Transparent button icon

[alenn.masic]

Hi all

I have transparent button icon, it's transparent when I open it with picture viewer but when I import it in Qt and set it as button icon it's not transparent anymore. How to fix this.

I'm setting icon like this:

QPushButton button = new QPushButton(QIcon("image-path"), "Button-text", this);

How do you know it is not transparent, are the transparent areas being rendered white?

I know because I'm supposed to see image behind button. And yes, it's rendered white.
