My class is a subclass of NSImageView
At the moment I am able to receive left mouse drag...
However I get no right mouse or scroll wheel input....
I am unsure from the documentation if the wheel input comes with a down event...
I suspect that it is because I have not called <x-tad-bigger>setAcceptsMouseMovedEvents</x-tad-bigger>
- (void)mouseDown:(NSEvent *)theEvent
{
}
- (void)mouseDragged:( NSEvent * )theEvent
{
float dx, dy;
switch ([theEvent type])
{
case NSLeftMouseDragged:
NSLog(@"Left Mouse!");
break;
case NSRightMouseDragged:
NSLog(@"Right Mouse!");
break;
case NSScrollWheel:
NSLog(@"Scroll Wheel");
break;
}
<x-tad-bigger>- (void)rightMouseDown:(</x-tad-bigger><x-tad-bigger>NSEvent</x-tad-bigger><x-tad-bigger> *)</x-tad-bigger>theEvent
Generates a compiler error...
error: parse error before `NSEvent'
My conclusion is that NSImageView doesn't handle right mouse buttons or scroll wheels...
but I could be wrong...

I have a few questions about mouse input:
1) How do you get the mouse wheel?

Link to above also exists in the documentation for NSEvent.
