Mouse cursor do not update

[horoma]

Hi all,

I have put my Qt Application in a embedded system and I have set up the mouse driver and mouse handler.
In case, I can see the mouse position by log, but actually the mouse cursor do not update.

I am sure that the mouse can move on my system, but the cursor somehow cannot update.

Does anyone know that when/how the Qt draw the mouse cursor? More, how can i force the mouse cursor update?

Thanks
