    Re: Very large images as background

    I was thinking about splitting the image as well. But the large image splitted will cost the same amount of memory. I mean, 100 MB is 100MB if I try one image o 100 images of 1MB.

    Here it says

    4.7.0. It also introduces OpenGL support for Symbian.

    Re: setCentralWidget problem

    In the end I'm mixing both. A form for the normal-style forms, and QGraphicsProxyWidget if I just want few buttons or not complicated widgets. Everything under stackedwidgets.

    Re: setCentralWidget problem

    I had it before. But nothing changes.

  21. Re: [moved] Does anyone have example project?

    If I were you I'd start learning Qt, not trying to understand a medium level example from the beginning.
