The right place to change the image of the cell would be in the
outlineView's delegate method:
- (void)outlineView:(NSOutlineView *)outlineView willDisplayCell:
(id)cell forTableColumn:(NSTableColumn *)tableColumn item:(id)item
try [[cell image] name] to get the name of the image

Hi all,
I'm trying to develop an application that uses an OutlineView in
which it
displays items like a disclosure triangle, then one checkbox, then a
text
field int the same column. For that I gone through the
DragNDropOutlineview example provided with Xcode. Then I copied the
ImageAndTextCell class and uses two images, one is checked and other
is
unchecked. Now the application works with showing one image.I want to
change the image when clicking on it. How can I do that ?. In which
method
I want to write the code ?
In outlineViewSelectionDidChange method I wrote some code but it
faild.
When I taking the information about image like:
id cell = [[[OutlineView tableColumns] objectAtIndex:0]
dataCellForRow:[OutlineView selectedRow]];
id info = [cell image];
NSLog(@" %@",info);
It writes the log like:cell NSImage 0x17d8a0 Name=checkbox_click
Size={13,
13} Reps=(
NSBitmapImageRep 0x17e0c0 Size={13, 13}
ColorSpace=NSCalibratedRGBColorSpace BPS=8 BPP=32 Pixels=13x13
Alpha=NO Planar=NO Format=1 CGImage=0x17ded0.
How can i get the Image name only ?
Thanks in advance
