Qt是否需要在Linux上预安装的窗口管理器？

Question

I'm working on a GUI application with Qt on Linux. The operating system only provides the X Server and the prerequisites to run a Qt application. There is no desktop environment like GNOME, KDE, etc. installed yet. There's no window manager neither.

So my question is: does Qt require a preinstalled window manager (like KWin, Compiz, Metacity, etc.) or is it possible to write a Qt application that communicates with the X Server directly? I'm aware of the fact that the latter one possibly drives me crazy due to the effort I'd have. However, due to limitation of resources it could be an option.

Thanks in advance for your help!

No, Qt doesn't require a window manager when running under X11. You will have to manage your own windows, though! That means that you'll have to manage the Z order of windows, dragging windows on the screen, minimization/maximization if you need such, etc.
