C#, Mouse Event outside the Form

8 Apr 2012 by Sergey Alexandrovich Kryukov

Outside mouse events might be dispatched to some other application, so they might not logically exist for a regular .NET application. My first response would be this: you don't really need it. The behavior you want would contradict the accepted UI model of the OS; it would also drives your...

How to disable mouse down outside WPF Window?

29 Apr 2015 by Sergey Alexandrovich Kryukov

The question makes no sense: "mouse down" is something the user does with the physical mouse device, it cannot be disabled. And if you could disable moving the mouse pointer to any area of the screen, it would greatly damage the usability of the whole system. It would be hard to invent more...

How to hide a button control on mouse over in WPF

13 Feb 2012 by Christian Graus

I don't see any code here to set the visibility. I don't see any triggers to catch events. I see no code at all to do what you want. I would use events and write code to set the visibility at first, that's easier to debug and follow than triggers. The Visibility property works just fine.

Mouse Click event capturing

18 Oct 2012 by Sergey Alexandrovich Kryukov

You need to capture all such events, because I think, Windows Hook API does not give you other options. But, in handling of this event, you need to discriminate the further action by the coordinates of the click. Just do nothing if the click goes out of the clipping area of your notification...

Mouse Click event capturing

18 Oct 2012 by Dave Kreskowiak

So you want your application to "eat" the mouse click so it doesn't go to the next hook in the chain. In that library, there should be a call to a function called CallNextHookEx. That function call has to be skipped if you want your app to "eat" the mouse click so the system doesn't see it.
