ARGUMENTS
Specifies the connection to the X server. Specifies which values are
to be set using information in the values structure. This mask is the
bitwise inclusive OR of the valid configure window values bits. Speci‐
fies the XWindowChanges structure. Specifies the window to be recon‐
figured, moved, or resized.. Specifies the width of the window border.
Specify the width and height, which are the interior dimensions of the
window. 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 window relative to its
parent.
DESCRIPTION
The XConfigureWindow function uses the values specified in the XWin‐
dowChanges 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 computa‐
tions 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 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 win‐
dow may or may not lose the window's contents depending on if the win‐
dow is obscured by nonchildren and if no backing store exists. If the
contents 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 window is moved.
XMoveWindow can generate a BadWindow error.
The XResizeWindow function changes the inside dimensions of the speci‐
fied window, not including its borders. This function 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, chang‐
ing 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 win‐
dow 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 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 bor‐
der, and must be nonzero, or a BadValue error results. Attempts to con‐
figure a root window have no effect.
The border_width member is used to set the width of the border in pix‐
els. Note that setting just the border width leaves the outer-left cor‐
ner 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 oper‐
ations. 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
An InputOnly window is used as a Drawable. Some argument or pair of
arguments has the correct type and range but fails to match in some
other way required by the request. 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. A value for a Window argument does not name a
defined Window.
