Description

The XClearWindow() function clears the entire area in the specified window and is equivalent to XClearArea(display, w, 0, 0, 0, 0, False). If the window has a defined background tile, the rectangle is tiled with a plane-mask of all ones and GXcopy function. If the window has background None, the contents of the window are not changed. If you specify a window whose class is InputOnly , a BadMatch error results.

XClearWindow() can generate BadMatch and BadWindow errors.

Diagnostics

BadMatch Some argument or pair of arguments has the correct type and range but fails to match in some other way required by the request.
BadWindow A value for a Window argument does not name a defined Window.
