Yeah, I need to look at that original message. I’ve been doing iOS stuff for
years and so OS X stuff is a bit foreign to me. I only hit the OS X stuff
intermittently - i.e. when my team needs some specific UI stuff which is ironic
in a way. We’re all iOS developers learning OS X.
So, can you help me understand what the below code does? So I have this class:
@interface MiniTabBarButton : NSButton
@property(strong) NSTabViewItem *tabViewItem;
@end
and we create the button:
NSImage* iconImage = [(id <MiniTabBarItem>)tabViewItem.identifier icon];
[iconImage setTemplate:YES];
newButton.image = iconImage;
So with that in mind, remember I don’t even really know what NSButton provides
(again, I understand UIButtons really well - and I do have some understanding
of NSButton custom drawing to some degree as I did write a subclass for the
checkbox style:
@interface CalendarFilterCheckbox : NSButtonCell
BUT, in this case I’m just trying to get the glow on selected images, so when I
look at the code below all I see is that we’re getting the bitmap and drawing
it. I’m not understanding how that gets a glow.
Sorry for being dense, but I do learn quickly. I just am like a blind man at
first.
