I just want to animate the paint function with the drawEllipse, and now the whole thing is moving to the background.
-
Paint functions draw background and ellipse.
I only want to give an animation effect to an ellipse, so how can I distinguish and add attributes? -
@IknowQT Does your class have a "circle" property?
You need a property in your class which is then animated. In the setter for that property you can call update() to trigger paintEvent where you use the property value to draw your ellipse.
