pub fn refresh_pointer_icon()Expand description
Offers the icon the session already holds to the platform again.
A windowing system resets the cursor to its own default on the way back into a window — when the application is activated, or when the pointer crosses in — without telling the application what it drew. Nothing in the hovered region has changed, so no change would be reported and the platform default would stay on screen over a region that names its own cursor. The platform layer calls this at those moments so the next poll re-applies what the region already asked for.
