ARGUMENTS
argc Specifies the number of arguments.
argv Specifies the application's argument list.
class_hints
Specifies the XClassHint structure to be used.
display Specifies the connection to the X server.
icon_name Specifies the icon name, which should be a null-terminated
string.
normal_hints
Specifies the size hints for the window in its normal state.
w Specifies the window.
window_name
Specifies the window name, which should be a null-terminated
string.
wm_hints Specifies the XWMHints structure to be used.
DESCRIPTION
The XSetWMProperties convenience function provides a single programming
interface for setting those essential window properties that are used
for communicating with other clients (particularly window and session
managers).
If the window_name argument is non-NULL, XSetWMProperties calls XSetWM-
Name, which in turn, sets the WM_NAME property (see section 14.1.4).
If the icon_name argument is non-NULL, XSetWMProperties calls XSetWMI-
conName, which sets the WM_ICON_NAME property (see section 14.1.5). If
the argv argument is non-NULL, XSetWMProperties calls XSetCommand,
which sets the WM_COMMAND property (see section 14.2.1). Note that an
argc of zero is allowed to indicate a zero-length command. Note also
that the hostname of this machine is stored using XSetWMClientMachine
(see section 14.2.2).
If the normal_hints argument is non-NULL, XSetWMProperties calls
XSetWMNormalHints, which sets the WM_NORMAL_HINTS property (see section
14.1.7). If the wm_hints argument is non-NULL, XSetWMProperties calls
XSetWMHints, which sets the WM_HINTS property (see section 14.1.6).
If the class_hints argument is non-NULL, XSetWMProperties calls XSet-
ClassHint, which sets the WM_CLASS property (see section 14.1.8). If
the res_name member in the XClassHint structure is set to the NULL
pointer and the RESOURCE_NAME environment variable is set, then the
value of the environment variable is substituted for res_name. If the
res_name member is NULL, the environment variable is not set, and argv
and argv[0] are set, then the value of argv[0], stripped of any direc-
tory prefixes, is substituted for res_name.
The XmbSetWMProperties and Xutf8SetWMProperties convenience functions
provide a simple programming interface for setting those essential win-
dow properties that are used for communicating with other clients (par-
ticularly window and session managers).
If the window_name argument is non-NULL, they set the WM_NAME property.
If the icon_name argument is non-NULL, they set the WM_ICON_NAME prop-
erty. The window_name and icon_name arguments are null-terminated
strings, for XmbSetWMProperties in the encoding of the current locale,
for Xutf8SetWMProperties in UTF-8 encoding. If the arguments can be
fully converted to the STRING encoding, the properties are created with
type “STRING”; otherwise, the arguments are converted to Compound Text,
and the properties are created with type “COMPOUND_TEXT”.
If the normal_hints argument is non-NULL, XmbSetWMProperties and
Xutf8SetWMProperties call XSetWMNormalHints, which sets the WM_NOR-
MAL_HINTS property (see section 14.1.7). If the wm_hints argument is
non-NULL, XmbSetWMProperties and Xutf8SetWMProperties call XSetWMHints,
which sets the WM_HINTS property (see section 14.1.6).
If the argv argument is non-NULL, XmbSetWMProperties and Xutf8SetWM-
Properties set the WM_COMMAND property from argv and argc. An argc of
zero indicates a zero-length command.
The hostname of the machine is stored using XSetWMClientMachine (see
section 14.2.2).
If the class_hints argument is non-NULL, XmbSetWMProperties and
Xutf8SetWMProperties set the WM_CLASS property. If the res_name member
in the XClassHint structure is set to the NULL pointer and the RE-
SOURCE_NAME environment variable is set, the value of the environment
variable is substituted for res_name. If the res_name member is NULL,
the environment variable is not set, and argv and argv[0] are set, then
the value of argv[0], stripped of any directory prefixes, is substi-
tuted for res_name.
It is assumed that the supplied class_hints.res_name and argv, the RE-
SOURCE_NAME environment variable, and the hostname of the machine are
in the encoding of the current locale. The corresponding WM_CLASS,
WM_COMMAND, and WM_CLIENT_MACHINE properties are typed according to the
local host locale announcer. No encoding conversion is performed for
these strings prior to storage in the properties.
For clients that need to process the property text in a locale, Xmb-
SetWMProperties and Xutf8SetWMProperties set the WM_LOCALE_NAME prop-
erty to be the name of the current locale. The name is assumed to be
in the Host Portable Character Encoding and is converted to STRING for
storage in the property.
XSetWMProperties, XmbSetWMProperties and Xutf8SetWMProperties can gen-
erate BadAlloc and BadWindow errors.
The function Xutf8SetWMProperties is an extension introduced by The
XFree86 Project, Inc., in their 4.0.2 release. Its presence is indi-
cated by the macro X_HAVE_UTF8_STRING.
PROPERTIES
WM_CLASS Set by application programs to allow window and session man-
agers to obtain the application's resources from the resource
database.
WM_CLIENT_MACHINE
The string name of the machine on which the client applica-
tion is running.
WM_COMMAND
The command and arguments, null-separated, used to invoke the
application.
WM_HINTS Additional hints set by the client for use by the window man-
ager. The C type of this property is XWMHints.
WM_ICON_NAME
The name to be used in an icon.
WM_NAME The name of the application.
WM_NORMAL_HINTS
Size hints for a window in its normal state. The C type of
this property is XSizeHints.
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.
