I was wondering if there is a straight forward away to know if the
mouse is on the border of a view? I know how to detect if the mouse
enters a view area by using NSTrackingArea - but how can I tell if
the mouse is on a border? I would like to replicate iCal's behavior
where a user can modify an event on the calendar by clicking on the
edge of the appt. rectangle and dragging it.
Assuming you just care when the mouse clicks, you could test for it
like this.
- (void) mouseDown:(NSEvent*)theEvent
{
NSPoint localMouseLocation = [self convertPoint:[theEvent
locationInWindow] fromView:nil];
NSRect nonBorderRect = NSInsetRect([self bounds], 4, 4);
if (NSPointInRect(localMouseLocation, nonBorderRect))
{
// click inside the non-border portion of the view
}
else
{
// click in the view's border
}
}
