NSButton Up/Down Events

[Jonathan Toolan]

Brad,

I think what you're looking for is "type":

From
http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/
Classes/NSEvent_Class/Reference/Reference.html#//apple_ref/occ/instm/NSE
vent/type

NSEventType which = [event type];

Returns the type of the receiving event.

- (NSEventType)type
The type will be one of the following:

      NSLeftMouseDown
      NSLeftMouseUp
      NSRightMouseDown
      NSRightMouseUp
	... Etc ...

But I could be wrong. :)

Hope that helped.

Jonathan

Subject: NSButton Up/Down Events

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");
}
