOOL)tableView:(NSTableView *)tv writeRowsWithIndexes:(NSIndexSet
*)rowIndexes toPasteboard:(NSPasteboard *)pboard
{
if (NSNotFound != [rowIndexes firstIndex])
{
[array setSelectionIndexes:rowIndexes];
[pboard declareTypes:[self types] owner:self];
[pboard setPropertyList:[NSArray
arrayWithObject:@"ESPFilePromiseType"]
forType:NSFilesPromisePboardType];
}
return YES;
}
- (NSArray *)tableView:(NSTableView *)tv
namesOfPromisedFilesDroppedAtDestination:(NSURL *)dropDestination
forDraggedRowsWithIndexes:(NSIndexSet *)rowIndexes
{
[self restoreManagedObjects:[array selectedObjects]
withDestinationFolder:[dropDestination path]];
return nil;
}
Since the method 'tableView:namesOfPromisedFilesDroppedAtDestination:
…' doesn't exist I am currently out of luck.

An approach might be to use an NSTableView instance as a drag source
proxy.
When your IKImageBrowserView instance gets a drag request pass it on
to the tableview which can deliver on the promise.
You would have to keep the datasources synchronised of course.
Either that or populate the tableview with just the items to be
dragged when the IKImageBrowserView
drag begins.
Just an idea. Might be tricky to pull off in practice.

Re: IKImageBrowserView Dragging outside
Hey Jonathan & Thomas,
it's finally working and even more easier than I've thought: So I made
a subclass of my IKImageBrowserView and added a new delegate method,
the one's missing:
//
---
// -browserView:droppedIndexes:atDestination:
//
---
- (void)browserView:(ESPImageBrowserView *)bv droppedIndexes:
(NSIndexSet *)indexSet atDestination:(NSURL *)dropDestination
{
if (self.delegate)
{
if ([self.delegate
respondsToSelector
:@selector(browserView:droppedIndexes:atDestination:)])
{
[self.delegate browserView:bv droppedIndexes:indexSet
atDestination:dropDestination];
}
}
}
it's called from:
//
---
// -namesOfPromisedFilesDroppedAtDestination:
//
---
- (NSArray *)namesOfPromisedFilesDroppedAtDestination:(NSURL
*)dropDestination
{
[self browserView:self droppedIndexes:[self selectionIndexes]
atDestination:dropDestination];
return nil;
}
No need to implement :mouseDown- or -mouseDragged: :-)
Thank you for your help!
Best regards,

Ok, I didn't catch you need to create special folder structures.
So you can only do that with promised files and since there is no
equivalent to "tableView:namesOfPromisedFilesDroppedAtDestination"
in the IKImageBrowseView, you will have to do everything at the
NSView level using
"dragPromisedFilesOfTypes:fromRect:source:slideBack:event:" and
"namesOfPromisedFilesDroppedAtDestination:".
But that means you will have to detect when the drag should start
(with mouseDown/mouseDragged + IK's indexOfItemAtPoint) and setup
your drag image yourself.

IKImageBrowserView setSelectionIndex not selecting
I have been researching extensively on how to set an IKImageBrowserView's
initial selection upon load to 0 index. Here is the call I am making:
[imageBrowser setSelectionIndexes:[NSIndexSet indexSetWithIndex:0]
byExtendingSelection:NO];
Seems like the IKImageBrowserView is not fully loaded when the call is made,
however, I do have an IKImageView which is selecting and loading the first
object in the ImageBrowserView's object list correctly mat the same time I am
calling the same time. Here is the entire call:
- (void)updateDatasource {
[images addObjectsFromArray:importedImages];
[importedImages removeAllObjects];
[imageBrowser reloadData];
NSString *firstImagePath = [[images objectAtIndex:0] imageUID];
NSURL *firstImageURL = [NSURL fileURLWithPath:firstImagePath];
[previewImageStatic setImageWithURL:firstImageURL];
[pathTextField setStringValue:firstImagePath];
[imageBrowser setSelectionIndexes:[NSIndexSet indexSetWithIndex:0]
byExtendingSelection:NO];
}
I am not sure how I can get this call to select the object at index 0. I even
created an IBAction connected to a test button using the following code:
- (IBAction)selectImageBrowserFirstObject:(id)sender {
[imageBrowser setSelectionIndexes:[NSIndexSet indexSetWithIndex:0]
byExtendingSelection:NO];
}
And that works perfectly (since the IKImageBrowserView is already completely
loaded. Any ideas on how to work this out? Thank you in advance.

IKImageBrowserView reload data broken
Hello... I have an IKImageBrowserView that is not refreshing it's data
correctly. I have an NSPopUpButton which has a list of directories in its
array, when a directory is selected, it changes the contents of my
IKImageBrowserView to display all image files contained in the said directory.
Unfortunately, I have encountered an issue with the IKImageBrowserView's
"reloadData" call. When I have no objects selected in the IKImageBrowserView,
the reloadData call works as expected. The problem is, I have set
IKImageBrowserView's "setAllowsEmptySelection" to "NO" and (thanks to you all's
help) set the IKImageBrowserView to "setSelectionIndexes:[NSIndexSet
indexSetWithIndex:0] byExtendingSelection:NO];", so there is always a selection.
When my IKImageBrowserView has an object selected, the "reloadData" call gives
me the following error: "2009-07-01 14:28:43.453 ImageBrowser[17020:813] ***
-[NSCFArray objectAtIndex:]: index (2147483647( or possibly larger)) beyond
bounds (0)" and I have been unable to resolve this issue. Here is my call when
the NSPopUpButton's selection is changed which causes the problem at
"[imageBrowser reloadData]" on both the "if" and "else" statements:
- (IBAction) pubSelectionChanged:(id)sender {
NSString *selectedPUBItem = [[selectCategoryPUB selectedItem]title];
NSString *selectedCategoryPath = [NSString
stringWithFormat:@"/Users/richardg/Desktop/Demetras_Images/Thank You_Referral
Cards/%@", selectedPUBItem];
NSArray *categoryPath = [NSArray arrayWithObject:selectedCategoryPath];
if ([selectedPUBItem isEqualToString:@"All Images"]) {
NSString *allImagesPUBSelection =
@"/Users/richardg/Desktop/Demetras_Images/Thank You_Referral Cards/";
NSArray *allImagesPath = [NSArray
arrayWithObject:allImagesPUBSelection];
[images removeAllObjects];
[importedImages removeAllObjects];
[imageBrowser reloadData];
[NSThread detachNewThreadSelector:@selector(addImagesWithPaths:)
toTarget:self withObject:allImagesPath];
}
else {
[images removeAllObjects];
[importedImages removeAllObjects];
[imageBrowser reloadData];
[NSThread detachNewThreadSelector:@selector(addImagesWithPaths:)
toTarget:self withObject:categoryPath];
}
}
Any help here would be greatly appreciated. I looked extensively online and
came up with many dead ends. Thank you AGAIN in advance! You guys are always a
HUGE help!

2 IKImageBrowserView behaving differently
Hi all,
I have 2 tabs, with an IKImageBrowserView in each tab.
I have implemented imageBrowser:writeItemsAtIndexes:toPasteboard: so I
can drag images from one IKImageBrowserView to another, and have also
implemented imageBrowser:removeItemsAtIndexes: so images can be
removed.
However, reordering doesn't work:
- (BOOL) imageBrowser:(IKImageBrowserView *) view moveItemsAtIndexes:
(NSIndexSet *)indexes toIndex:(NSUInteger)destinationIndex
{
NSLog(@"we are moving items");
return YES;
}
This method isn't even called when I drag to reorder. There's also no
cursor that shows up when I move the images to a position.
Any idea what I can be doing wrong?

Updating IKImageBrowserView with Edited Image
Hi, all. Does anyone know how I could go about updating the content of my IKImageBrowserView after editing an image in an IKImageView? So... 1) User has some images in an IKImageBrowserView. 2) User selects an image. 3) The selected image shows in an IKImageView 4) User edits the image (Adjust color, resize, crop, rotate, etc.) 5) User selects another image. 6) Edited image replaces old version in IKImageBrowserView 7) New image shows in IKImageView 8) Repeat 4-7 The idea is that the user would edit several images and then save them all when they've made all the edits. Currently, I have steps 1-5 working, but when the selection changes, the edits are lost. So far I don't see a delegate for the IKImageEditPanel to call when it is dismissed or any way to bind the image of the IKImageView to the selected item in the IKImageBrowserView. Does anyone have an idea how I could accomplish what I want to do? Am I missing something obvious or should I file this as an enhancement request?

Troubles with CollectionView and IKImageBrowserView
Hello Macprogrammers
I've a problem with my IKImageBrowser in combination with a
CollectionViewItem.
I have a NSWindow with a NSCollectionView and a NSArrayController. I
extended the NSCollectionViewItem to reference the IKImageBrowserView
in an outlet and use the NSCollectionViewItem as a Datasource for the
IKImageBrowser (Connected together in Interface Builder):
NSWindows -> NSCollectionView (With NSArrayController) ->
MYNSCollectionViewItem (as ControllerItem) -> NSViewItem ->
IKImageBrowserView
In MyNSCollectionViewItem I've implemented following 2 Datasource
Methods:
- (int)numberOfItemsInImageBrowser:(IKImageBrowserView*)view
- (id)imageBrowser:(IKImageBrowserView *) view itemAtIndex:(int) index
But the IKImageBrowserView doesn't call these methods. I setup a
testmethod in the MYNSCollectionViewItem like the following code, to
verify that the imagebrowser outlet is set and to set again the
datasource:
- (IBAction)refreshView:(id)sender {
Album *representedObject = [self representedObject];
NSLog(@"UniqueData per row: %@", [representedObject uniqueData]);
[imageBrowser setDataSource:self];
[imageBrowser reloadData];
}
But even if i explicit set the IKImageBrowser DataSource to the
MYNSCollectionViewItem the DataSource methods wouldn't be called by
the IKImageViewBrowser. Do you know this problem? Outside the new
CollectionView with a simple implementation, this code works very well.
Kind regards from Lucerne (Switzerland)

IKImageBrowserView scrolling with core animation
I'm having some trouble with an IKImageBrowserView in a layer-backed NSScrollView. Everything works fine when the scrollers are hidden, but as soon as I have too many images to fit in the view, it gets confused. Specifically, when I scroll all the way to the bottom, I see my last row of images just fine. But as I scroll upwards, more and more of the view gets clipped, when I get to the top, the view is empty. I've tried turning off layer-backing, and it works perfectly - I only have the problem when layer-backing is on (I'm calling [view setWantsLayer:YES] on an ancestor of the scroll view). Is there anything I can do to fix this? thanks, -Dan Treiman ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: IKImageBrowserView with NSArrayController bindings
One more thing on this, if i bind an nstableview to my
NSArrayController (to just display the path to the image object) the
arrayController does reflect the changes, like so:
- (void)tableViewSelectionDidChange:(NSNotification *)aNotification
{
NSLog([[arrayController selectionIndexes] description]);
}
The log displays different indexes like it should, so i assume that
IKImageBrowserView could have a bug in it's bindings.
PS: is it enough to just bind the IKImageBrowserView to Controller Key
@"arrangedObject" without a Model Key Path?

I can fix it by doing this but i am not sure if this is the right

The problem is that the NSArrayController always logs the same

I assumed that it would always reflect the currently selected index.
NSArrayController doesn't respond to 'selectedIndex' -- I think you
mean 'selectionIndex'.
You should have got a compilation error for this. IAC, the index is an
integer, not an object, so you couldn't have usefully sent a
'description' message to it either.

Re: IKImageBrowserView and mouseDragged event
Sandeep, If your datasource returns paths, your view should be automatically a drag source. If your datasource returns images, I think the only thing you have to do is to implement - (NSUInteger) imageBrowser:(IKImageBrowserView *) aBrowser writeItemsAtIndexes:(NSIndexSet *) itemIndexes toPasteboard: (NSPasteboard *)pasteboard; in your datasource and fill the pasteboard with the info you want for the specified indexes. more info here: http://developer.apple.com/documentation/GraphicsImaging/Reference/IKImageBrowserDataSource_Protocol/IKImageBrowserDataSource_Reference.html#//apple_ref/occ/instm/NSObject/imageBrowser:writeItemsAtIndexes:toPasteboard: http://developer.apple.com/documentation/GraphicsImaging/Conceptual/ImageKitProgrammingGuide/ImageBrowser/chapter_4_section_6.html -- Thomas.

Re: IKImageBrowserView and mouseDragged event
Sandeep, Sorry, I misread your question. I have an application that implements dragging from an IKImageBrowserView and when I was testing it initially, I experienced a similar issue (no dragging being initiated on mouse down) when I forgot to connect the datasource outlet on my IKImageBrowserView. regards, douglas On Nov 28, 2008, at 11:57 AM, Sandeep Chayapathi wrote: I did try the -setDraggingDestinationDelegate: , but it is meant for a drag destination and not drag source.

IKImageBrowserView and the View Hierarchy
I have had a number of troubles with IKImageBrowserView not respecting other views trying to draw over the top of it. I have worked around some of the issues, but this latest I can't seem to resolve. I am trying to "dim" several of the views in my window by simply placing a translucent view over the top of them. This works as expected, *except* for the IKImageBrowserView... it always "shines through" and appears to be the top-most view. I did find that if I force the translucent view to be layer backed by - setWantLayer:YES, then the *background* of the IKImageBrowserView becomes appropriately dimmed, but the loaded images just disappear! This is *almost* repeatable with zero lines of code just using Interface Builder. You can drag an instance of IKImageBrowserView on a new window, then try to overlay another view, like an ImageWell or something. You'll see that the ImageWell is always below the IKImageBrowserView unless you tell it to be layer backed (although the layer-backing trick doesn't work in the simulator). What's going on here? IKImageBrowserView is clearly doing something fancy -- any ideas what that is and how I can get it to behave like a normal NSView?

Custom drawing in IKImageBrowserView fails
Hi list,
i'm trying to override an IKImageBrowserView to do some custom drawing but i'm
stuck.
What i try to accomplish is that when the view contains zero items, some custom
drawing happens like drawing an NSAttributedString that says "Drop items
here..."
Problem is that my drawing code gets never called.
Here's the drawRect method of my IKImageBrowserView:
- (void)drawRect:(NSRect)rect
{
[super drawRect:rect];
NSUInteger numItems = [[self dataSource]
numberOfItemsInImageBrowser:self];
if(numItems <= 0)
{
NSLog(@"No items in me"); // This gets called, so i'm sure the
above code works
NSRect bounds = [self bounds];
bounds.size.width = 200;
bounds.size.height = 200;
bounds.origin.x += 200;
bounds.origin.y += 200;
//[NSGraphicsContext saveGraphicsState];
[[NSColor yellowColor] set]; // Just for testing purposes
NSRectFill(bounds);
//[NSGraphicsContext restoreGraphicsState];
}
}
Uncommenting the NSGrahicsContext doesn't help either.
Anyone has any ideas or workarounds for this?
Thanks in advance,
Florian

Animation layer conflict w/ IKImageBrowserView
Does anyone know why an IKImageBrowserView won't draw if its SUPERVIEW has a Core Animation layer? NOTHING appears in the image browser view -- not even a white background. I'm enabling the CA layer on the superview using "setWantsLayer:YES". As soon as I remove that line, the image browser starts working correctly. I'm guessing that the IKImageBrowserView has its own animation layer that's conflicting with the super's animation layer(?)

reloading IKImageBrowserView in an IBAction
Hi.
I followed the excellent article 'Image Kit Programming Guide' at
http://developer.apple.com/documentation/graphicsimaging/Conceptual/ImageKitProgrammingGuide/Introduction/chapter_1_section_1.html#//apple_ref/doc/uid/TP40004907-CH1-SW1
and have my ImageBrowser working. I want to use it as the basis of an
image-uploader and would like to visualize the upload-progress by
removing the first image. I have connected a button to an IBAction and
can remove the images one by one.
- (IBAction)listImagesButtonClicked:(id)sender {
NSUInteger n;
NSArray *myArray;
if ( [mImages count] > 0 ) {
myArray = [mImages objectAtIndex:0];
NSLog(@"%@", [myArray description]);
[mImages removeObjectAtIndex:0];
[mImageBrowser reloadData];
n = [mImages count];
[numberOfImagesOutputField setIntValue:n];
// sleep(1);
}
}
[mImages removeObjectAtIndex:0] removes the first image and
[mImageBrowser reloadData] animates it.
I changed the 'if' to a 'while' but it doesn't animate removals one by
one but is waiting with [mImageBrowser reloadData] until all images
are removed (perhaps IBAction blocks it?) and remove all images at
once.
How can I make the [mImageBrowser reloadData] refresh within the while-loop?

IKImageBrowserView is not reloading data.
Hi, Given an IKImageBrowserView that is populated with valid IKImageBrowserItem, calling 'reloadData' on the image browser view does not actually reload the data for me. The documentation says that it "Marks the receiver as needing its data reloaded" but how and when does the reload actually take place? My application is a Core Data application and I initially thought the problem was related to bindings and updating of the managed object behind the image views back, but then I came across the sample code at apple.dev and realized that the problem still existed: http://developer.apple.com/samplecode/IKImageBrowserViewWithCoreData So then I boiled it down to the most basic scenario I could think of and the problem still exists. I can trigger this "bug" with something as simple as an image view backed by data source that just returns IKImageBrowserItem, who's imageRepresentationType is IKImageBrowserPathRepresentationType and who's imageRepresentation is just a path on the local file system. The following is reproducible for me. Hopefully I'm just missing something obvious. Comments are welcome. 1. Launch application 2. Populate image browser view with two items who return 'nil' when asked for their imageRepresentation. (ImageBrowser will correctly show the empty box for each.) 3. Click on a button that simply calls a method that assigns a valid path to each item. (The path represents an image on the disk.) 4. Call reloadData on the image browser and the empty boxes will correctly be replaced with the appropriate images. 5. Now, replace each items path with another valid path on the filesystem that points to a different photo. 6. Call reloadData. 7. This time, the images are not updated. In fact, no matter what I seem to do, the only time I can actually get the image browser to reload the data is when the items don't return a valid imageRepresentation. All other times, the image browser view seems to ignore my requests for a reload, and doesn't even call any of the IKImageBrowserItem methods at all. (Though it does if the items are initially nill). So, if the image browser view is already populated with valid items, the reload appears to fail for me. If the image browser view is populated with items that have an invalid imageRepresentation, the reload appears to work. Thoughts?

Any ideas??

Where do you call this from?
You'll need to call it from -awakeFromNib to ensure the view is loaded.

Re: IKImageBrowserView setSelectionIndex not selecting
You need to call [imageBrowser reloadData]. When you call
setSelectionIndexes there need to be items in the list calling
reloadData will ensure that there are items.

Re: IKImageBrowserView setSelectionIndex not selecting

My guess is that there's nothing to select, because you are loading
images in a second thread, and at the time setSelectionIndexes is
called, the thread hasn't managed to load even the first image yet.
You'll need to arrange for the thread to tell the main thread when it
has done some work so that the first thread can perform the selection.

Re: IKImageBrowserView only horizontal scrolling

Weird issues with IKImageBrowserView reloaddata
Hi,
I'm seeing some weird things reloading the data in my
IKImageBrowserView in my GC collected, Leopard app. Basically
depending on how I change the contents of my "filteredItems"
NSMutableArray I get a different loading behaviour.
If I refresh the contents like this the IKImageBrowserView seems to
ignore the imageUID and reload everything again:
[self.filteredItems setArray: self.prefilteredItems];
[imageBrowserView reloadData];
while if I do the much more elaborat following it seems to reuse
everything properly and doesn't do the weird reloading of everything:
NSMutableArray *array = [NSMutableArray arrayWithCapacity:
[self.filteredItems count]];
for(id obj in self.filteredItems){
if(![self.prefilteredItems containsObject: obj])[array
addObject: obj];
}
[self.filteredItems removeObjectsInArray: array];
for(id obj in self.prefilteredItems){
if(![self.filteredItems containsObject: obj])[self.filteredItems
addObject: obj];
}
Any idea why this is? How come the imagebrowserview seems to monitor
my mutablearray?
Also, any tips on how to solve the issue, or a workaround? The above
one is (too) slow.
I have done everything accoding to the ImageKit demo, including
implementing imageUID in my model object, and implementing the
delegates as follows:
- (NSInteger)numberOfItemsInImageFlow:(IKImageFlowView*)view{
return [filteredItems count];
}
- (id)imageFlow:(IKImageFlowView *) view itemAtIndex:(NSInteger) index{
return [filteredItems objectAtIndex:index];
}
Thanks,
Alex

Odd issue causing IKImageBrowserView to crash?
Greetings everyone. I am writing an application using IKImageBrowserView. I wrote a NSMutableArray object to hold the source images which reaches about 500-700 regularly in number. First, I used some code to generate the images. Then I told the IKImagebrowserView to reload the datasource, my application crashed. And the console ouputed: *** -[IKImageCellDatasourceProxy copyWithZone:]: unrecognized selector sent to instance 0x11558400 *** -[IKImageCellDatasourceProxy copyWithZone:]: unrecognized selector sent to instance 0x11558400 I tried to reduce the number of images to 30-50, the application run perfectly. After restored to 500-700, it crashed again. Can anyone tell me what is the source of this issue, and how to solve it? Thank you very much for any guidance.

How to use bindings with IKImageBrowserView?
I am attempting to use bindings to supply an IKImageBrowserView with data. I have successfully used IKImageBrowserView with a data source, but cannot get bindings to work. Should it work with bindings? The array controller's contentArray is hooked up to an NSMutableArray called storedImages. That contains instances of storedImage. And those have a method browserObject that returns instances of an object that implements the IKBrowerItem protocol to fetch and display an image (uid, path, etc). The Image Kit browser is bound to the array controller's arranged objects with the model key path browserObject. It is set to automatically prepare content. I get no images displayed even though there are plenty in the storedImages array. I am telling the browser view to reload its data. If I set a breakpoint at browserObject, it is never hit. So it looks like the array controller is never attempting to read my model. I get no errors when loading my nib. -- Blog: http://www.bagelturf.com/ Photos: http://bagelturf.smugmug.com/ ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: IKImageBrowserView spacing and contextual menus
Hi Yann,
On Apr 19, 2008, at 10:51 AM, Yann Disser wrote:
Is there a way to change the spacing of the images in an
IKImageBrowserView? In InterfaceBuilder?
No, the only thing you can do to impact the cell-spacing is to use
setCellSize and give a non square size (a size taller than larger=>
more vertical spacing, a size larger than taller => more horizontal
spacing).
How can I assign a right-click menu/contextual menu to an image
browser view? Connection a NSMenu with the menu-outlet in
InterfaceBuilder works for all of my views except the
IKImageBrowserView.
I don't know using InterfaceBuilder but programmatically I'm using the
optional delegate methods :
- (void) imageBrowser:(IKImageBrowserView *) aBrowser
cellWasRightClickedAtIndex:(NSUInteger) index withEvent:(NSEvent *)
event
and
- (void) imageBrowser:(IKImageBrowserView *) aBrowser
backgroundWasRightClickedWithEvent:(NSEvent *) event
to manage contextual menus.
For instance to add a contextual menu on a given item:
- (void) imageBrowser:(IKImageBrowserView *) aBrowser
cellWasRightClickedAtIndex:(NSUInteger) index withEvent:(NSEvent *)
event
{
//contextual menu for item index
NSMenu* menu;
menu = [[NSMenu alloc] initWithTitle:@"menu"];
[menu setAutoenablesItems:NO];
[menu addItemWithTitle:[NSString stringWithFormat:@"Open"] action:
[...] keyEquivalent:@""];
[menu addItemWithTitle:[NSString stringWithFormat:@"Get Info"] action:
[...] keyEquivalent:@""];
[NSMenu popUpContextMenu:menu withEvent:event forView:aBrowser];
[menu release];
}

Jens is right in that copying the collection view is often a problem,
as NSView does not support the NSCopying protocol. There's some more
information on the way that NSCollectionView copies the view here:http://www.cocoadev.com/index.pl?NSCollectionView
(near the bottom).
I got it working like this:
- put your custom view initialisation in initWithCoder: (as that is
the one used to copy the original instance / unarchive your nib)
- in your view, have an IBOutlet that's connected to the
NSCollectionViewItem instance (called cvItem in my case)
- in awakeFromNib bind the properties you're interested in (as these
get restored / set correctly in the cloning process), e.g.
- (void)awakeFromNib
{
[self bind:@"plotRoot" toObject:cvItem
withKeyPath:@"representedObject" options:nil];
[self bind:@"isSelected" toObject:cvItem withKeyPath:@"selected"
options:nil];
}
This setup works fine for me (ignoring the other known bugs and
documentation deficiencies of NSCollectionView — it's slightly
disheartening when you file a bug on it, get a dup back and realise
it's been known long enough for 1094954 other bugs to be filled..).

If I initialize the imageBrowser in my MYNSCollectionViewItem and set
the datasource, the datasource methods will now be called correctly.
Thank you. But it seems that the IKImageBrowserView which is displayed
will not display anything, even if I reload the imageBrowser data
manually:
- (id)initWithCoder:(NSCoder *)decoder {
imageBrowser = [[IKImageBrowserView alloc] init];
[imageBrowser setDataSource:self];
return self;
}
//
-
// numberOfItemsInImageBrowser:view
//
-
- (int)numberOfItemsInImageBrowser:(IKImageBrowserView*)view
{
MyObject *representedObject = [self representedObject];
return [representedObject.myImages count];
}
//
-
// imageBrowser:view:index:
//
-
- (id)imageBrowser:(IKImageBrowserView *) view itemAtIndex:(int) index
{
MyObject *representedObject = [self representedObject];
return [representedObject.myImages objectAtIndex:index];
}
- (IBAction)refreshView:(id)sender {
[imageBrowser reloadData];
}

Re: IKImageBrowserView and the View Hierarchy
I finally came up with a simple work around to this problem, one which actually works better for my purposes: instead of adding a view to the window's view hierarchy, add a new child window to the window. The view ordering then works as expected and doesn't break (or get broken by) IKImageBrowserView. Hope that helps someone else, Jeffrey On Dec 28, 2008, at 11:02 PM, Jeffrey J. Early wrote: I have had a number of troubles with IKImageBrowserView not respecting other views trying to draw over the top of it. I have worked around some of the issues, but this latest I can't seem to resolve. I am trying to "dim" several of the views in my window by simply placing a translucent view over the top of them. This works as expected, *except* for the IKImageBrowserView... it always "shines through" and appears to be the top-most view. I did find that if I force the translucent view to be layer backed by -setWantLayer:YES, then the *background* of the IKImageBrowserView becomes appropriately dimmed, but the loaded images just disappear! This is *almost* repeatable with zero lines of code just using Interface Builder. You can drag an instance of IKImageBrowserView on a new window, then try to overlay another view, like an ImageWell or something. You'll see that the ImageWell is always below the IKImageBrowserView unless you tell it to be layer backed (although the layer-backing trick doesn't work in the simulator). What's going on here?

How to make single-row IKImageBrowserView?
Hello Nice Cocoa People: I'd like to be able to create an IKImageBrowserView that only displays a single row of items that scrolls horizontally as needed. I didn't find any public API for doing this, even though (from what I understand at least) IKImageBrowserView uses NSCollectionView which has the setMaxiumumNumberOfRows: method. Is there some public way of accessing an IKImageBrowserViews's underlying NSCollectionView instance? Otherwise, is there some trick I'm missing? Someone suggested that I could programmatically set the size of by image browser view based on the cell size and the number of items, which I imagine would work, but I'm wondering if there's an easier way. Any help greatly appreciated. Best regards, John ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Custom drawing in IKImageBrowserView fails
Hi Florian,
You can't do custom drawing this way (because the IKImageBrowserView renders
into an openGL surface, so AppKit or CoreGraphics calls won't do anything).
So to do what you want you can either:
- make the view layer backed and add a sub-layer
- add an overlay transparent window on top of the image browser view
- add an overlay layer with setForegroundLayer: (that's the easiest solution
but it is SnowLeopard only).

Re: Custom drawing in IKImageBrowserView fails
Also, you could try swapping out the image browser (or making it hidden) when
it is empty, and display an alternative placeholder view in its place.
Also, file a bug report requesting the ability to do this built-in.

Re: Custom drawing in IKImageBrowserView fails
Hi Thomas,
thanks for the reply, i did try the first method you suggest with
adding a layer but it didn't work either.
I also tought of the second method but how would i make sure that my
IKImageBrowserView still receives drop event?
I ned to be compatible with 10.5 so method 3 is out of the question.
Thanks anyway!
Florian.

Problem is that my drawing code gets never called.
Here's the drawRect method of my IKImageBrowserView:

Uncommenting the NSGrahicsContext doesn't help either.
Anyone has any ideas or workarounds for this?

You should be able to set the overlay to be invisible to mouse events etc.

Re: Custom drawing in IKImageBrowserView fails
Thanks to all for the help.
i went with Mike's solution of swapping view.
I wrapped the IKImageBrowserView into a Tabless NSTabview with in the second
tab my "dropview".
I will also file the bug report as Mike suggested.
Thanks!

Answering my own question! :-)
Another thread (regarding nstimer) put me on the right track. Reading
about nstimer suggested the use of nsthread, so wrapping the removal
of images into a thread solved my issue:
-(void)removeImages:(id)sender {
while ( more images to remove ) {
[mImages removeObjectAtIndex:0];
[mImageBrowser reloadData];
etc.
}
}
- (IBAction)listImagesButtonClicked:(id)sender {
NSThread *myThread = [[NSThread alloc] initWithTarget:self
selector:@selector(removeImages:) object:nil];
[myThread start];
}

Re: IKImageBrowserView D&D with IKImageBrowserNSDataRepresentationType
Ha yes, I'm doing a from only. Now I've filled the pasteboard with my NSData objects for NSFilesPromisePboardType. Which methods should I implement if I don't want any drops enabled within the image browser but only to the finder? Any direction appreciated.

Re: IKImageBrowserView D&D with IKImageBrowserNSDataRepresentationType
Ok, thanks again, so far so good.
Now as I drag an image or multiple images it creates a thumb of the dragged
item(s), but as I drag to the desktop there's no plus sign badge on the dragged
items and as a drop on the desktop it doesn't accept. I guess what I need to
get is a
- (NSArray *)namesOfPromisedFilesDroppedAtDestination:(NSURL *)dropDestination{
And then perform the paste from my end. But I'm not receiving
namesOfPromisedFilesDroppedAtDestination. I've looked in the sample code and
the last example is from 2003.

IKImageBrowserView out drag & drop with NSData
Hi everyone, I'm using an IKImageBrowserView with data rep IKImageBrowserNSDataRepresentationType. I'm using - (NSUInteger) imageBrowser:(IKImageBrowserView *)aBrowser writeItemsAtIndexes:(NSIndexSet *) itemIndexes toPasteboard: (NSPasteboard *)pasteboard and filling the pasteboard with [pasteboard declareTypes:[NSArray arrayWithObject:(NSString *)kPasteboardTypeFileURLPromise] owner:self]; [pasteboard setPropertyList:imageData forType:(NSString *)kPasteboardTypeFileURLPromise]; imageData being an Array with NSData objects containing images. The drag works fine, A nice red badge appears if I select multiple items, then the plus sign appears as I hover above the finder, but as I drop - (NSArray *)namesOfPromisedFilesDroppedAtDestination:(NSURL *)dropDestination Doesn't get called. I'm stuck here, everything works fine, but I just need the drop location... I've tried subclassing IKImageBrowserView as shown on http://speirs.org/ But then the badge is gone, the thumbs of the first image is gone too, and I've got the feeling I will bump into problems with sublclassing all the mouse action later on in the project. Any help greatly appeciated. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

IKImageBrowserView image quality changing with redraw
I'm trying to move from a custom view to an IKImageBrowserView in a project, and running into a somewhat odd problem. Context: my IKImageBrowserItems are IKImageBrowserNSImageRepresentationType, backed by a relatively large (~600x800) NSImage. When first drawn, at any scale factor, this looks great. However, as soon as a redraw (not a reload!) occurs, the quality goes to hell. For example, clicking in the browserview will cause this problem instantly. It's as if it's deciding all of a sudden to fall back to a cached image of much lower quality. Scrolling seems not to trigger a redraw of this type; so if a large view containing as-first-drawn high quality images is clicked, only the currently visible thumbnails will get degraded, and scrolling can then present a mix of degraded and full-quality images. Needless to say, this huge a reduction in image quality is not acceptable. How can this be prevented? [Side note: I've seen reference to the prefetching behavior of IKImageBrowserView is particularly gnarly for NSImages as all the preload must be done on main thread since NSImage is not thread safe. With this in mind, what's the preferred type for IKImageBrowserItem backings?] Adam ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

IKImageBrowserView & IKImageView subclasses not getting called
I subclass IKImageBrowserView & IKImageView overriding initWithFrame: & drawRect: and sending the same messages to super in both cases. I've set them as the classes for the UI objects in my IB file, and as IBOutlets in my window's window controller subclass. But when I run the code, neither of my two subclasses ever get called. What gives? Is there anything else I need to do in my subclasses? If I set the IBOutlets in the contoller subclass and class types in IB back to IKImageBrowserView & IKImageView, the code seems to do the same thing as when I use my subclasses.

Re: How to use bindings with IKImageBrowserView?
It does work. I have defined a core data entity that conforms to
IKBrowerItem protocol and my IKImageBrowserView is working with
bindings. I think you still need to point the delegate and data source
outlets to an object that implements the datasource methods:
// -
// numberOfItemsInImageBrowser:view
// -
- (int)numberOfItemsInImageBrowser:(IKImageBrowserView*)view
{
// The item count to display is the datadsource item count.
return [[imageBrowserArrayController arrangedObjects] count];
}
// -
// imageBrowser:view:index:
// -
- (id)imageBrowser:(IKImageBrowserView *) view itemAtIndex:(int) index
{
return [[imageBrowserArrayController arrangedObjects] objectAtIndex:index];
}
// Implement some optional methods of the image browser datasource
protocol to allow for removing and reodering items.
// -
// removeItemsAtIndexes:
//
// The user wants to delete images, so remove these entries from the
data source.
// -
- (void)imageBrowser:(IKImageBrowserView*)view removeItemsAtIndexes:
(NSIndexSet*)indexes

[imageBrowserArrayController
removeObjectsAtArrangedObjectIndexes:indexes];

The array controller's contentArray is hooked up to an NSMutableArray

those have
a method browserObject that returns instances of an object that

The Image Kit browser is bound to the array controller's arranged

I get no images displayed even though there are plenty in the

If I set a breakpoint at browserObject, it is never hit. So it
looks like
the array controller is never attempting to read my model. I get no

Re: How to use bindings with IKImageBrowserView?
My IKImageBrowserView bound to an ArrayController is now spitting out
this error when the program launches
--ImageKit Error: reloadData called in non main thread
When I unbind it the error goes away along with the content no longer
being displayed. Any idea what could cause this?

Set the height of your browser view to whatever you'd like that will contain a single row of your image cells. Then in your controller's -awakeFromNib use [imageBrowser setContentResizingMask:NSViewWidthSizable] to tell it you only want it to expand horizontally. Apparently the default is NSViewHeightSizable and I see no way to override that via IB. The normal autosizing springs/struts in IB don't seem to affect the contentResizingMask at all for an IKImageBrowserView.

How to drag file promises from IKImageBrowserView?
Hi!
I'm using IKImageBrowserView to display a collection files that reside
on Bluetooth devices. From the documentation, it looks like the only
method you have to override to support dragging is:
- (NSUInteger)imageBrowser:(IKImageBrowserView *)aBrowser
writeItemsAtIndexes:(NSIndexSet *)itemIndexes toPasteboard:
(NSPasteboard *)pasteboard
I can't seem to be able to get the Finder to accept file promises
placed on the dragging pasteboard from IKImageBrowserView. Here is my
code:
- (NSUInteger)imageBrowser:(IKImageBrowserView *)aBrowser
writeItemsAtIndexes:(NSIndexSet *)itemIndexes toPasteboard:
(NSPasteboard *)pasteboard {
NSArray *fileExtensions ... ; // Get extensions of the dragged files
[pasteboard declareTypes:[NSArray
arrayWithObject:NSFilesPromisePboardType] owner:self];
[pasteboard setPropertyList:fileExtensions
forType:NSFilesPromisePboardType];
return [fileExtensions count];
}
Is there any way to support the dragging of file promises from
IKImageBrowserView so I could later save the actual data to disk
asynchronously?
Thanks,
Matt

Re: IKImageBrowserView image quality changing with redraw
Hi Adam, Is this on Leopard or Snowleopard ? I just tried to load images from /System/Library/Desktop Pictures in an IKImageBrowserView using the NSImage representation. They appears just fine for me (SnowLeopard). > [Side note: I've seen reference to the prefetching behavior > of IKImageBrowserView is particularly gnarly for NSImages as all the preload > must be done on main thread since NSImage is not thread safe. ?] This is true on Leopard, but not on SnowLeopard. > With this in > mind, what's the preferred type for IKImageBrowserItem backings If you images exists on the filesystem, it is preferable to use a path or url based representation. Otherwise, there is no preferred representation. -- Thomas On Dec 8, 2009, at 1:01 AM, Adam Berger wrote: > I'm trying to move from a custom view to an IKImageBrowserView in a project, > and running into a somewhat odd problem.

Re: IKImageBrowserView image quality changing with redraw
This has so far only been tested on SnowLeopard. I'm going to divide this into two issues, since I'm not 100% sure they're related. 1) On redraw, a filtering is applied that changes the image quality. Are you seeing this change on first redraw from a large NSImage (rather than from a url to an image)? 2) The filtering applied may actually be appropriate for photographs, but I'm dealing with line drawings, which become completely unusable when scaled in this way. Even zero antialiasing would be greatly preferred 3) (Not an issue, but a possible solution that didn't work.) If providing an NSImage with multiple NSImageReps that only vary in resolution, icon style, IKImageBrowserView seems to always work with the first/largest. If I could make this work, I'd just generate multiple thumbnails. (I suppose I could throw away all thumbnails on bump the version number on scale change... expensive, though.) I've put up three screenshots: • http://www.addaon.com/IKImageBrowserView_scaling_A.png is a manually-scaled high-quality image (about half the size of the original; just for comparison) • http://www.addaon.com/IKImageBrowserView_scaling_B.png is how it appears initially (before redraw); this is marginally acceptable • http://www.addaon.com/IKImageBrowserView_scaling_C.png is the over-filtered form Again, the transition between B and C happens whenever I cause a redraw, for example by clicking on the background. Hard to overstate this problem.
