ARGUMENTS

       attributes
                 Specifies the structure from which the values
                 (as specified by the value mask) are to be
                 taken.  The value mask should have the appropri-
                 ate bits set to indicate which attributes have
                 been set in the structure.

       background_pixel
                 Specifies the pixel that is to be used for the
                 background.

       background_pixmap
                 Specifies the background pixmap, ParentRelative,
                 or None.

       w         Specifies the window.

       colormap  Specifies the colormap.


DESCRIPTION

       Depending on the valuemask, the XChangeWindowAttributes
       function uses the window attributes in the XSetWindowAt-
       tributes structure to change the specified window
       attributes.  Changing the background does not cause the
       window contents to be changed.  To repaint the window and
       its background, use XClearWindow.  Setting the border or
       changing the background such that the border tile origin
       changes causes the border to be repainted.  Changing the
       background of a root window to None or ParentRelative
       restores the default background pixmap.  Changing the bor-
       der of a root window to CopyFromParent restores the
       default border pixmap.  Changing the win-gravity does not
       affect the current position of the window.  Changing the
       backing-store of an obscured window to WhenMapped or
       Always, or changing the backing-planes, backing-pixel, or
       save-under of a mapped window may have no immediate
       effect.  Changing the colormap of a window (that is,
       defining a new map, not changing the contents of the
       existing map) generates a ColormapNotify event.  Changing
       the colormap of a visible window may have no immediate
       effect on the screen because the map may not be installed
       (see XInstallColormap).  Changing the cursor of a root
       window to None restores the default cursor.  Whenever pos-
       sible, you are encouraged to share colormaps.

       Multiple clients can select input on the same window.
       Their event masks are maintained separately.  When an
       event is generated, it is reported to all interested
       clients.  However, only one client at a time can select
       for SubstructureRedirectMask, ResizeRedirectMask, and
       ButtonPressMask.  If a client attempts to select any of
       these event masks and some other client has already
       selected one, a BadAccess error results.  There is only
       one do-not-propagate-mask for a window, not one per
       client.

       XChangeWindowAttributes can generate BadAccess, BadColor,
       BadCursor, BadMatch, BadPixmap, BadValue, and BadWindow
       errors.

       The XSetWindowBackground function sets the background of
       the window to the specified pixel value.  Changing the
       background does not cause the window contents to be
       changed.  XSetWindowBackground uses a pixmap of undefined
       size filled with the pixel value you passed.  If you try
       to change the background of an InputOnly window, a Bad-
       Match error results.

       XSetWindowBackgroundPixmap can generate BadMatch,
       BadPixmap, and BadWindow errors.

       The XSetWindowBorder function sets the border of the win-
       dow to the pixel value you specify.  If you attempt to
       perform this on an InputOnly window, a BadMatch error
       results.

       XSetWindowBorder can generate BadMatch and BadWindow
       errors.

       The XSetWindowBorderPixmap function sets the border pixmap
       of the window to the pixmap you specify.  The border
       pixmap can be freed immediately if no further explicit
       references to it are to be made.  If you specify
       CopyFromParent, a copy of the parent window's border
       pixmap is used.  If you attempt to perform this on an
       InputOnly window, a BadMatch error results.

       XSetWindowBorderPixmap can generate BadMatch, BadPixmap,
       and BadWindow errors.

       The XSetWindowColormap function sets the specified col-
       ormap of the specified window.  The colormap must have the
       same visual type as the window, or a BadMatch error
       results.

       XSetWindowColormap can generate BadColor, BadMatch, and
       BadWindow errors.


DIAGNOSTICS

       BadAccess A client attempted to free a color map entry
                 that it did not already allocate.

       BadAccess A client attempted to store into a read-only
                 color map entry.

       BadColor  A value for a Colormap argument does not name a
                 defined Colormap.

       BadCursor A value for a Cursor argument does not name a
                 defined Cursor.

       BadMatch  Some argument or pair of arguments has the cor-
                 rect type and range but fails to match in some
                 other way required by the request.

       BadMatch  An InputOnly window locks this attribute.

       BadPixmap A value for a Pixmap argument does not name a
                 defined Pixmap.
