Hi all,
So for some days now I've been trying to make a custom NSActionCell that
works in an NSTableView that in turn uses Cocoa Bindings.
Starting from mmalc's ClockControl example, I now have it working for
simple cases.
Basically, I'm trying to implement a cell version of NSColorWell.
This works:
- (BOOL)startTrackingAt:(NSPoint)startPoint
inView:(NSView *)controlView
{
NSColor* colour = create random colour
[self setObjectValue:colour];
}
This doesn't:
- (BOOL)startTrackingAt:(NSPoint)startPoint
inView:(NSView *)controlView
{
NSColor* colour = create random colour
[self performSelector:@selector(setObjectValue:)
withObject:colour
afterDelay:0.0
}
There seems to be something 'special' about the various mouse tracking
methods. It seems that if I change my cell's objectValue outside of the
mouse tracking methods, that the TableView does not pay attention (and
does not update my model).
I want to change my cell's objectValue in response to an action from the
NSColorPicker.
Is there a way to 'poke' the tableview so that it notices such a change?
Thanks,
--
