Hello all,
I have a subclassed NSImageView that is a drag source and a drag destination. I
am trying to have an NSTrackingArea so that when the drag out of the image view
leaves they window I can update the cursor to indicate deletion of the item - I
am thinking of the cursor that looks like an explosion cloud.
When I log my tracking area it tells me it's "pending install", and I never get
any of the expected mouse-move messages.
This snippet is in mouseDown on the image view:
NSTrackingAreaOptions options = NSTrackingMouseEnteredAndExited |
NSTrackingEnabledDuringMouseDrag | NSTrackingActiveAlways;
NSTrackingArea *trkArea = [[NSTrackingArea alloc] initWithRect:[[self window]
frame] options:options owner:self userInfo:nil];
[self addTrackingArea:trkArea];
[self updateTrackingAreas];
NSLog(@"trkArea: %@", trkArea);
I am running out of ideas what to try - any help would be appreciated.
Thanks,
Rainer
