ARGUMENTS

25       display   Specifies the connection to the X server.
26
27       value_mask
28                 Specifies which values are to be set using information in the
29                 values structure.  This mask is the bitwise inclusive OR of
30                 the valid configure window values bits.
31
32       values    Specifies the XWindowChanges structure.
33
34       w         Specifies the window to be reconfigured, moved, or resized..
35
36       width     Specifies the width of the window border.
37
38       width
39       height    Specify the width and height, which are the interior dimen‐
40                 sions of the window.
41
42       x
43       y         Specify the x and y coordinates, which define the new loca‐
44                 tion of the top-left pixel of the window's border or the win‐
45                 dow itself if it has no border or define the new position of
46                 the window relative to its parent.

DESCRIPTION

49       The XConfigureWindow function uses the values specified in the XWin‐
50       dowChanges structure to reconfigure a window's size, position, border,
51       and stacking order.  Values not specified are taken from the existing
52       geometry of the window.
53
54       If a sibling is specified without a stack_mode or if the window is not
55       actually a sibling, a BadMatch error results.  Note that the computa‐
56       tions for BottomIf, TopIf, and Opposite are performed with respect to
57       the window's final geometry (as controlled by the other arguments
58       passed to XConfigureWindow), not its initial geometry.  Any backing
59       store contents of the window, its inferiors, and other newly visible
60       windows are either discarded or changed to reflect the current screen
61       contents (depending on the implementation).
62
63       XConfigureWindow can generate BadMatch, BadValue, and BadWindow errors.
64
65       The XMoveWindow function moves the specified window to the specified x
66       and y coordinates, but it does not change the window's size, raise the
67       window, or change the mapping state of the window.  Moving a mapped
68       window may or may not lose the window's contents depending on if the
69       window is obscured by nonchildren and if no backing store exists.  If
70       the contents of the window are lost, the X server generates Expose
71       events.  Moving a mapped window generates Expose events on any formerly
72       obscured windows.
73
74       If the override-redirect flag of the window is False and some other
75       client has selected SubstructureRedirectMask on the parent, the X
76       server generates a ConfigureRequest event, and no further processing is
77       performed.  Otherwise, the window is moved.
78
79       XMoveWindow can generate a BadWindow error.
80
81       The XResizeWindow function changes the inside dimensions of the speci‐
82       fied window, not including its borders.  This function does not change
83       the window's upper-left coordinate or the origin and does not restack
84       the window.  Changing the size of a mapped window may lose its contents
85       and generate Expose events.  If a mapped window is made smaller, chang‐
86       ing its size generates Expose events on windows that the mapped window
87       formerly obscured.
88
89       If the override-redirect flag of the window is False and some other
90       client has selected SubstructureRedirectMask on the parent, the X
91       server generates a ConfigureRequest event, and no further processing is
92       performed.  If either width or height is zero, a BadValue error
93       results.
94
95       XResizeWindow can generate BadValue and BadWindow errors.
96
97       The XMoveResizeWindow function changes the size and location of the
98       specified window without raising it.  Moving and resizing a mapped win‐
99       dow may generate an Expose event on the window.  Depending on the new
100       size and location parameters, moving and resizing a window may generate
101       Expose events on windows that the window formerly obscured.
102
103       If the override-redirect flag of the window is False and some other
104       client has selected SubstructureRedirectMask on the parent, the X
105       server generates a ConfigureRequest event, and no further processing is
106       performed.  Otherwise, the window size and location are changed.
107
108       XMoveResizeWindow can generate BadValue and BadWindow errors.
109
110       The XSetWindowBorderWidth function sets the specified window's border
111       width to the specified width.
112
113       XSetWindowBorderWidth can generate a BadWindow error.
114

STRUCTURES

116       The XWindowChanges structure contains:
117
118       /* Configure window value mask bits */
119
120       #define   CWX                         (1<<0)
121       #define   CWY                         (1<<1)
122       #define   CWWidth                     (1<<2)
123       #define   CWHeight                    (1<<3)
124       #define   CWBorderWidth               (1<<4)
125       #define   CWSibling                   (1<<5)
126       #define   CWStackMode                 (1<<6)
127       /* Values */
128
129       typedef struct {
130               int x, y;
131               int width, height;
132               int border_width;
133               Window sibling;
134               int stack_mode;
135       } XWindowChanges;
136
137       The x and y members are used to set the window's x and y coordinates,
138       which are relative to the parent's origin and indicate the position of
139       the upper-left outer corner of the window.  The width and height mem‐
140       bers are used to set the inside size of the window, not including the
141       border, and must be nonzero, or a BadValue error results.  Attempts to
142       configure a root window have no effect.
143
144       The border_width member is used to set the width of the border in pix‐
145       els.  Note that setting just the border width leaves the outer-left
146       corner of the window in a fixed position but moves the absolute posi‐
147       tion of the window's origin.  If you attempt to set the border-width
148       attribute of an InputOnly window nonzero, a BadMatch error results.
149
150       The sibling member is used to set the sibling window for stacking oper‐
151       ations.  The stack_mode member is used to set how the window is to be
152       restacked and can be set to Above, Below, TopIf, BottomIf, or Opposite.
153

DIAGNOSTICS

155       BadMatch  An InputOnly window is used as a Drawable.
156
157       BadMatch  Some argument or pair of arguments has the correct type and
158                 range but fails to match in some other way required by the
159                 request.
160
161       BadValue  Some numeric value falls outside the range of values accepted
162                 by the request.  Unless a specific range is specified for an
163                 argument, the full range defined by the argument's type is
164                 accepted.  Any argument defined as a set of alternatives can
165                 generate this error.
166
167       BadWindow A value for a Window argument does not name a defined Window.
