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
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.

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 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 XConfigureWindow can generate BadMatch, BadValue, and BadWindow errors.
64 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 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 XMoveWindow can generate a BadWindow error.
80 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 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 XResizeWindow can generate BadValue and BadWindow errors.
96 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 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 XMoveResizeWindow can generate BadValue and BadWindow errors.
109 The XSetWindowBorderWidth function sets the specified window's border
111 width to the specified width.
112 XSetWindowBorderWidth can generate a BadWindow error.
114
116 The XWindowChanges structure contains:
117 /* Configure window value mask bits */
119 #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 typedef struct {
130 int x, y;
131 int width, height;
132 int border_width;
133 Window sibling;
134 int stack_mode;
135 } XWindowChanges;
136 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 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 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
155 BadMatch An InputOnly window is used as a Drawable.
156 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 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 BadWindow A value for a Window argument does not name a defined Window.
