XCirculateSubwindows(3)


NAME

   XRaiseWindow, XLowerWindow, XCirculateSubwindows,
   XCirculateSubwindowsUp, XCirculateSubwindowsDown, XRestackWindows -
   change window stacking order

SYNTAX

   int XRaiseWindow(Display *display, Window w);

   int XLowerWindow(Display *display, Window w);

   int XCirculateSubwindows(Display *display, Window w, int direction);

   int XCirculateSubwindowsUp(Display *display, Window w);

   int XCirculateSubwindowsDown(Display *display, Window w);

   int XRestackWindows(Display *display, Window windows[], int nwindows);

ARGUMENTS

   direction Specifies the direction (up or down) that you want to
             circulate the window.  You can pass RaiseLowest or
             LowerHighest.

   display   Specifies the connection to the X server.

   nwindows  Specifies the number of windows to be restacked.

   w         Specifies the window.

   windows   Specifies an array containing the windows to be restacked.

DESCRIPTION

   The XRaiseWindow function raises the specified window to the top of the
   stack so that no sibling window obscures it.  If the windows are
   regarded as overlapping sheets of paper stacked on a desk, then raising
   a window is analogous to moving the sheet to the top of the stack but
   leaving its x and y location on the desk constant.  Raising a mapped
   window may generate Expose events for the window and any mapped
   subwindows that were formerly obscured.

   If the override-redirect attribute of the window is False and some
   other client has selected SubstructureRedirectMask on the parent, the X
   server generates a ConfigureRequest event, and no processing is
   performed.  Otherwise, the window is raised.

   XRaiseWindow can generate a BadWindow error.

   The XLowerWindow function lowers the specified window to the bottom of
   the stack so that it does not obscure any sibling windows.  If the
   windows are regarded as overlapping sheets of paper stacked on a desk,
   then lowering a window is analogous to moving the sheet to the bottom
   of the stack but leaving its x and y location on the desk constant.
   Lowering a mapped window will generate Expose events on any windows it
   formerly obscured.

   If the override-redirect attribute of the window is False and some
   other client has selected SubstructureRedirectMask on the parent, the X
   server generates a ConfigureRequest event, and no processing is
   performed.  Otherwise, the window is lowered to the bottom of the
   stack.

   XLowerWindow can generate a BadWindow error.

   The XCirculateSubwindows function circulates children of the specified
   window in the specified direction.  If you specify RaiseLowest,
   XCirculateSubwindows raises the lowest mapped child (if any) that is
   occluded by another child to the top of the stack.  If you specify
   LowerHighest, XCirculateSubwindows lowers the highest mapped child (if
   any) that occludes another child to the bottom of the stack.  Exposure
   processing is then performed on formerly obscured windows.  If some
   other client has selected SubstructureRedirectMask on the window, the X
   server generates a CirculateRequest event, and no further processing is
   performed.  If a child is actually restacked, the X server generates a
   CirculateNotify event.

   XCirculateSubwindows can generate BadValue and BadWindow errors.

   The XCirculateSubwindowsUp function raises the lowest mapped child of
   the specified window that is partially or completely occluded by
   another child.  Completely unobscured children are not affected.  This
   is a convenience function equivalent to XCirculateSubwindows with
   RaiseLowest specified.

   XCirculateSubwindowsUp can generate a BadWindow error.

   The XCirculateSubwindowsDown function lowers the highest mapped child
   of the specified window that partially or completely occludes another
   child.  Completely unobscured children are not affected.  This is a
   convenience function equivalent to XCirculateSubwindows with
   LowerHighest specified.

   XCirculateSubwindowsDown can generate a BadWindow error.

   The XRestackWindows function restacks the windows in the order
   specified, from top to bottom.  The stacking order of the first window
   in the windows array is unaffected, but the other windows in the array
   are stacked underneath the first window, in the order of the array.
   The stacking order of the other windows is not affected.  For each
   window in the window array that is not a sibling of the first window, a
   BadMatch error results.

   If the override-redirect attribute of a window is False and some other
   client has selected SubstructureRedirectMask on the parent, the X
   server generates ConfigureRequest events for each window whose
   override-redirect flag is not set, and no further processing is
   performed.  Otherwise, the windows will be restacked in top-to-bottom
   order.

   XRestackWindows can generate BadWindow error.

DIAGNOSTICS

   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.
