I have gone through many different threads on this, read the docs
and went over a few example projects. For some reason I cannot
get reordering via drag and drop to work. I have even created a
new project with only a NSTableView with one column and pasted code
from a working example and it still wont work.
My guess is my error is somewhere around the
registerForDraggedTypes method because I cannot even start the
drag. It only start to highlight multiple selections. I dont
fully understand that method and I should also note that all the
example projects are document based projects and mine is not.
Code would really help here.
To get to the point where dragging *begins* you need to minimally do
the following:
1) Have a data source (an object that, in 10.6 and newer, conforms to
NSTableViewDataSource) properly set for your table. I repeat: make
sure your data source is assigned to the object in which you are
implementing your dragging methods.
2) In your data source, return YES from
–tableView:writeRowsWithIndexes:toPasteboard:.
If you do this, you will be able to start a drag (but won't be able to
drop it anywhere yet).
Note what I did not mention:
* Whether the app is document based is irrelevant.
* You DON'T need to call -registerForDraggedTypes:. This method is
used to set which pasteboard types the view potentially _accepts_ from
a drag. If you don't register one or more types, the table view won't
let you drop a row that you are dragging, but it will let you begin a
dragging session.
* You DON'T need to implement anything other than a return in
–tableView:writeRowsWithIndexes:toPasteboard:. Of course, if you
don't you won't actually be storing any pasteboard data, so the drag
will be useless - but the drag will still visually begin.
So, check on your implementation of the two steps listed earlier. You
might consider breaking on
–tableView:writeRowsWithIndexes:toPasteboard: to make sure it's
getting called.
After you have nailed that down and can see a drag begin, you will
need to flesh out the full dragging procedure. In particular:
1) DO call -registerForDraggedTypes: and give it an array of UTIs; for
a table view, this may be a single custom UTI you define for internal
use and which you will use in the dragging methods where required.
2) DO fully implement –tableView:writeRowsWithIndexes:toPasteboard:.
For row reordering purposes, it may be as simple as:
- - (BOOL)tableView:(NSTableView *)tableView
writeRowsWithIndexes:(NSIndexSet *)rowIndexes
toPasteboard:(NSPasteboard *)pboard
{
NSData *data = [NSKeyedArchiver archivedDataWithRootObject:rowIndexes];
[pboard declareTypes:[NSArray
arrayWithObject:MyAwesomeCustomUTIStringThatIDeclaredSomewhere]
owner:self];
[pboard setData:data
forType:MyAwesomeCustomUTIStringThatIDeclaredSomewhere];
return YES;
}
3) DO implement
- -tableView:validateDrop:proposedRow:proposedDropOperation:, most
likely returning NSDragOperationMove for a row reordering operation.
4) DO implement -tableView:acceptDrop:row:dropOperation: to reorder
the rows and/or update the model (if appropriate), typically returning
YES if it's a simple row reordering.
Good luck - feel free to post a link to your sample project if you
can't get it to work.

Shouldn't the instance created using dataWithBytesNoCopy:length:freeWhenDone simply hold the same bytes as the originally provided ones? Presumably you're using 'dataWithBytesNoCopy:length:freeWhenDone:NO', since 'dataWithBytesNoCopy:length:freeWhenDone:YES' would be invalid in the scenario you describe. Right. I'd guess that, with the 'NO' parameter, NSMutableData copies the data anyway. Mutating the data would become treacherous if the underlying memory doesn't belong to the NSMutableData object that's trying to mutate it. That would explain, although the NoCopy is in that case moot then. So, really all you could do is change individual bytes, and you scarcely need subsidiary NSMutableData objects for that -- simple C pointers would do. (Note, however, that you'd be using interior pointers, which would open you up to a range of possible memory management issues, depending on which memory model you're using.) I see. And agree. What are you trying to get the subsidiary NSMutableData objects to do for you that C pointers won't? No - I mean I can do all those things I need to do by laying a set of structs over the array of bytes I receive within the original NSMutableData instance. But what I tried to achieve was to do it somewhat more OO, although sharing the payload between various instances seems to be contradicting it ;-) And I also wanted to minimise the overhead of passing and copying large amounts of data around in order to do the manipulations, while at the end having a need to reconstruct the original stream (file format) from multiple objects.

How do I get that button cell to send it's action and have no row selection

See the 'tableView:shouldTrackCell:forTableColumn:row:' delegate method.
The reference documentation for this method includes this discussion:
Normally, only selectable or selected cells can be tracked. If you
implement this method, cells which are not selectable or selected can be
tracked, and vice-versa.
For example, this allows you to have an NSButtonCell in a table which does
not change the selection, but can still be clicked on and tracked.
Does that sound relevant to your situation?

NSTableView data source issue - code moving from xcode 3 to xcode 4
Hi There For a long time ( in xcode 3 ) when I want to access a table view data source ( in the sub class code for the table view ) I simply called [self dataSource] I would then call methods declared and implemented on the class which I new to be the datasource. This worked fine. In xcode 4 ( sdk 10.7 ) the compiler throws a semantic warning when I do this. It complains that the return value from [self dataSource] is ignorant of the methods I am calling on it. I have found a solution in overriding the dataSource method in my table view subclass and simply returning [self dataSource] cast to the class which I know the datasource to be. This feels evil. Is there a nicer way to do this ? Peter ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

You will have to make sure that DataSourceClass declares it complies with

Nothing. It's only [NSDate -dateWithTimeIntervalSinceNow:FLT_MAX] which

It's not, at least not on 10.6 with Xcode 3.2.5. This program...
#import Foundation/Foundation.h
int main (int argc, const char * argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
NSLog( @distantFuture: %@, [NSDate distantFuture] );
NSLog( @FLT_MAX: %@, [NSDate dateWithTimeIntervalSinceNow:FLT_MAX] );

I think you'll find distantFuture much less buggy than your solution,
seeing as how it isn't going to overflow or run into boundary
situations.

Screen Coordinates of Menu. Use CTM? (was: Give menu keyboard focus)
I changed the subject line because if I could just get the screen coordinates
of my Status Item, my kludge for giving it keyboard focus looks like it will
work.
NSMenu inherits from NSObject, and as far as I can see give no clue regarding
its location on the screen. NSStatusItem and NSStatusBar are likewise mum.
However, the status item has an image. I subclassed NSImage, found that
-drawInRect:fromRect:operation:fraction:respectFlipped:hints: is invoked. From
reading the Cocoa Drawing Guide, it seems that the tx value of the current
transformation matrix when this method is running is the x-coordinate that I'm
looking for. So I subclassed NSImage…
@implementation MyLocatableImage
- (void)drawInRect:(NSRect)dstSpacePortionRect
fromRect:(NSRect)srcSpacePortionRect
operation:(NSCompositingOperation)op
fraction:(CGFloat)requestedAlpha
respectFlipped:(BOOL)respectContextIsFlipped
hints:(NSDictionary *)hints {
NSGraphicsContext* nsGraphicsContext = [NSGraphicsContext currentContext] ;
CGContextRef aContext = [nsGraphicsContext graphicsPort] ;
CGAffineTransform ctm = CGContextGetCTM(aContext) ;
NSLog(@The ctm: %f %f %f %f %f %f, ctm.a , ctm.b , ctm.c , ctm.d , ctm.tx

[super drawInRect:dstSpacePortionRect
fromRect:srcSpacePortionRect
operation:op
fraction:requestedAlpha
respectFlipped:respectContextIsFlipped
hints:hints] ;
}
@end
Unfortunately, the matrix elements are NSLogged as:
1.00 0.00 -0.00 1.00 0.00 22.00
which is obviously not what I'm looking for, since the the x-coordinate of my
status item is about 850.
The two 'Rect' parameters of that method give similar useless local coordinates.
Is there any way to get the global/screen coordinates of a menu, an

Here's what I get: Here's what I get: http://a3.l3-images.myspacecdn.com/images02/127/4715903defac43d196c873a29fd6527d/l.jpg Here's what I wish I could get: Here's what I wish I could get: http://a1.l3-images.myspacecdn.com/images02/148/6699adf99ae949428b97cfa74ae9e1a9/l.jpg The following code shows the basics of what I am writing: m_attribs is a NSMutableDictionary ... font = [NSFont fontWithName:@Geneva size:10]; [m_attribs setObject:font forKey:NSFontAttributeName]; ... [m_string drawAtPoint:NSMakePoint (0,0) withAttributes:m_attribs]; Geneva font gives the problem shown in the above image. Other fonts such as Helvetica are fine. What can be missing to make the string drawn with enough space between the first two characters and the rest? I tried to set NSFontFixedAdvanceAttribute, but then I get an unnatural spacing between all characters.

Unfortunately, the built-in F8 keyboard shortcut to Focus on Status Items only cycles through the *Apple* status items. (Filed a few weeks ago: Apple Bug ID #10122120). For this reason, any menu item with a name can be assigned a keyboard shortcut in OS X System Preferences by the user. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Xcode 3 to 4 - CoreData in IB
Back in Xocde 3 you could drag an entity into IB. With Xcode 4 you can no longer do this. I have found a way to do the exact same thing in IB but miss the ease of use of dragging an entity into IB. Does anyone know if the IB team will be bringing this back in future releases of xcode? PS - I currently have xcode 4.1 GW ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

You could use [NSMenuItem setView:] with a temporary view which would presumably be hooked up to the underlying window internally, grab its window, then set it back to nil??? A hack, but not as bad as the original one :) --Graham On 10/10/2011, at 4:41 PM, Jerry Krinock wrote: On 2011 Oct 09, at 19:57, Seth Willits wrote: The status icon/view in the menu bar is in a window.
