Checking if NSButton is down on drawRect

Question

I would like to check if my custom NSButton is currently in a pressed state (the user is clicking down on it) in my custom drawRect method. Something like this:

- (void)drawRect:(NSRect)dirtyRect{
    if ([self buttonIsInPressedState]) {
        [[self alternateBGImage] drawInRect:dirtyRect fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:1.0f];
    }else{
        [[self BGImage] drawInRect:dirtyRect fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:1.0f];
    }
    [super drawRect:dirtyRect];
}

How would you check a thing like that? Is it possible?

SOLUTION

I ended up checking the mouseDownFlags on the buttons cell. Don't know if it's the "right" way to do it, so let me know if you have a better suggestion:

- (void)drawRect:(NSRect)dirtyRect{        
    if ([self.cell mouseDownFlags] == 0) {
        [[self BGImage] drawInRect:dirtyRect fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:1.0f];
    }else{
        [[self alternateBGImage] drawInRect:dirtyRect fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:1.0f];
    }

    [super drawRect:dirtyRect];
}

Answer 2

I solved this by checking [self isHighlighted].

Answer 3

I don't think "drawRect:" is the right place to try to catch this.

You can subclass NSButton and then override either mouseDown: or setState: (looking for "NSOnState", which signifies the button is either selected or being pressed on).

I've tried self.state, but it only works for wether the button is "On" or "Off"! So the button is "On", once I've pressed it down AND released it. I want to check for if the use is CURRENTLY pressing down. MouseDown is also an option, but I can't get mouseUp to work for some reason. – Bondage

Answer 4

if([pBtn state]==NSOnState){
   NSLog(@" button Pressed ")
}else{
   NSLog(@" button not pressed ");

}

Can you make use of Push button, its basically a toggle button, perhaps you can get what you want to achieve.. – Greenock

I tried. Doesn't work. I ended up doing the above. Let me know if you have a better solution. – Bondage
