XSetWMName(3) XLIB FUNCTIONS XSetWMName(3)NAME
XSetWMName, XGetWMName, XStoreName, XFetchName - set or read a window's
WM_NAME property
SYNTAX
void XSetWMName(Display *display, Window w, XTextProperty *text_prop);
Status XGetWMName(Display *display, Window w, XTextProperty
*text_prop_return);
int XStoreName(Display *display, Window w, char *window_name);
Status XFetchName(Display *display, Window w, char **win‐
dow_name_return);
ARGUMENTS
display Specifies the connection to the X server.
text_prop Specifies the XTextProperty structure to be used.
text_prop_return
Returns the XTextProperty structure.
w Specifies the window.
window_name
Specifies the window name, which should be a null-terminated
string.
window_name_return
Returns the window name, which is a null-terminated string.
DESCRIPTION
The XSetWMName convenience function calls XSetTextProperty to set the
WM_NAME property.
The XGetWMName convenience function calls XGetTextProperty to obtain
the WM_NAME property. It returns a nonzero status on success; other‐
wise, it returns a zero status.
The XStoreName function assigns the name passed to window_name to the
specified window. A window manager can display the window name in some
prominent place, such as the title bar, to allow users to identify win‐
dows easily. Some window managers may display a window's name in the
window's icon, although they are encouraged to use the window's icon
name if one is provided by the application. If the string is not in
the Host Portable Character Encoding, the result is implementation-
dependent.
XStoreName can generate BadAlloc and BadWindow errors.
The XFetchName function returns the name of the specified window. If
it succeeds, it returns a nonzero status; otherwise, no name has been
set for the window, and it returns zero. If the WM_NAME property has
not been set for this window, XFetchName sets window_name_return to
NULL. If the data returned by the server is in the Latin Portable
Character Encoding, then the returned string is in the Host Portable
Character Encoding. Otherwise, the result is implementation-dependent.
When finished with it, a client must free the window name string using
XFree.
XFetchName can generate a BadWindow error.
PROPERTIES
WM_NAME The name of the application.
DIAGNOSTICS
BadAlloc The server failed to allocate the requested resource or
server memory.
BadWindow A value for a Window argument does not name a defined Window.
