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 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 interior
dimensions of the window.
x 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 window 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 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
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 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
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
specified 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, 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 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 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 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 generate this error.
BadWindow A value for a Window argument does not name a defined
Window.
