Re: Getting Mouse Moved Events

Greg,

Thanks for the reply. My requirements do not fit well into the tracking rectangle solution, unless I make the entire view one rectangle.

Given the restrictions that appears to be my only approach, short of doing my own event dispatching. Would mouse moved be available to an inner event polling loop responding to mouseEntered? I tend to avoid such constructs, preferring to rely on the main event loop, but it might be the right solution to this.

Also the text in the documentation on mouse event dispatching "The NSView selected to receive a mouse event is determined by the NSWindow using NSView's hitTest: method, which returns the lowest descendant that contains the cursor location of the event (this is also the topmost NSView displayed)." makes no mention of having to be first responder. It clearly works that way, but does not make it clear why it works that way. Could I override the NSWindow methods to dispatch to the desired view?

Michael

Mostly I am annoied that the requirement to be first responder exists at all. Having to notify the window that you want these events makes sense from an efficiency point of view, but often (in my cases anyway) I want to track the mouse moved to do highlighting in places where I am NOT the first responder.

Hi Michael,

If you are doing highlighting on mouse over, you might want to look at the documentation for tracking rects and -mouseEntered:, -mouseExited: messages instead of using -mouseMoved:. Using tracking rects requires a bit more setup, but it is an efficient way to handle these kinds of highlighting, and it doesn't require being first responder.

Hope this helps,
- Greg
