I am making a QT program which wil be deployed in a debian 9 . This linux os was installed WITHOUT a desktop !
So ,there are some wired things happen about my Qt app's behavior.
Today , I try to set a qdialog to transparet by rewrite the paintEvent function . I constructed a qpainter ,and set the alpha as 0 , but the transparent part show as black .
what's the problem ?
what windows manager are you then running ?
And is it still X11 ?
