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 .
- class PySide.QtGui.QX11Info¶
- class PySide.QtGui.QX11Info(other)
Parameter: other – QX11Info Constructs an empty QX11Info object.
Constructs a copy of other .
- static QX11Info.appCells([screen=-1])¶
Parameter: screen – int Return type: int Returns the number of cells 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.
