- int XRaiseWindow(Display
*display, Window w);
- int XLowerWindow(Display *display, Window w);
- int
XCirculateSubwindows(Display *display, Window w, int
- direction);
- int XCirculateSubwindowsUp(Display

- int XRestackWindows(Display *display, Window windows[], int

- 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.
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 child of the specified 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.
- 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.
