How to get the QIcon fileneme in use.

[gt.beta2]

Hello

I have buttons that i want to change the icon image file depending on some situations.
I use:

ui->objectname->setPixmap(QPixmap(":/prefix/alias"));

ui->objectname->setPixmap(QPixmap(":/prefix/alias"));

To copy to clipboard, switch view to plain text mode 

Is the a way to read the resource name into a QString (for instance)?

Thanks
