C# WPF Bring element topmost (even over mouse)?

Question

Hi Guys, I'm working on a project where I'm making an element(or image) follow the mouse on certain events. However, it does block the mouse from other objects preventing it from triggering mouse over or down events. I'd like to know if there's a way around this or even if it's possible to place an element OVER the mouse cursor so it won't block it.

I honestly haven't seen one implemented but it's worth asking than cropping the image(gif animation with 61 frames) into 4 parts(244 images >.<) so the mouse won't be obstructed.

Thanks

Answer 1

I think that if you create a “hole” inside your element (a single pixel would be enough), then the mouse messages will be sent to other objects. Check if this article helps: http://chriscavanagh.wordpress.com/2009/03/16/wpf-rounded-corners-and-holes/.

Alternatively consider making custom cursors.

Answer 2

The image I'm placing in the mouse is a GIF animated through C# code. It's in PNG and unfortunately, transparency in the image doesn't help to I might just crop each 61 images into 4(top, bottom, left and right) leaving a hole in the middle. I did try making my own cursor. Unfortunately, the max is 48px but I need it at 100px.

Hi LaurenceDCM,

I agree to use your own custom cursor should be the best choice for you. But I don't understand what you said cursor's max size is 48px. Do cursor size with this kind of limitation?

You can just use this tool to convert .png image to .cur files, then use it like this.Cursor = yourcursor.cur to achieve your goal.

The idea from this post:http://social.msdn.microsoft.com/Forums/ar/wpf/thread/a58eb8b1-1100-48d9-aaa6-7534f041fc82

Hope it helps.

Have a nice day.

Hi. I did resort to using that tool and just use a 48x48 cursor instead. However, if I use that code, "this.Cursor =......", the cursor is 32x32. How do make it use the 48x48 variant also present in the .ICO file instead? Thanks a lot by the way.
