Animation effect of gif in QPushButton

[santosh.kumar]

Hi,

I have an animated (attached)gif file. I have set this to a PushButton
icon like in the following :-

QPushButton* button = new QPushButton(this);
  button->setIcon(QIcon((":/images/1.gif")));
  button->setIconSize(QSize(128,128));
  button->setFlat(true);

QPushButton* button = new QPushButton(this);
  button->setIcon(QIcon((":/images/1.gif")));
  button->setIconSize(QSize(128,128));
  button->setFlat(true);

To copy to clipboard, switch view to plain text mode 

But I am not able to see the animation effect in the GUI.

Please tell me some body to see animation effect.

Thanks
Santosh
