How to hide the mouse cursor

[brabebhin]

I've been trying to wrap my head around this one: how to hide the mouse cursor? this is pretty straigthforward on both UWP and win32 but winUI 3 seems to have no way of doing this.

To put it simply, WinUI 3 applications are desktop (Windows API/Win32) applications. WinUI 3 is basically a library/framework, therefore it needs an existing process model to work on. So use the Windows API method of hiding the cursor.

Yes, i suspected as much, however, I'd wanted a nice way of doing it with winui3 APIs

It can be done with "set_ProtectedCursor" (System.Reflection)
A test by disposing the cursor of "Test" Button to hide it when I click on "Click" Button :

Wouldn't that be the ProtectedCursor that's available in UI elements? What value are you setting?

I just set the basic Microsoft.UI.Input.InputSystemCursorShape.Arrow cursor
Then I called Dispose() to destroy/hide it (it was the idea of someone else in another thread...)
(can also be done with an empty cursor (just transparent pixels), but needs more code)

Great idea with the transparent pixels, this really never crossed my mind. It may actually fit my use case better than the Dispose approach.
