Generally you'd use the mouseDown to get when and where the drag
started (may have). Then use the mouseDragged to track where the
mouse is dragging to. Then on mouseUp you know it's done. Tracking
area is only valid if a tracking rect you installed generated the event.

What is the typical information that people get from a mouse dragged
event?
I have the following:
- (void) mouseDragged:(NSEvent*)event
{
NSPoint eventLocation = [event locationInWindow];
NSPoint center = [self convertPoint:eventLocation fromView:nil];
m_controller->left_mouse_dragged(center.x, center.y);
}
I tried getting the tracking area but ended up with an assertion
error during runtime.
Do folks somehow get the direction of the drag, size of the
rectangle, starting x,y, and etc.?
