animate buttons

[kenouz1234]

Hello,
I would like to animate my 4 QPushButton so when I click on button1 the state1 will be trigger, when I click on button2 this trigger state2 and the click on button3 trigger state3.

I tried and tried to do this but unsuccessful

my code is based on this Qt example: http://doc.trolltech.com/4.7/animation-moveblocks.html

please help me to do this and if possible simplify me the code if it's simplifiable because I don't need the random state triggering as in the above Qt example
