ARGUMENTS
display Specifies the connection to the X server.
value_mask
Specifies which values are to be set using
information in the values structure. This mask
is the bitwise inclusive OR of the valid config-
ure window values bits.
values Specifies the XWindowChanges structure.
w Specifies the window to be reconfigured, moved,
or resized..
width Specifies the width of the window border.
width
height Specify the width and height, which are the
interior dimensions of the window.

y Specify the x and y coordinates, which define
the new location of the top-left pixel of the
window's border or the window itself if it has
no border or define the new position of the win-
dow relative to its parent.
DESCRIPTION
The XConfigureWindow function uses the values specified in
the XWindowChanges structure to reconfigure a window's
size, position, border, and stacking order. Values not
specified are taken from the existing geometry of the win-
dow.
If a sibling is specified without a stack_mode or if the
window is not actually a sibling, a BadMatch error
results. Note that the computations for BottomIf, TopIf,
and Opposite are performed with respect to the window's
final geometry (as controlled by the other arguments
passed to XConfigureWindow), not its initial geometry.
Any backing store contents of the window, its inferiors,
and other newly visible windows are either discarded or
changed to reflect the current screen contents (depending
on the implementation).
XConfigureWindow can generate BadMatch, BadValue, and Bad-
Window errors.
The XMoveWindow function moves the specified window to the
specified x and y coordinates, but it does not change the
window's size, raise the window, or change the mapping
state of the window. Moving a mapped window may or may
not lose the window's contents depending on if the window
is obscured by nonchildren and if no backing store exists.
If the contents of the window are lost, the X server gen-
erates Expose events. Moving a mapped window generates
Expose events on any formerly obscured windows.
If the override-redirect flag of the window is False and
some other client has selected SubstructureRedirectMask on
the parent, the X server generates a ConfigureRequest
event, and no further processing is performed. Otherwise,
the window is moved.
XMoveWindow can generate a BadWindow error.
The XResizeWindow function changes the inside dimensions
of the specified window, not including its borders. This
function does not change the window's upper-left coordi-
nate or the origin and does not restack the window.
Changing the size of a mapped window may lose its contents
and generate Expose events. If a mapped window is made
smaller, changing its size generates Expose events on win-
dows that the mapped window formerly obscured.

If the override-redirect flag of the window is False and
some other client has selected SubstructureRedirectMask on
the parent, the X server generates a ConfigureRequest
event, and no further processing is performed. If either
width or height is zero, a BadValue error results.
XResizeWindow can generate BadValue and BadWindow errors.
The XMoveResizeWindow function changes the size and loca-
tion of the specified window without raising it. Moving
and resizing a mapped window may generate an Expose event
on the window. Depending on the new size and location
parameters, moving and resizing a window may generate
Expose events on windows that the window formerly
obscured.
If the override-redirect flag of the window is False and
some other client has selected SubstructureRedirectMask on
the parent, the X server generates a ConfigureRequest
event, and no further processing is performed. Otherwise,
the window size and location are changed.
XMoveResizeWindow can generate BadValue and BadWindow
errors.
The XSetWindowBorderWidth function sets the specified win-
dow's border width to the specified width.
XSetWindowBorderWidth can generate a BadWindow error.
STRUCTURES
The XWindowChanges structure contains:
/* Configure window value mask bits */
#define CWX (1<<0)
#define CWY (1<<1)
#define CWWidth (1<<2)
#define CWHeight (1<<3)
#define CWBorderWidth (1<<4)
#define CWSibling (1<<5)
#define CWStackMode (1<<6)
/* Values */
typedef struct {
int x, y;
int width, height;
int border_width;
Window sibling;
int stack_mode;
} XWindowChanges;
The x and y members are used to set the window's x and y
coordinates, which are relative to the parent's origin and

indicate the position of the upper-left outer corner of
the window. The width and height members are used to set
the inside size of the window, not including the border,
and must be nonzero, or a BadValue error results.
Attempts to configure a root window have no effect.
The border_width member is used to set the width of the
border in pixels. Note that setting just the border width
leaves the outer-left corner of the window in a fixed
position but moves the absolute position of the window's
origin. If you attempt to set the border-width attribute
of an InputOnly window nonzero, a BadMatch error results.
The sibling member is used to set the sibling window for
stacking operations. The stack_mode member is used to set
how the window is to be restacked and can be set to Above,
Below, TopIf, BottomIf, or Opposite.
DIAGNOSTICS
BadMatch An InputOnly window is used as a Drawable.
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.
BadValue Some numeric value falls outside the range of
values accepted by the request. Unless a spe-
cific 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.
