CoreData -- addPersistentStoreWithType crashing
Hi all: I've been making some changes to one of my apps which include a change to the data model. Now whenever I start up the app it crashes (EXEC_BAD_ACCESS) in addPersistentStoreWithType:configuration:URL:options:error:. I've factored out all the passed arguments and it's still crashing. I figure it must have to do with the change in the model, but I can't see why that would make it crash and not report an error or trow an exception, particularly if the URL points to a nonexistent file )e.g. it will create a new store file). Any thoughts?

Re: how to manage two nib files

I have read these references, but I still have no idea about my issue, Maybe I did not understand them completely now, but I am worried that maybe I have not give a clear expression in my first email. Maybe I need give a more detailed description: this application is a utility for my printer, which be launched by the utility button on the Printer Setup Center. when user click the utility button, the Mac OS X will launch the linked application. and the application should first register an apple event, the Mac OS X then will send the apple event which used to tell my utility the printer model name and related information about the device. So, before the appliction be launched, it should get the apple event and check the printer name, then it will load the nib file dependently. If the printer is a USB printer, it will load a normal window to interact with user, if it is a Network, it will launch another application to do other things. So, I have no idea to design this application. I think this question maybe can not be implemented by cocoa application template, but I know that it seems no need to use NSDocument class. Thanks. You don't need to use the Document-based application template. An application typically has a main nib. This is configured using the Main Nib File field of the Properties tab of the info window for the target. The value of that field gets translated at build time into the NSMainNibFile key in the application's Info.plist file. The main nib is loaded by NSApplicationMain(). Often it contains the main window of your application, whatever that might be. However, the main nib can be reduced to contain only the main menu bar and nothing else. This allows you to defer the decision about what window to show until you receive the Apple Event you're expecting. When you do receive it, you can load whatever nib you like. Often, you use a custom subclass of NSWindowController. Have it both load the nib and act as the nib's owner. In your nib, you'd configure the class of File's Owner to be your custom class. You'd connect its window outlet to the main window in that nib. In your application controller, at the time when you realize which nib you want to load, you allocate and initialize an instance of your class, and ask it to show its window. That last step will cause it to load its nib, thereby instantiating the window and showing it. If for some reason you don't want to use NSWindowController to load the nib, you can use methods of NSBundle or NSNib to load the nib.

Re: Weird behavior of mouse location when performing a drag

Hello all.
Well Im performing a drag-ndrop between views of the same app, I

there was a gap of about 145ox in x coordinate and 45 px in the y
coord, those values are not even close to where the view resides in
the window. So what I did to fix the problem was the following.
- (NSDragOperation)draggingUpdated:(id NSDraggingInfo )sender
{
NSPoint converted = [NSEvent mouseLocation];
actualDragPoint = [self convertPoint:converted fromView:nil];
actualDragPoint.x = actualDragPoint.x - 144 ;
actualDragPoint.y = actualDragPoint.y -76;
return NSDragOperationMove;
}
it fixed the problem, but Im wondering why is this happening?
Any clues?

Re: Problems with multiple selection and NSArrayController
Hi, does the detail arraycontroller show all categories and selects the ones contained in the set of your selected master rows? Can't you just display only the detail categories that are within the set of the selected master? This would be easy to do even with multiple master objects selected via the Content Array For Multiple Selection binding of the categories controller. And it would reflect the expected Cocoa behaviour. Volker Am 10.12.2008 um 11:20 schrieb David Niemeijer: Hi, I have a master table that displays that gets it's contents NSArrayController with items.

Problem drawing outside of drawRect: in a custom table cell
I need to draw outside of the usual drawRect: method (no really, I do!)
The reason is that I have a custom cell that is used in a table/
outline view that draws a colour swatch. When clicked it pops up a
menu of colours so the user can choose another colour. While tracking
the menu, the cell shows the colour in the menu that the mouse is
over. When the mouse is released, the cell sends the chosen colour to
the table's datasource as usual.
The drawing of the colour while tracking the menu needs to take place
outside the drawRect: mechanism. Why? Because the host view is a
table, and I need to avoid it reloading the cell from the datasource
while I'm tracking the menu. If I invalidate the table view, it will
redraw the entire row. That would be OK if I could rely on it to draw
only my row, but in some circumstances I have found that it doesn't,
but redraws the whole table (for example after editing a text cell,
for some reason any setNeedsDisplayInRect: on a small part of the
table causes the whole table to reload). That stuffs up the cell
because its colour value can get switched out (to nil or another
colour) while it should really reflect what is being tracked in the
menu or was just chosen from the menu. (I have tried a whole lot of
tricks to try to make it work that way, believe me, but it's so
convoluted and I have so little control over what is happening in the
tableview that I have given up and am trying to work it by short-
circuiting the cell drawing, but only while tracking).
So anyway, things are almost working fine - in fact they do work fine
at all times except the very first use of the cell. If the table is
used in any way prior to clicking the cell (selecting any row, for
example), it works fine. But if the first ever click on the table is
on my cell, I get no drawing - it's as if the cell is clipped out
(though forcing the clip to my cell's rect doesn't fix this so it's
not actually that). For my cell to work, the table has to have done
something other than draw its rows.
I draw my cell like this:
- (void)drawImmediately
{
[mControlView lockFocus];
[self drawInteriorWithFrame:mFrame inView:mControlView];
[mControlView unlockFocus];
[[mControlView window] flushWindow];
}
where mControlView and mFrame are ivars that are set on entry to
the mousetracking method to be the hosting control view and the cell's
frame respectively. I have verified that mControlView is indeed always
valid and the correct object at this point. The cell rect is also good.
Maybe it s a graphics context problem? I have tried always setting the
current context to the view's window but that stops it from ever
working (which may be a clue). Anyone spot anything I'm doing or not
doing here?
Also, if you feel tempted to advise me not to do it this way, believe
me, I have exhaustively investigated that route, which has proven even
more problematic, because there's insufficient fine control over what
the tableview itself does in its own drawRect: method. So far this
approach is the cleanest by far.
tia,
Graham

Re: The thread that starts by NSTask didn't clear up
OK It seems that in leopard NSTask uses a thread to monitor the launched process, presumably to detect process termination. This thread should disappear shortly after the corresponding NSTask instance is released. Since the launched NSTask is auto-released you need to do one of the following: 1. Install a NSAutoreleasePool somewhere in your loop 2. Use [[NSTask alloc] init] and explicitly release your task when you're done.

Re: CoreData -- addPersistentStoreWithType crashing
Hi Ben- If you are using a custom class to represent an entity in your model, you must make sure that it is a subclass of NSManagedObject in your code (and not NSObject). This might not be your issue, but I have had this bite me before - it issues the same error with no exception thrown, and is quite a challenge to debug. I fall into this when moving fast in model creation, as the template for adding an Objective- C Class to a project makes it a subclass of NSObject. Hope this helps!

I have read up on the Carbon Alias Manager and the third party BSAlias/ NDAlias classes but none of these quite seem to fit the bill as it looks like I am working backwards from their designed use. ie, rather than finding the file from a database record, I want to lookup the database record from a known file. In this situation, would it be best to use -[NSFileManager attributesOfItemAtPath:error:] and store the NSFileSystemFileNumber? I'm not sure how resilient this approach is. Or is there something that I have missed completely? Regards, Ben ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Problems with multiple selection and NSArrayController
Volker, On Dec 10, 2008, at 11:42 AM, Volker in Lists wrote: does the detail arraycontroller show all categories and selects the ones contained in the set of your selected master rows? yes. Can't you just display only the detail categories that are within the set of the selected master? This would be easy to do even with multiple master objects selected via the Content Array For Multiple Selection binding of the categories controller. And it would reflect the expected Cocoa behaviour. The problem with doing that is that it would make it more complicated for the user to add new categories, as in that case the detail table would only show the already selected categories and thus offer no way to select additional categories. Currently adding more categories to an item is just a matter of selecting multiple ones. What you are suggesting implies adding a different user interface for adding categories to an item. Maybe that is the only solution or even best solution? david.

Each of those items has a categories key which contain an NSMutableIndexSet. When the user selects a row in the master table my app displays in a detailed view a detail table with categories. The contents of that detail table comes from a categories NSArrayController and the selection is determined by the index set of the categories key of the selected item of the master table. If the user changes the selection in that detail table the indexes nicely update for the selected item of the master table. Up to this point everything works fine so far. Now I add multiple selection to the master table. When two selected items in the master table have index sets that contain the same indexes everything is still ok, but when the each have different indexes a problem will occur. No categories will get selected in the detail table and when I click elsewhere in the master table the category indexes of the two originally selected items will become empty sets. So, what would I need to do to prevent problems with multiple selection in the master table?

Static and Dynamic libraries for iPhone apps ?
Hi All, 1) Can we build e.g. XCODE menu File = Project New = Static Library Cocoa And later use it for iPhone application to be linked with it? 2) the same question for DYLIB Cocoa, and then to be used with iPhone app e.g. If we put it inside of app bundle Just sometimes it is comfortable to put something into libs, and then only link to APP. Will this work? I believe answer is yes, because iPHone self contains tons of BSD dylibs and static libs. So we can also do this? If yes, so we can produce both? BSD and Cocoa libs? -- Best regards, Ruslan Zasukhin VP Engineering and New Technology Paradigma Software, Inc Valentina - Joining Worlds of Information http://www.paradigmasoft.com [I feel the need: the need for speed] ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Searchable persistent file reference
FSRef is the data type for referencing a particular file by record, however it's not the pleasant to work with. Have you considered using NDAlias etc. but setting them to resolve references by file ref, then path. (By default, the alias manager looks up aliases by path first, then file ref).

I am not sure that NSFileSystemFileNumber will be available or persistent for some volume formats. I think you should stick with the alias approach. If you need to match a moved file, then just resolve all the aliases in your database until you find the file you are looking for. You could maybe speed up 'normal' searching by keeping a hash of the relative path from the database to the file and searching for that first, and only fall back to the full scan if that fails. (If a relative path is not available (i.e crossing volumes/servers) then just hash the full path of the file.) ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Very odd issue when try to implement the drag and drop functions for NSOutlineview
Hi, everyone.
Currently I am working on a project which uses the NSOutlineview heavily. I
thought the drag and drop functions are very important, so I am trying to
implement that.
However, after refer to some tutorials, I still can't make it work... My
steps are :
1. create a controller to manage the outlineview, set the controller to the
datasouce and delegate for the outlineview.
2. register the outineview with the following code in the awakeFromNib
method:
[_outlineView registerForDraggedTypes:
[NSArray arrayWithObject:MyPrivateTableViewDataType]];
3. implement the following methods:
- (BOOL)outlineView:(NSOutlineView *)ov
writeItems:(NSArray *)items
toPasteboard:(NSPasteboard *)pboard
{
draggedNodes = items;
NSlog(@In the outlinew writeItems method!);
[pboard declareTypes:[NSArray
arrayWithObject:MyPrivateTableViewDataType] owner:self];
[pboard setData:[NSData data] forType:MyPrivateTableViewDataType];
return YES;
}
- (NSDragOperation)outlineView:(NSOutlineView*)ov
validateDrop:(id NSDraggingInfo)info
proposedItem:(id)item
proposedChildIndex:(NSInteger)childIndex{
NSLog(@Return the NSDragOperation);
draggedNodes = [[[info draggingSource] dataSource] draggedNodes];
return NSDragOperationGeneric;
}
- (BOOL)outlineView:(NSOutlineView *)ov
acceptDrop:(id NSDraggingInfo)info
item:(id)item
childIndex:(NSInteger)childIndex
{
NSLog(@should we return the accetpDrop?);
return YES;
}
After compiled the application and set it up, I had no chance to
successfully get anything from the console although there are so many output
statements when I drag and drop items repeatly.
Can anyone here give me some help or guidance about this issue?
Thank you very much for any help. Good luck.

Re: Very odd issue when try to implement the drag and drop functions for NSOutlineview
Hi,
This was a reply that i posted recently for a similar question, i
think you are missing step 2
To re-order the items in the tableView, you will have to implement a
custom drag type.
Say for example you name your custom drag type as @myDragType
then
1] Register your table view to accept this drag type using
registerForDraggedTypes: and passing an array containing
@myDragType along with super's drag types
2] In your tableView's data source, implement this method
tableView:namesOfPromisedFilesDroppedAtDestination:forDraggedRowsWithIndexes
: and return an array containing @myDragType.
3] Implement tableView:writeRowsWithIndexes:toPasteboard: in your
data source and write any dummy data in the given pasteboard for type
@myDragType, this can be the data representing the items/indexes
being dragged
4] Check for a valid drop with
tableView:validateDrop:proposedRow:proposedDropOperation:
5] Finally set the new indexes for the dragged items in
tableView:acceptDrop:row:dropOperation:

References are a language feature of C++. Neither C nor Objective-C
has such a notion. You would have to use Objective-C++, which is
usually accomplished by using a .mm extension for your source file.
Note that if you use C++ features in a header file, then all
translation units which include that header will have to be C++ or
Objective-C++, unless you conditionalize the code with #ifdef
__cplusplus.

Ken

Re: how to pass arguments by reference
Spoke too soon... whoops.
Put an asterisk before the type, indicating that the type is going to
come in as a pointer to the data and not the actual data. Then when
you call the method, you use the ampersand to pass a pointer to your
data, like so:
(in some class definition somewhere. A C function would have slightly
different syntax, shown below):
- (void) foo:(*int)bar {
(*bar)++;
}
Then elsewhere,
int baz = 42;
NSLog(@%d, baz);
[someReceiver foo:baz];
NSLog(@%d, baz);
You should see 42 printed, and then 43.
If you wanted to declare foo as a C function, you'd do it like so:
void foo (int *bar) {
//same stuff
}
Welcome to the wonderful world of pointers.

IB Scroll View position problem
I have two scroll views in my application, each with a table view, in addition to a bunch of other items. Everything is locked to the upper left corner of the window view. When the window is resized, I would like the scroll views to expand and shrink along with the window. The smaller scroll view is located on the left, near the middle of the window, is fixed width and and extends down to the bottom of the window. Everything is fine as long as the window expands and shrinks to a vertical size no smaller than the original size. However, if I make the window smaller, vertically, then the scroll view assumes a vertical position that is higher in the window than the original location. In IB in the scroll view size, autosizing box, I have the top, left, and bottom constraints and only the vertical resize constraint. I think this may be a bug. IB version is 3.0 (629).

Re: how to pass arguments by reference
What you're looking to do is a C++ism, it's not available in Objective-
C; there's no explicit support for pass by reference.
It's certainly possible to achieve the same ends though. For
primitive types, you'll have to pass a pointer. Declare the method as
taking, for example 'int *' if you want to pass a pointer-to-int, and
call it by taking the address of the thing you want to pass a pointer
to (e.g. use 'myInt' if 'myint' is the primitive you want to pass by
reference).
For Obj-C objects, 'pass by reference' effectively always happens,
because you have to pass a pointer to the object (like an
'NSMutableString *') anyway.

NSTextField setStringValue not updating properly
Namaste! I've written a simple interface for ICA as part of my application. In that interface I have an NSTextField which holds a default path filename. Next to that field I have an NSButton for changing that information. It opens an NSSavePanel. I also have a Preview button that grabs the image on the scanner bed. This process downloads the file to a temporary directory filename. I pass the resulting path and filename via an IBOutlet which is hooked to the text field. These values can originate from the scan preview operation, the user typing, or the change button operation. The text field is not bound to any datasource. It *appears* to work on the surface, athough sometimes not even then. This is confusing the heck out of me. Anytime the value for the text field needs to change, I call [NSTextField setStringValue:(NSString *)aString]. After searching through the message archives, I either find bound fields or something else. The messages that address stuff close this stipulate using the above call. I have also tried validateEditing and display, both to no avail. I can't seem to locate another viable method to get the data stored (like a refresh). What appears to happen (in terms as best I can describe it, not necessarily technically correct) is that the text is written to the control's view, but, isn't saved to the underlying data structure. Thus, when I actually need the value later, I don't get what I see currently, but what was stored before. Hopefully that will make sense. In other words, it is as if there are two values: one for display, and one for data. They don't appear to get synched when I use setStringValue. So, my question is, what do I need to do to get the value actually stored and not just displayed? Thanks in advance! Peace, Love, and Light, /s/ Jon C.

RE: how to pass arguments by reference
While I'm not sure if the GCC objective-C compiler accepts C++ references (I've

used as opposed to the C compiler.

Re: Problem drawing outside of drawRect: in a custom table cell
On Dec 10, 2008, at 2:44 AM, Graham Cox wrote: I need to draw outside of the usual drawRect: method (no really, I do!) The reason is that I have a custom cell that is used in a table/ outline view that draws a colour swatch. When clicked it pops up a menu of colours so the user can choose another colour. While tracking the menu, the cell shows the colour in the menu that the mouse is over. When the mouse is released, the cell sends the chosen colour to the table's datasource as usual. The drawing of the colour while tracking the menu needs to take place outside the drawRect: mechanism. Why? Because the host view is a table, and I need to avoid it reloading the cell from the datasource while I'm tracking the menu. If I invalidate the table view, it will redraw the entire row. That would be OK if I could rely on it to draw only my row, but in some circumstances I have found that it doesn't, but redraws the whole table (for example after editing a text cell, for some reason any setNeedsDisplayInRect: on a small part of the table causes the whole table to reload). There are various reasons why this happens; for one, the focus ring may bleed into the rect that was invalidated. But, as you have noticed, you should not rely on invalidating just a small portion and hoping only that portion should redraw. I think it is still correct to invalidate your cell's rect, and have the table redraw (potentially redrawing everything). ,,,.. Maybe it s a graphics context problem? I have tried always setting the current context to the view's window but that stops it from ever working (which may be a clue). Anyone spot anything I'm doing or not doing here? Also, if you feel tempted to advise me not to do it this way, believe me, I have exhaustively investigated that route, which has proven even more problematic, because there's insufficient fine control over what the tableview itself does in its own drawRect: method. So far this approach is the cleanest by far. I think you should try another approach. Go back to invalidating the rect of the cell that you want to redraw. Essentially, you want one cell to maintain specific state while you are doing something else. There is one easy approach to do this, which is to maintain a copy of the cell while you are showing your special menu, and use that cell to draw *just* that one particular row/column. General steps: 1. Save off the row/column 2. Copy the cell at that row/column when showing your menu 3. Always return that copied cell from the delegate method: - (NSCell *)tableView:(NSTableView *)tableView dataCellForTableColumn: (NSTableColumn *)tableColumn row:(NSInteger)row AVAILABLE_MAC_OS_X_VERSION_10_5_AND_LATER; else, return [tableColumn dataCell]. 4. Don't update the properties for that row/column in -willdisplaycell 5. Update the colors of that copied cell when your menu changes state 6. Drop the copied cell when your menu goes away. Another approach would be something similar to this great example: http://developer.apple.com/samplecode/PhotoSearch/ .corbin ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Date Formatter year input without year display
Hi- I ran into a problem with my production scheduling application as the new year approached. In IB I am using a 10.0 date formatter bound to NSDate properties of a model object. I used: %1m/%1d, %1I:%M%p which gave me something like: 12/23, 12:30PM This was used mostly for display, but the user is also able to type into the edit field in order to change the value. As the new year came into play, he might have changed 12/23 to 1/5. My thinking was that if he entered just 1/5 it would assume the current year, which seems to be correct. But I thought if he entered 1/5/2009, then Cocoa would help me out and do the right thing. In fact, even when entering the year explicitly, the formatter still made the data be 1/5/2008. I had to add the year to the formatter string to make it accept the year as input. Is this expected? Is there a good way to only display the month and day, and yet allow the year to be entered if desired?

NSView subviews mutability - follow up to NSDictionary mutability test thread
A follow up of sorts to Cocoabuilder - ([EMAIL PROTECTED]) NSDictionary mutability test from Cocoabuilder - (Bill Bumgarner) Re: NSDictionary mutability test Performance An NSMutableDictionary instance can be returned from a method declared as returning (NSDictionary*) without risk that the client is going to go and change the contents behind your back.

I just did a quick test using -[NSView subviews]. The return type is NSArray*, but if you send -addSubview: to the view, the size of the previously returned array grows by 1.

Re: How Can I Notify DrawRect Method?
You both have valid points. However, I think you are missing something. That something being the overall goal of the application as predicated by that never-ever-returns: Time. That goal can be multi-faceted. For example, one item in the overall list is target platform. By deciding on what platform(s) to target, you can decide where to spend your time during to development to achieve the results you want. Sometimes that decision can also lead to split forks in the development tree (e.g., platform-specific support). Since I have found it nearly impossible to develop the perfect app before writing any code or going into some sort of demo mode, I favor an iterative design loop: get program parameters, code, test, check against parameters, check with client, lather, rinse, repeat. During that design/construction cycle, one should be able to identify what needs optimization, etc. That will cut down on the debate of technical theory - the proof being mostly in the pudding. Of course, the theory can help identify potential hotspots (items to watch) which can then be checked during testing cycles. Neither development time nor optimization are distinctly separate in my view - they are interdependent given the goal of the application. One may get favored over the other, but, again, that depends upon the restrictions placed by the goal of the application. Quoting Michael Ash [EMAIL PROTECTED]: On Wed, Dec 10, 2008 at 7:05 AM, I.

is to do:
NSString *characters = [theEvent characters];

case NSNewlineCharacter:
case NSCarriageReturnCharacter:
}

Re: Detecting the Enter Key
I would go for the second one. I would guess that the second one would
pick up all the various Enter keys, whereas the first would only pick
up a single key. The second also looks much more elegant to me. I do
not have any experience with this; I am merely saying what looks best
from my point of view.

Re: Searchable persistent file reference
An alias stores quite a bit of information in it to allow you to find a file object (files, folder, disks) if it moves or is renamed or if any of the elements of its path is renamed, and can usually work with varied file systems.

Hi, when you build your app in Xcode with the Release target setting, you will get your app with the standard app icon in the build folder. This folder usually resides within your project directory. Via the targets Get Info panel you can set app icon - which you have to supply yourself, to get a custom icon. This app you can send to others.

Re: how to pass arguments by reference
C, and by extension Objective-C, do not have references in the C++
sense. You'll have to pass a pointer to the thing that you want your

But the error when compiling is parse error before token.
Is passing by reference not allowed or is there any other syntax

It really depends on whether you want to detect the physical key or
the logical key. Input methods may conceivably change the mapping from
one to the other and how you want to check will depend on how you want
your program's behavior to change in that situation. Most of the time
you'll want to use the second technique.
Also note that if you use the second technique, you must check that
[characters length] 0 before you grab character 0. It is entirely
legal for an NSEvent's characters to be empty, and you don't want to
throw an exception because of that.

Table view containing cells with both an image and text
I need a column in my NSTableView with cells that contain both an image and some text. My first inclination is to subclass NSCell and have my subclass manage both a NSImageCell and a NSTextFieldCell. Basically, I would imagine would override: - (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView and have it call drawWithFrame on the internal image cell and text cell with the appropriate frames. Then, assuming I am on the right track, is it also then correct that what - (id)tableView:(NSTableView *)aTableView objectValueForTableColumn: (NSTableColumn*)aTableColumn row:(NSInteger)rowIndex would return is what NSCell's setObjectValue gets called with? Can't think of any reason why this wouldn't be the case... Thank you. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Detecting the Enter Key
I'm certain he means:
Physical key: actual key on keyboard that was pressed (may be
independent of the letter/word/symbol on the key face)
Logical key: this would map to the letter/word/symbol on the key
face, regardless of physical placement on the board

The physical key means (roughly) the switch on the keyboard that
sends an electrical signal with the code 0x04C, which might not
necessarily correspond to a key marked enter on all keyboards. The
logical key is the action performed by that signal, in this case, a
line break.

Newbie. Creating SubViews that aren't associated with NSWindow, or NSPanel?
Hey All, this could be a newbie question, or a somewhat mid-level question. Basically, I don't understand how I can create views that aren't associated with an NSWindow, or NSPanel. Here's a breakdown of what I'm trying to accomplish.. -I have a MainMenu nib. -in that it has the usual 1 window. -On the Window, I have a NSToolbar. -The NSToolbar has 2 buttons (view1,view2) View 1 will be the default. Now what I want to do is show/hide view1/view2 depending on which button you click. What I'm confused about is achieving tab like behavior, without using a tab view. How do I go about create views separately, and attaching them to the NSWindow, based on the toolbar buttons. I'm looking for is some direction. Here's kind of what I was thinking.. option 1. Create multiple NSWindows or NSPanels, for view1,view2. Use the contentView property of those windows to attach to my main window when you've clicked a toolbar button. option 2. Use separate nibs for the views, each nib would be an NSPanel. Then the main bundle loads those nibs in, attaches it's contentView to the main bundle's main view. Is this the right direction?

Re: Date Formatter year input without year display
On Dec 10, 2008, at 10:48 AM, Paul Bruneau wrote: Hi- I ran into a problem with my production scheduling application as the new year approached. In IB I am using a 10.0 date formatter bound to NSDate properties of a model object. I used: %1m/%1d, %1I:%M%p which gave me something like: 12/23, 12:30PM This was used mostly for display, but the user is also able to type into the edit field in order to change the value. As the new year came into play, he might have changed 12/23 to 1/5. My thinking was that if he entered just 1/5 it would assume the current year, which seems to be correct. But I thought if he entered 1/5/2009, then Cocoa would help me out and do the right thing. In fact, even when entering the year explicitly, the formatter still made the data be 1/5/2008. I had to add the year to the formatter string to make it accept the year as input. Is this expected? Is there a good way to only display the month and day, and yet allow the year to be entered if desired? I've yet to find a better way but I accomplished something similar, parsing multiple date formats with one formatter, by making a sort of meta-formatter. Basically define a subclass of NSDateFormatter that references a display formatter and an array of input formatters. I used static instances of the formatters but you could also just change the formatter settings as well. Then override all of the NSFormatter methods passing them on to either the display formatter or iterating through your input formatters (most specific to least specific) until one can successfully parse the input string.

I'd really appreciate some feedback. Views don't need to be contained in a window in the nib. You can drag a view from the library directly into the nib. You can then set up outlets from, for example, File's Owner to these views to reference them later in the code. Depending on the design, all the views may be in the same nib as the window or, if they are likely to be reused in other contexts, each view can be put into its own nib which you'd use NSViewController to load and own.

Starting Cocoa apps from the command line
Hello, I have a Cocoa application that I am compiling in the traditional UNIX manner using Makefiles and I want to be able to invoke it with command-line arguments and without creating/installing it like traditional OSX apps, as in x.app/Contents/MacOS/x. When I tried the usual thing that works on UNIX, compiling to binary and just running it, my application got mouse events but no keyboard events, among other strange things. Is there a way to do this without making some kind of wrapper caller that generates the directory and a script or some such? Or is it wholly frowned upon to do what I'm wanting, and if so, why does it half-work rather than fail with a decent error message?

Re: CoreData -- addPersistentStoreWithType crashing

Core Data triggering an objc_assign_strongCast crash?!
I've suddenly been experiencing a problem where calling - [NSManagedObject validateForDelete:] causes the method to call objc_assign_strongCast, which then mysteriously crashes. The application does not use GC, but the object is properly retained, so it's not that. Has anyone ever seen this before, and if so, what did you do to fix it? Things I've already tried: 1. Running with Guard Malloc turned on (Guard Malloc finds no problems) 2. Running the X86-64 version of the app in addition to the usual X86 version 3. Running with zombies on (the object is not a zombie) I haven't yet tried running it under PPC or PPC64.

Hey Ken and Nick, thanks for the feedback. I have continuing questions if you wouldn't mind. archive them in a nib, load the nib, and then attach them to the window or window's content view. -So I would use a separate nib that contains NSPanels, with the views layed out in that, load the nib, then attach it's content to the main windows content?

You can then set up outlets from, for example, File's Owner to these views to reference them later in the code. -So, by doing this, you don't get to visually see the view in interface builder?

Re: Newbie. Creating SubViews that aren't associated with NSWindow, or NSPanel?
The NSPanels are unnecessary middle men in your case. Rather than using an NSPanel in order to access its contentView, instead create a new standalone view object in IB by dragging in a custom view from the library to the document window (not the canvas). Then double click the view's icon in the document window, and the view will open up in a window. You can then go ahead and lay out its contents, just as you would with a NSPanel's contentView.

Working with a stand-alone view in a nib _does_ let you visually design it. Interface Builder does show it in a window frame when you're editing it, but it isn't really in a window. You can drag a custom view out of the library, or you can copy the content view of a window and then paste it at the top level. You can also drag a window's content view into the library so that the library will have a ready-made plain (non-custom) NSView for your future use.

For some (rare) apps on OS X, staying open is not expected /

This can be done via -

I think it is still correct to invalidate your cell's rect, and have the table redraw (potentially redrawing everything). OK, at least that confirms my observations - I'm not going mad after all! (Or I might be, but not because of this...) I think you should try another approach. Go back to invalidating the rect of the cell that you want to redraw. Essentially, you want one cell to maintain specific state while you are doing something else. Exactly. There is one easy approach to do this, which is to maintain a copy of the cell while you are showing your special menu, and use that cell to draw *just* that one particular row/column. D'oh! Of course. A copy... obvious, now you point it out. General steps: 1. Save off the row/column 2. Copy the cell at that row/column when showing your menu 3. Always return that copied cell from the delegate method: - (NSCell *)tableView:(NSTableView *)tableView dataCellForTableColumn:(NSTableColumn *)tableColumn row: (NSInteger)row AVAILABLE_MAC_OS_X_VERSION_10_5_AND_LATER; else, return [tableColumn dataCell]. 4. Don't update the properties for that row/column in -willdisplaycell 5. Update the colors of that copied cell when your menu changes state 6. Drop the copied cell when your menu goes away. Another approach would be something similar to this great example: http://developer.apple.com/samplecode/PhotoSearch/ .corbin Great, I'll give this a shot. Actually I woke up this morning thinking that I'd need to do something along these lines (isolate the cell being tracked), so sleeping on it really works - I definitely should avoid these 16 hour straight coding sessions... I'll also check out the suggested sample. Thanks! --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

large texts in NSTextView on 10.4
I have to deal with very large texts in a textView , on OS X 10.4. Does anybody now how to implement a subclass of NSLayoutManager that acts like nonContigousLayout on 10.5, so to achieve acceptable performance also on 10.4 ? Which methods should I override?

Countdown With NSTimer - Hours, Minutes, Seconds Remaining?
i believe i painted myself into a corner here... i have a
NSPopUpButton with 3 items. 1 Hour, 2 Hours, 3 Hours. each item has
respected tag numbers 1, 2 and 3. i'm attempting to print out time
remaining but i can only get as far as displaying seconds remaining
with this: NSLog(@%.2d Seconds Remaining, (hoursSelected -
second)); but i would like for the log to output @%.2d Hours, %.2d
Minutes and %2d Seconds Remaining; i can't wrap my head around it,
and i fear that my trying to be as if/else statementless as possible
by using the tag numbers of the PopUp Menu is causing me problems.

Re: Countdown With NSTimer - Hours, Minutes, Seconds Remaining?
If you save off a starting time object you could use NSDateComponents.
NSDate *startDate = /* set at beginning */
NSCalendar *cal = [NSCalendar currentCalendar];
NSCalendarUnit units = NSHourCalendarUnit | NSMinuteCalendarUnit |
NSSecondCalendarUnit;
NSDateComponents *comps = [cal components:units fromDate:startDate
toDate:[NSDate date] options:0];
The resulting comps object will respond to -hour, -minute and -second
messages.

Re: Countdown With NSTimer - Hours, Minutes, Seconds Remaining?
i read in the docs that the use of NSCalandarDate is discouraged
because it's going to be depreciated for OS X 10.6... i'm not really
sure if depreciated means that any code with NSCalandarDate will no
longer function with the new OS or if it will just be considered out
dated...

Re: The thread that starts by NSTask didn't clear up
I appreciate that you give me you hand, Thank you very much, I have solved this questions, and I also learn knowledge that NSTask is just a wrapper around execve(), no threading involved. Thanks. 2008/12/10 Etienne Guérard [EMAIL PROTECTED] OK It seems that in leopard NSTask uses a thread to monitor the launched process, presumably to detect process termination. This thread should disappear shortly after the corresponding NSTask instance is released. Since the launched NSTask is auto-released you need to do one of the following: 1. Install a NSAutoreleasePool somewhere in your loop 2. Use [[NSTask alloc] init] and explicitly release your task when you're done.

I had use threadViewer to note thread count, when go to step that launch application use NSTask, thread count will added, when application quit, the thread didn't stopped, but on tiger this works right I think.

As far as I understand, you use NSTask to launch your application. But this does not imply that a new thread is created to monitor the launched process, unless of course, if you setup your own thread to monitor the process. So I think you assume that NSTask will use a thread but this is wrong. NSTask is just a wrapper around execve(), no threading involved here. and then send Apple event, when application received Apple event , it will quit, usually, the thread starts by NSTask will exit, because the application had quit, so I don't understand this, if use NSTask launch application more times, thread count will always increased, even if application had quit.
