Detailed Description

The QX11Info class provides information about the X display configuration.

The class provides two APIs: a set of non-static functions that provide information about a specific widget or pixmap, and a set of static functions that provide the default information for the application.

Warning: This class is only available on X11. For querying per-screen information in a portable way, use QDesktopWidget.
