Translucent frameless window problem on Kubuntu

[superpacko]

I see what u mean. The window also loses all the effects of dragging windows, applied on window manager config. I tried running a normal program on kubuntu, removing borders with the window options, and the same happened, dragging effect of windows disappeared.

Is there anyway of letting the window manager know about our frameless window, in order to use the translucency, without loosing all desktop effects?

Don't disable the frame. You can try masking it out (using setMask) however I have no idea whether kwin will be able to detect the mask.

I dont really know how to use the masking or paint methods...
Is there any tutorial or guide for masking actions and use of QPixmaps? im interested in changing widget's shape and making transparent areas, but i cant find a tutorial or examples to that. That would be pretty usefull!

thanks for your help!

Open Qt Assistant (or Qt Creator help pane), go to "index" tab and type in "setMask".
