SYNTAX

       int  XChangeWindowAttributes(Display  *display,  Window  w,   unsigned   long   valuemask,
              XSetWindowAttributes *attributes);

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

       int XSetWindowBackgroundPixmap(Display *display, Window w, Pixmap background_pixmap);

       int XSetWindowBorder(Display *display, Window w, unsigned long border_pixel);

       int XSetWindowBorderPixmap(Display *display, Window w, Pixmap border_pixmap);

       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 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 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
       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 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 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  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 immediately 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 BadWindow errors.

       The XSetWindowBorder function sets the border  of  the  window  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 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 Colormap.

       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.
