Qt animation + button bouncing up

[Kewal]

Hi all,.
I am new to animations and I was trying to animate a button which bounces up with any easing curve available probably if i can understand how to bounce the icon in the Qtoolbutton I can modify it to my taste, but have tried to make the button bounce up but not able to achieve because the animations always seems to work from point x to point x1 but not in the lateral axis.
Is there anyway or sample app which demonstrates this from which i can draw some idea?
