Hi,

is there any possibility to create a pfPipeWindow in Performer without
showing it? I know that there is the pfWindow::openNewNoPort() function.
But this does not really help since I want to create the render window
(and not any window) and show it later (I perform texture downloads and
this requires the render window to exist I think). At the moment I open
the window with pfWindow::open() and use X functions to unmap it
immediately:

        m_pPipeWin->open()

        Display* xdisplay = pfGetCurWSConnection();
        Window xwin = m_pPipeWin->getWSWindow();

        XUnmapWindow(xdisplay, xwin);
        XSync (xdisplay, True);

The effect is that the window appears and disappears immediately. Then I
can perform texture downloads etc. and map the window if I need it. It
works but I would be glad if I had a possibility to avoid the flashing
window...

Thanks for any comments,
Yves
