OK, sorry, I found where was the problem : I forgot to subclass - (BOOL)isOpaque on my NSButton subclass so that it returns NO (my NSButton is partially transparent).

Hi list !


I'm implementing my own NSButton subclass, currently only drawing a string, and have a strange problem when I click on my button : each time I click on my button, the string appears darker, just like if it was drawn above itself again and again !


Here is the only thing I have subclassed in my NSButtonCell subclass (none my NSButton subclass method has been subclassed for the moment) :


- (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView { [self drawInteriorWithFrame:cellFrame inView:controlView]; }

- (void)drawInteriorWithFrame:(NSRect)cellFrame inView:(NSView *) controlView
{
[[self title] drawInRect:cellFrame withAttributes:nil];
}




It was just supposed to be a test, that's why it is so simple. But even with such a simple code, it doesn't work as expected.


I don't understand why the string draw above itself each time I click on the button. Is there something I should had to erase the previous content of the cell ?




Thanks,


Eric. _______________________________________________ Do not post admin requests to the list. They will be ignored. Cocoa-dev mailing list (email@hidden) Help/Unsubscribe/Update your Subscription:
