NAME
XConfigureWindow, XMoveWindow, XResizeWindow, XMo-
veResizeWindow, XSetWindowBorderWidth, XWindowChanges - con-
figure windows and window changes structure
SYNTAX
int XConfigureWindow(Display *display, Window w, unsigned
value_mask);
int XMoveWindow(Display *display, Window w, int x, y);
int XResizeWindow(Display *display, Window w, unsigned
width, unsigned height);
int XMoveResizeWindow(Display *display, Window w, int x, int
y, unsigned width, unsigned height);
int XSetWindowBorderWidth(Display *display, Window w,
unsigned width);
ARGUMENTS
display Specifies the connection to the X server.
value_mask
Specifies which values are to be set using infor-
mation in the values structure. This mask is the
bitwise inclusive OR of the valid configure 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 inte-
rior dimensions of the window. of the window's
border or the window itself if it has no border or
define the new position of the window relative to
its parent
x
y Specify the x and y coordinates, which define the
new location of the top-left pixel.
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 window.

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 XConfi-
gureWindow), not its initial geometry. Any backing store
contents of the window, its inferiors, and other newly visi-
ble windows are either discarded or changed to reflect the
current screen contents (depending on the implementation).
XConfigureWindow can generate BadMatch, BadValue, and
BadWindow 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 con-
tents of the window are lost, the X server generates 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 win-
dow is moved.
XMoveWindow can generate a BadWindow error.
The XResizeWindow function changes the inside dimensions of
the specified window, not including its borders. This func-
tion does not change the window's upper-left coordinate 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 windows 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 location
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 win-
dow size and location are changed.
XMoveResizeWindow can generate BadValue and BadWindow
errors.
The XSetWindowBorderWidth function sets the specified
window'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 posi-
tion but moves the absolute position of the window's origin.
If you attempt to set the border-width attribute of an Inpu-
tOnly 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 correct
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 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 gen-
erate this error.
BadWindow A value for a Window argument does not name a
defined Window.
