NSButton Up/Down Events

[Brad Carter]

I'm new to the list and very new to Cocoa and programming in  
general.  My only programming experience was Basic about 20 years ago  
when my father put me in classes.  I have just finished one book on  
Object C and the other, Cocoa Programming for Mac OS X.

I have an AppleScript Studio app that I'm rewriting in Cocoa.  The  
app sends a curl command with a URL to a box that does relay closures  
and that in turn controls the pan/tilt of a video camera.  I have the  
AppleScript set up using mouse down/up events so when the button is  
pressed and held down the camera pans, when the button is release the  
panning stops.

I can't figure out how to do this in Cocoa.  I have subclassed  
NSButton and overridden mouseDown: and mouseUp and display this to  
NSLog confirming my success.  How do I tell what button was pressed  
in the mouseDown: method?  I can't find anything in NSEvent that  
would hint that this info would be passed as an NSEvent.  Here's my  
code below.

Thanks,

Brad

- (void)mouseDown:(NSEvent *)event
{
     NSLog(@"down");
     [super mouseDown:event];
     [self mouseUp:event];
}

- (void)mouseUp:(NSEvent *)event
{
     NSLog(@"up");
}
