The Finger Paint example shows the use of a touchscreen with a custom widget to create a simple painting application.

This example was specifically designed to work with a touchscreen, using QTouchEvent instead of QMouseEvent to handle user input over the custom widget. As a result, it is not possible to draw with the mouse cursor.
