Re: NSControl subclass and accessibility
Accessibility for NSControls is handled by the NSCell inside it, not the
NSControl. Good luck.

NSControl subclass and accessibility
Hi,
I'm having trouble getting a custom NSControl subclass properly visible with
regards to accessibility.
If I implement my custom control as an NSView subclass and adopt the
NSAccessibilityButton protocol, I can "see" my custom control with
accessibility inspector when I hover above it.
If I take the same class but make it a subclass of NSControl, I'm not able to
"see" my control using accessibility inspector when hovering above it. It is
detecting something because I can see that when I hover in the containing view,
I can see the window ui element, but when I hover above the control itself, I'm
only seeing the "app" element. Also, when I inspect the containing view I can
see my control listed there and I can access it and perform the action.
I feel like I'm missing something obvious. Any ideas?
Here's my code, If I replace NSControl with NSView, it seems to work great.
@interface MyFancyButton : NSControl
@end
@implementation MyFancyButton
- (void)drawRect:(NSRect)dirtyRect ...
- (void)mouseDown:(NSEvent *)event ...
- (void)simulateClick ...
- (nullable NSString *)accessibilityLabel
{
return @"my_label";
}
- (BOOL)accessibilityPerformPress
{
[self simulateClick];
return YES;
}
@end
Thanks in advance,
Eyal Redler
