int QX11Info::appDepth ( int  screen = -1  )  [static]

Returns the color depth (bits per pixel) used by the application on the given screen.

The screen argument is an X screen number. Be aware that if the user's system uses Xinerama (as opposed to traditional X11 multiscreen), there is only one X screen. Use QDesktopWidget to query for information about Xinerama screens.
