<p>Suggested alternativ -mouseDown: implementation for dragging</p> <p><b>New page</b></p><div>Why not use something like<br /> <br /> - (void) mouseDown: (NSEvent *) theEvent<br /> { <br /> BOOL isInside;<br /> unsigned int mask = NSLeftMouseUpMask | NSLeftMouseDraggedMask;<br /> <br /> if( nil == target ) return;<br /> <br /> while( [theEvent type] != NSLeftMouseUp )<br /> {<br /> theEvent = [[self window] nextEventMatchingMask: mask];<br /> isInside = [self mouse: [self convertPoint: [theEvent locationInWindow]<br /> fromView: nil]<br /> inRect: [self bounds]];<br /> <br /> switch( [theEvent type] )<br /> {<br /> case NSLeftMouseDragged: // drag<br /> //<br /> // whatever needs to be done while dragging<br /> //<br /> break;<br /> <br /> case NSLeftMouseUp: // drop<br /> if( isInside )<br /> {<br /> //<br /> // whatever needs to be done when button is released<br /> //<br /> }<br /> break;<br /> <br /> default:<br /> break;<br /> } /*switch */<br /> } /* while */<br /> } /* -mouseDown: */<br /> <br /> Looks much cleaner and should be faster.</div>
