XmbSetWMProperties

Syntax

void XmbSetWMProperties(display, w, window_name, icon_name, argv, argc,
                      normal_hints, wm_hints, class_hints)
      Display *display;
      Window w;
      char *window_name;
      char *icon_name;
      char *argv[];
      int argc;
      XSizeHints *normal_hints;
      XWMHints *wm_hints;
      XClassHint *class_hints;

Arguments

display Specifies the connection to the X server.
w Specifies the window.
window_name Specifies the window name, which should be a null-terminated string.
icon_name Specifies the icon name, which should be a null-terminated string.
argv Specifies the application's argument list.
argc Specifies the number of arguments.
hints Specifies the size hints for the window in its normal state.
wm_hints Specifies the XWMHints structure to be used.
class_hints Specifies the XClassHint structure to be used.

Description

The XmbSetWMProperties() convenience function provides a simple 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, XmbSetWMProperties() sets the WM_NAME property. If the icon_name argument is non-NULL, XmbSetWMProperties() sets the WM_ICON_NAME property. The window_name and icon_name arguments are null-terminated strings in the encoding of the current locale. 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() calls XSetWMNormalHints(), which sets the WM_NORMAL_HINTS property (see section "Setting and Reading the WM_NORMAL_HINTS Property"). If the wm_hints argument is non-NULL, XmbSetWMProperties() calls XSetWMHints(), which sets the WM_HINTS property (see section "Setting and Reading the WM_HINTS Property").

If the argv argument is non-NULL, XmbSetWMProperties() sets 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 "Setting and Reading the WM_CLIENT_MACHINE Property").

If the class_hints argument is non-NULL, XmbSetWMProperties() sets the WM_CLASS property. If the res_name member in the XClassHint structure is set to the NULL pointer and the RESOURCE_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 substituted for res_name.

It is assumed that the supplied class_hints.res_name and argv, the RESOURCE_NAME environment variable, and the hostname of the machine are in the encoding of the locale announced for the LC_CTYPE category (on POSIX-compliant systems, the LC_CTYPE, else LANG environment variable). 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 prior to storage in the properties.

For clients that need to process the property text in a locale, XmbSetWMProperties() sets the WM_LOCALE_NAME property 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.

XmbSetWMProperties() can generate BadAlloc and BadWindow errors.

Diagnostics

BadAlloc The server failed to allocate the requested source or server memory.
BadWindow A value for a Window argument does not name a defined Window.
