XGetIconSizes() 														   XGetIconSizes()

Name
  XGetIconSizes - get preferred icon sizes.

Synopsis
  Status XGetIconSizes(display, w, size_list_return, count_return)
	Display *display;
	Window w;
	XIconSize **size_list_return;
	int *count_return;

Arguments
  display  Specifies a connection to an X server; returned from XOpenDisplay().

  w	   Specifies the window ID (usually of the root window).

  size_list_return
	   Returns a pointer to the size list.

  count_return
	   Returns the number of items in the size list.

Returns
  Zero on failure, non-zero on success.

Description
  XGetIconSizes()  reads  the XA_WM_ICON_SIZE property that should be set by the window manager to specify its desired icon sizes.  XGetIcon-
  Sizes() returns a Status of zero if a window manager has not set icon sizes, and a non-zero Status  otherwise.   This  function  should  be
  called  by  all programs to find out what icon sizes are preferred by the window manager.  The application should then use XSetWMHints() to
  supply the window manager with an icon pixmap or window in one of the supported sizes.  To free the data allocated in size_list_return, use
  XFree().

  For more information, see Volume One, Chapter 12, Interclient Communication.

Structures
     typedef struct {
	 int min_width, min_height;
	 int max_width, max_height;
	 int width_inc, height_inc;
     } XIconSize;
     /* width_inc and height_inc provide the preferred increment of sizes in the
      * range from min_width to max_width and min_height to max_height. */

Errors
  BadWindow

NAME

       XAllocIconSize, XSetIconSizes, XGetIconSizes, XIconSize - allocate icon size structure and set or read a window's WM_ICON_SIZES property

SYNTAX

       XIconSize *XAllocIconSize(void);

       int XSetIconSizes(Display *display, Window w, XIconSize *size_list, int count);

       Status XGetIconSizes(Display *display, Window w, XIconSize **size_list_return, int count_return);

ARGUMENTS

       display	 Specifies the connection to the X server.

       count	 Specifies the number of items in the size list.

       count_return
		 Returns the number of items in the size list.

       size_list Specifies the size list.

       size_list_return
		 Returns the size list.

       w	 Specifies the window.

DESCRIPTION

       The XAllocIconSize function allocates and returns a pointer to a XIconSize structure.  Note that all fields in the XIconSize structure are
       initially set to zero.  If insufficient memory is available, XAllocIconSize returns NULL.  To free the memory allocated to this structure,
       use XFree.

       The XSetIconSizes function is used only by window managers to set the supported icon sizes.

       XSetIconSizes can generate BadAlloc and BadWindow errors.

       The XGetIconSizes function returns zero if a window manager has not set icon sizes; otherwise, it return nonzero.  XGetIconSizes should be
       called by an application that wants to find out what icon sizes would be most appreciated by the window manager under which the application
       is running.  The application should then use XSetWMHints to supply the window manager with an icon pixmap or window in one of the supported
       sizes.  To free the data allocated in size_list_return, use XFree.

       XGetIconSizes can generate a BadWindow error.

PROPERTIES

       WM_ICON_SIZES
		 The window manager may set this property on the root window to specify the icon sizes it supports.  The C type of this property
		 is XIconSize.

STRUCTURES

       The XIconSize structure contains:

       typedef struct {
	    int min_width, min_height;
	    int max_width, max_height;
	    int width_inc, height_inc;
       } XIconSize;

       The width_inc and height_inc members define an arithmetic progression of sizes (minimum to maximum) that represent the supported icon
       sizes.

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.
