11 int XConfigureWindow(Display *display, Window w, unsigned value_mask,
12 XWindowChanges *changes);
13 int XMoveWindow(Display *display, Window w, int x, y);
15 int XResizeWindow(Display *display, Window w, unsigned width, unsigned
17 height);
18 int XMoveResizeWindow(Display *display, Window w, int x, int y,
20 unsigned width, unsigned height);
21 int XSetWindowBorderWidth(Display *display, Window w, unsigned width);
23
25 display Specifies the connection to the X server.
26 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 values Specifies the XWindowChanges structure.
33 w Specifies the window to be reconfigured, moved, or resized..
35 width Specifies the width of the window border.
37 width
39 height Specify the width and height, which are the interior dimen‐
40 sions of the window.
41 x
45 y Specify the x and y coordinates, which define the new loca‐
46 tion of the top-left pixel of the window's border or the win‐
47 dow itself if it has no border or define the new position of
48 the window relative to its parent.

51 The XConfigureWindow function uses the values specified in the XWin‐
52 dowChanges structure to reconfigure a window's size, position, border,
53 and stacking order. Values not specified are taken from the existing
54 geometry of the window.
55 If a sibling is specified without a stack_mode or if the window is not
57 actually a sibling, a BadMatch error results. Note that the computa‐
58 tions for BottomIf, TopIf, and Opposite are performed with respect to
59 the window's final geometry (as controlled by the other arguments
60 passed to XConfigureWindow), not its initial geometry. Any backing
61 store contents of the window, its inferiors, and other newly visible
62 windows are either discarded or changed to reflect the current screen
63 contents (depending on the implementation).
64 XConfigureWindow can generate BadMatch, BadValue, and BadWindow errors.
66 The XMoveWindow function moves the specified window to the specified x
68 and y coordinates, but it does not change the window's size, raise the
69 window, or change the mapping state of the window. Moving a mapped
70 window may or may not lose the window's contents depending on if the
71 window is obscured by nonchildren and if no backing store exists. If
72 the contents of the window are lost, the X server generates Expose
73 events. Moving a mapped window generates Expose events on any formerly
74 obscured windows.
75 If the override-redirect flag of the window is False and some other
77 client has selected SubstructureRedirectMask on the parent, the X
78 server generates a ConfigureRequest event, and no further processing is
79 performed. Otherwise, the window is moved.
80 XMoveWindow can generate a BadWindow error.
82 The XResizeWindow function changes the inside dimensions of the speci‐
84 fied window, not including its borders. This function does not change
85 the window's upper-left coordinate or the origin and does not restack
86 the window. Changing the size of a mapped window may lose its contents
87 and generate Expose events. If a mapped window is made smaller, chang‐
88 ing its size generates Expose events on windows that the mapped window
89 formerly obscured.
90 If the override-redirect flag of the window is False and some other
92 client has selected SubstructureRedirectMask on the parent, the X
93 server generates a ConfigureRequest event, and no further processing is
94 performed. If either width or height is zero, a BadValue error
95 results.
96 XResizeWindow can generate BadValue and BadWindow errors.
98 The XMoveResizeWindow function changes the size and location of the
100 specified window without raising it. Moving and resizing a mapped win‐
101 dow may generate an Expose event on the window. Depending on the new
102 size and location parameters, moving and resizing a window may generate
103 Expose events on windows that the window formerly obscured.
104 If the override-redirect flag of the window is False and some other
106 client has selected SubstructureRedirectMask on the parent, the X
107 server generates a ConfigureRequest event, and no further processing is
108 performed. Otherwise, the window size and location are changed.
109 XMoveResizeWindow can generate BadValue and BadWindow errors.
111 The XSetWindowBorderWidth function sets the specified window's border
113 width to the specified width.
114 XSetWindowBorderWidth can generate a BadWindow error.
116
118 The XWindowChanges structure contains:
119 /* Configure window value mask bits */
121 #define CWX (1<<0)
123 #define CWY (1<<1)
124 #define CWWidth (1<<2)
125 #define CWHeight (1<<3)
126 #define CWBorderWidth (1<<4)
127 #define CWSibling (1<<5)
128 #define CWStackMode (1<<6)
129 /* Values */
130 typedef struct {
132 int x, y;
133 int width, height;
134 int border_width;
135 Window sibling;
136 int stack_mode;
137 } XWindowChanges;
138 The x and y members are used to set the window's x and y coordinates,
140 which are relative to the parent's origin and indicate the position of
141 the upper-left outer corner of the window. The width and height mem‐
142 bers are used to set the inside size of the window, not including the
143 border, and must be nonzero, or a BadValue error results. Attempts to
144 configure a root window have no effect.
145 The border_width member is used to set the width of the border in pix‐
147 els. Note that setting just the border width leaves the outer-left
148 corner of the window in a fixed position but moves the absolute posi‐
149 tion of the window's origin. If you attempt to set the border-width
150 attribute of an InputOnly window nonzero, a BadMatch error results.
151 The sibling member is used to set the sibling window for stacking oper‐
153 ations. The stack_mode member is used to set how the window is to be
154 restacked and can be set to Above, Below, TopIf, BottomIf, or Opposite.
155
157 BadMatch An InputOnly window is used as a Drawable.
158 BadMatch Some argument or pair of arguments has the correct type and
160 range but fails to match in some other way required by the
161 request.
162 BadValue Some numeric value falls outside the range of values accepted
164 by the request. Unless a specific range is specified for an
165 argument, the full range defined by the argument's type is
166 accepted. Any argument defined as a set of alternatives can
167 generate this error.
168 BadWindow A value for a Window argument does not name a defined Window.
