              valuemask, XSetWindowAttributes *attributes);

       int XSetWindowBackground(Display *display, Window w, unsigned long
              background_pixel);

       int XSetWindowColormap(Display *display, Window w, Colormap colormap);

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 appropriate 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.

       border_pixel
                 Specifies the entry in the colormap.

       border_pixmap
                 Specifies the border pixmap or CopyFromParent.

       display   Specifies the connection to the X server.

       valuemask Specifies which window attributes are defined in the
                 attributes argument.  This mask is the bitwise inclusive OR
                 of the valid attribute mask bits.  If valuemask is zero, the
                 attributes are ignored and are not referenced.

       w         Specifies the window.

       colormap  Specifies the colormap.

DESCRIPTION

       Depending on the valuemask, the XChangeWindowAttributes function uses
       the window attributes in the XSetWindowAttributes 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 back-
       ground such that the border tile origin changes causes the border to be
       repainted.  Changing the background of a root window to None or Paren-
       tRelative restores the default background pixmap.  Changing the border
       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 col-
       ormap 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.  When-
       ever possible, 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 But-
       tonPressMask.  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 BadMatch error results.

       XSetWindowBackground can generate BadMatch and BadWindow errors.

       The XSetWindowBackgroundPixmap function sets the background pixmap of
       the window to the specified pixmap.  The background pixmap can immedi-
       ately be freed if no further explicit references to it are to be made.
       If ParentRelative is specified, the background pixmap of the window's
       parent is used, or on the root window, the default background is
       restored.  If you try to change the background of an InputOnly window,
       a BadMatch error results.  If the background is set to None, the window
       has no defined background.

       XSetWindowBackgroundPixmap can generate BadMatch, BadPixmap, and Bad-
       Window errors.

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

       XSetWindowBorder can generate BadMatch and BadWindow errors.

       The XSetWindowBorderPixmap function sets the border pixmap of the win-
       dow to the pixmap you specify.  The border pixmap can be freed immedi-
       ately 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 Bad-
       Match error results.

       XSetWindowBorderPixmap can generate BadMatch, BadPixmap, and BadWindow
       errors.

       The XSetWindowColormap function sets the specified colormap 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 Col-
                 ormap.

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

       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.

       BadMatch  An InputOnly window locks this attribute.

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

       BadValue  Some numeric value falls outside the range of values accepted
                 by the request.  Unless a specific range is specified for an
                 argument, the full range defined by the argument's type is
                 accepted.  Any argument defined as a set of alternatives can
                 generate this error.

       BadWindow A value for a Window argument does not name a defined Window.
