semitransparent wigets

here is the code for semitransparent widgets on windows !with control elements!.

the class works very simple:

1. Set the Widget to Layered Window, which activates alpha blending.
2. initialise a QPixmap with a semi-transparent picture
3. Draw the control elements into the Pixmap
4. Render the Pixmap onto the Widget

RE: semitransparent wigets

Hi!!

Could this be used for Linux/X11 too? cause i really need to do this... and i am looking and reading a lot for it... but still with no luck

So... what i need is exactly as that example, i have a semi-transparent png pixmap and i want that to the background of my app and see through it my desktop.
Like, superkaramba applets.

Thanks!!

Cheers.
