XChangeWindowAttributes(3) XLIB FUNCTIONS XChangeWindowAttributes(3)
XChangeWindowAttributes, XSetWindowBackground, XSetWindowBackgroundPixmap, XSetWindowBor-
der, XSetWindowBorderPixmap, XSetWindowColormap - change window attributes
int XChangeWindowAttributes(Display *display, Window w, unsigned long valuemask, XSetWin-
int XSetWindowBackground(Display *display, Window w, unsigned long background_pixel);
int XSetWindowBackgroundPixmap(Display *display, Window w, Pixmap background_pixmap);
int XSetWindowBorder(Display *display, Window w, unsigned long border_pixel);
int XSetWindowBorderPixmap(Display *display, Window w, Pixmap border_pixmap);
int XSetWindowColormap(Display *display, Window w, Colormap colormap);
Specifies the structure from which the values (as specified by the value mask)
are to be taken. The value mask should have the appropriate bits set to indi-
cate which attributes have been set in the structure.
Specifies the pixel that is to be used for the background.
Specifies the background pixmap, ParentRelative, or None.
Specifies the entry in the colormap.
Specifies the border pixmap or CopyFromParent.
display Specifies the connection to the X server.
valuemask Specifies which window attributes are defined in the attributes argument. This
mask is the bitwise inclusive OR of the valid attribute mask bits. If valuemask
is zero, the attributes are ignored and are not referenced.
w Specifies the window.
colormap Specifies the colormap.
Depending on the valuemask, the XChangeWindowAttributes function uses the window
attributes in the XSetWindowAttributes structure to change the specified window
attributes. Changing the background does not cause the window contents to be changed. To
repaint the window and its background, use XClearWindow. Setting the border or changing
the background such that the border tile origin changes causes the border to be repainted.
Changing the background of a root window to None or ParentRelative restores the default
background pixmap. Changing the border of a root window to CopyFromParent restores the
default border pixmap. Changing the win-gravity does not affect the current position of
the window. Changing the backing-store of an obscured window to WhenMapped or Always, or
changing the backing-planes, backing-pixel, or save-under of a mapped window may have no
immediate effect. Changing the colormap of a window (that is, defining a new map, not
changing the contents of the existing map) generates a ColormapNotify event. Changing the
colormap of a visible window may have no immediate effect on the screen because the map
may not be installed (see XInstallColormap). Changing the cursor of a root window to None
restores the default cursor. Whenever possible, you are encouraged to share colormaps.
Multiple clients can select input on the same window. Their event masks are maintained
separately. When an event is generated, it is reported to all interested clients. How-
ever, only one client at a time can select for SubstructureRedirectMask, ResizeRedirect-
Mask, and ButtonPressMask. If a client attempts to select any of these event masks and
some other client has already selected one, a BadAccess error results. There is only one
do-not-propagate-mask for a window, not one per client.
XChangeWindowAttributes can generate BadAccess, BadColor, BadCursor, BadMatch, BadPixmap,
BadValue, and BadWindow errors.
The XSetWindowBackground function sets the background of the window to the specified pixel
value. Changing the background does not cause the window contents to be changed.
XSetWindowBackground uses a pixmap of undefined size filled with the pixel value you
passed. If you try to change the background of an InputOnly window, a BadMatch error
XSetWindowBackground can generate BadMatch and BadWindow errors.
The XSetWindowBackgroundPixmap function sets the background pixmap of the window to the
specified pixmap. The background pixmap can immediately be freed if no further explicit
references to it are to be made. If ParentRelative is specified, the background pixmap of
the window's parent is used, or on the root window, the default background is restored.
If you try to change the background of an InputOnly window, a BadMatch error results. If
the background is set to None, the window has no defined background.
XSetWindowBackgroundPixmap can generate BadMatch, BadPixmap, and BadWindow errors.
The XSetWindowBorder function sets the border of the window to the pixel value you spec-
ify. If you attempt to perform this on an InputOnly window, a BadMatch error results.
XSetWindowBorder can generate BadMatch and BadWindow errors.
The XSetWindowBorderPixmap function sets the border pixmap of the window to the pixmap you
specify. The border pixmap can be freed immediately if no further explicit references to
it are to be made. If you specify CopyFromParent, a copy of the parent window's border
pixmap is used. If you attempt to perform this on an InputOnly window, a BadMatch error
XSetWindowBorderPixmap can generate BadMatch, BadPixmap, and BadWindow errors.
The XSetWindowColormap function sets the specified colormap of the specified window. The
colormap must have the same visual type as the window, or a BadMatch error results.
XSetWindowColormap can generate BadColor, BadMatch, and BadWindow errors.
BadAccess A client attempted to free a color map entry that it did not already allocate.
BadAccess A client attempted to store into a read-only color map entry.
BadColor A value for a Colormap argument does not name a defined Colormap.
BadCursor A value for a Cursor argument does not name a defined Cursor.
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.
BadMatch An InputOnly window locks this attribute.
BadPixmap A value for a Pixmap argument does not name a defined Pixmap.
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.
