Member Function Documentation

◆ changeCursor()

void QEglFSKmsGbmCursor::changeCursor ( QCursor * windowCursor,
QWindow * window )
overridevirtual

This method is called by Qt whenever the cursor graphic should be changed.

Implementation of this method is mandatory for a subclass of QPlatformCursor.

windowCursor is a pointer to the QCursor that should be displayed.

To unset the cursor of window, \nullptr is passed. This means window does not have a cursor set and the cursor of a the first parent window which has a cursor explicitly set or the system default cursor should take effect.

window is a pointer to the window currently displayed at QCursor::pos(). Note that this may be \nullptr if the current position is not occupied by a displayed widget.

Implements QPlatformCursor.
