ARGUMENTS

29       attributes
30                 Specifies the structure from which the values  (as  specified
31                 by  the  value  mask) are to be taken.  The value mask should
32                 have the appropriate bits set to  indicate  which  attributes
33                 have been set in the structure.
34
35       background_pixel
36                 Specifies the pixel that is to be used for the background.
37
38       background_pixmap
39                 Specifies the background pixmap, ParentRelative, or None.
40
41       border_pixel
42                 Specifies the entry in the colormap.
43
44       border_pixmap
45                 Specifies the border pixmap or CopyFromParent.
46
47       display   Specifies the connection to the X server.
48
49       valuemask Specifies  which  window  attributes  are  defined in the at‐
50                 tributes argument.  This mask is the bitwise inclusive OR  of
51                 the valid attribute mask bits.  If valuemask is zero, the at‐
52                 tributes are ignored and are not referenced.
53
54       w         Specifies the window.
55
56       colormap  Specifies the colormap.
57

DESCRIPTION

59       Depending on the valuemask, the XChangeWindowAttributes  function  uses
60       the  window  attributes in the XSetWindowAttributes structure to change
61       the specified window attributes.   Changing  the  background  does  not
62       cause the window contents to be changed.  To repaint the window and its
63       background, use XClearWindow.  Setting the border or changing the back‐
64       ground such that the border tile origin changes causes the border to be
65       repainted.  Changing the background of a root window to None or  Paren‐
66       tRelative  restores the default background pixmap.  Changing the border
67       of a root window to CopyFromParent restores the default border  pixmap.
68       Changing  the  win-gravity  does not affect the current position of the
69       window.  Changing the backing-store of an obscured window to WhenMapped
70       or Always, or changing the backing-planes, backing-pixel, or save-under
71       of a mapped window may have no immediate effect.  Changing the colormap
72       of  a window (that is, defining a new map, not changing the contents of
73       the existing map) generates a ColormapNotify event.  Changing the  col‐
74       ormap  of  a  visible window may have no immediate effect on the screen
75       because the map may not be installed (see XInstallColormap).   Changing
76       the cursor of a root window to None restores the default cursor.  When‐
77       ever possible, you are encouraged to share colormaps.
78
79       Multiple clients can select input on  the  same  window.   Their  event
80       masks are maintained separately.  When an event is generated, it is re‐
81       ported to all interested clients.  However, only one client at  a  time
82       can  select  for SubstructureRedirectMask, ResizeRedirectMask, and But‐
83       tonPressMask.  If a client attempts to select any of these event  masks
84       and  some  other client has already selected one, a BadAccess error re‐
85       sults.  There is only one do-not-propagate-mask for a window,  not  one
86       per client.
87
88       XChangeWindowAttributes  can  generate  BadAccess, BadColor, BadCursor,
89       BadMatch, BadPixmap, BadValue, and BadWindow errors.
90
91       The XSetWindowBackground function sets the background of the window  to
92       the  specified pixel value.  Changing the background does not cause the
93       window contents to be changed.  XSetWindowBackground uses a  pixmap  of
94       undefined  size  filled with the pixel value you passed.  If you try to
95       change the background of an InputOnly window, a BadMatch error results.
96
97       XSetWindowBackground can generate BadMatch and BadWindow errors.
98
99       The XSetWindowBackgroundPixmap function sets the background  pixmap  of
100       the  window to the specified pixmap.  The background pixmap can immedi‐
101       ately be freed if no further explicit references to it are to be  made.
102       If  ParentRelative  is specified, the background pixmap of the window's
103       parent is used, or on the root window, the default  background  is  re‐
104       stored.   If you try to change the background of an InputOnly window, a
105       BadMatch error results.  If the background is set to None,  the  window
106       has no defined background.
107
108       XSetWindowBackgroundPixmap  can  generate BadMatch, BadPixmap, and Bad‐
109       Window errors.
110
111       The XSetWindowBorder function sets the border  of  the  window  to  the
112       pixel  value  you  specify.  If you attempt to perform this on an Inpu‐
113       tOnly window, a BadMatch error results.
114
115       XSetWindowBorder can generate BadMatch and BadWindow errors.
116
117       The XSetWindowBorderPixmap function sets the border pixmap of the  win‐
118       dow  to the pixmap you specify.  The border pixmap can be freed immedi‐
119       ately if no further explicit references to it are to be made.   If  you
120       specify  CopyFromParent, a copy of the parent window's border pixmap is
121       used.  If you attempt to perform this on an InputOnly  window,  a  Bad‐
122       Match error results.
123
124       XSetWindowBorderPixmap  can generate BadMatch, BadPixmap, and BadWindow
125       errors.
126
127       The XSetWindowColormap function sets  the  specified  colormap  of  the
128       specified  window.   The colormap must have the same visual type as the
129       window, or a BadMatch error results.
130
131       XSetWindowColormap can generate BadColor, BadMatch, and  BadWindow  er‐
132       rors.

DIAGNOSTICS

135       BadAccess A  client attempted to free a color map entry that it did not
136                 already allocate.
137
138       BadAccess A client attempted to store into a read-only color map entry.
139
140       BadColor  A value for a Colormap argument does not name a defined  Col‐
141                 ormap.
142
143       BadCursor A value for a Cursor argument does not name a defined Cursor.
144
145       BadMatch  Some  argument  or pair of arguments has the correct type and
146                 range but fails to match in some other way  required  by  the
147                 request.
148
149       BadMatch  An InputOnly window locks this attribute.
150
151       BadPixmap A value for a Pixmap argument does not name a defined Pixmap.
152
153       BadValue  Some numeric value falls outside the range of values accepted
154                 by the request.  Unless a specific range is specified for  an
155                 argument,  the  full  range defined by the argument's type is
156                 accepted.  Any argument defined as a set of alternatives  can
157                 generate this error.
158
159       BadWindow A value for a Window argument does not name a defined Window.
