ARGUMENTS
attributes
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 indicate which attributes
have been set in the structure.
background_pixel
Specifies the pixel that is to be used for the background.
background_pixmap
Specifies the background pixmap, or
border_pixel
Specifies the entry in the colormap.
border_pixmap
Specifies the border pixmap or
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.
DESCRIPTION
Depending on the valuemask, the function uses the window attributes in
the 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 Setting the border or chang‐
ing the background such that the border tile origin changes causes the
border to be repainted. Changing the background of a root window to or
restores the default background pixmap. Changing the border of a root
window to restores the default border pixmap. Changing the win-gravity
does not affect the current position of the window. Changing the back‐
ing-store of an obscured window to or 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 event.
Changing the colormap of a visible window may have no immediate effect
on the screen because the map may not be installed (see Changing the
cursor of a root window to restores the default cursor. Whenever pos‐
sible, 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. However, only one client at a time
can select for and If a client attempts to select any of these event
masks and some other client has already selected one, a error results.
There is only one do-not-propagate-mask for a window, not one per
client.
can generate and errors.
The function sets the background of the window to the specified pixel
value. Changing the background does not cause the window contents to
be changed. uses a pixmap of undefined size filled with the pixel
value you passed. If you try to change the background of an window, a
error results.
can generate and errors.
The 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 is specified, the back‐
ground pixmap of the window's parent is used, or on the root window,
the default background is restored. If you try to change the back‐
ground of an window, a error results. If the background is set to the
window has no defined background.
can generate and errors.
The function sets the border of the window to the pixel value you spec‐
ify. If you attempt to perform this on an window, a error results.
can generate and errors.
The 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 a copy of the
parent window's border pixmap is used. If you attempt to perform this
on an window, a error results.
can generate and errors.
The function sets the specified colormap of the specified window. The
colormap must have the same visual type as the window, or a error
results.
can generate and errors.
DIAGNOSTICS
A client attempted
to free a color map entry that it did not already allocate.
A client attempted
to store into a read-only color map entry.
A value for a Colormap argument does not name a defined Colormap.
A value for a Cursor argument does not name a defined Cursor.
Some argument or pair of arguments has the correct type and range but
fails
to match in some other way required by the request.
An window locks this attribute.
A value for a Pixmap argument does not name a defined Pixmap.
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.
A value for a Window argument does not name a defined Window.
