Hi,

As far as I know there are two ways to do it. One way to implement "google-maps" like button is first using regular QT's QPushButton and playing it's css like padding, border etc. Secondly, you may implement your own QPushButton like;
Qt Code:
  1. MyPushButton: public QPushButton {...}
To copy to clipboard, switch view to plain text mode 
and reimplement drawControl() method.

I suggest you to go through with the first method since latter one is far difficult to implement
