Re: Handling mouse events on transparent window conditionally
I'm shooting off the cuff here. But try setting up a tracking area that matches your "active" rectangle. When the mouse enters the tracking area, setIgnoreMouseEvents:NO, when the mouse exits the tracking area setIgnoreMouseEvents:YES. -raleigh On May 31, 2011, at 1:30 AM, Ken Thomases wrote: > On May 31, 2011, at 1:33 AM, Deepa wrote: > >> I am developing an Desktop application in which I should be able to take >> mouse events on transparent window.

The Mac OS X Window Server has to decide where to route events. It is a process outside of any particular application. Once it has picked which window (and therefore application) will receive an event, that's the end of the matter. That application chooses how to respond (including, possibly, doing nothing), but the event won't be delivered to any other application. You can't dynamically choose to pass an event along to the "next" application. (You could try to approach this using CGEventTaps, but I doubt you'd achieve anything satisfactory.) The better approach is to use multiple transparent overlay windows. If you need to make a frame that accepts mouse events around a rectangular area that does not, you may need four transparent windows for the frame and, if necessary, one for the interior rectangle. You can use child windows (-[NSWindow addChildWindow:ordered:]) to make sure the windows move together.

Handling mouse events on transparent window conditionally
Hi, I am developing an Desktop application in which I should be able to take mouse events on transparent window. But, transparent NSWindow does not take mouse events. So, I have set setIgnoreMouseEvents to NO which allows the transparent window to take mouse events. I have the problem in the following scenario: There is dynamically created rectangular shape on this window. The transparent window should not take mouse events in this region; it should be delegated to the window (of some other app) that is present behind this shape. For this purpose, if the mouseDown event is inside the shape I am setting setIgnoreMouseEvents to YES. Now, if the user performs mouse events in the area outside the shape the transparent window should take the event. Since, setIgnoreMouseEvents is set to YES, window does not take mouse events. There is no way to identify that mouseDown event has occurred so that I can set setIgnoreMouseEvents to NO. Could someone suggest me some best method to handle mouse events on transparent window?
