XAllocIconSize(3) XLIB FUNCTIONS XAllocIconSize(3)

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

SYNTAX
       XIconSize *XAllocIconSize(void);

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

       Status XGetIconSizes(Display *display, Window w, XIconSize
       **sizelistreturn, int countreturn);

ARGUMENTS
       display   Specifies the connection to the X server.

       count     Specifies the number of items in the size list.

       countreturn
                 Returns the number of items in the size list.

       sizelist Specifies the size list.

       sizelistreturn
                 Returns the size list.

       w         Specifies the window.

DESCRIPTION
       The XAllocIconSize function allocates and returns a pointer to a XIcon‐
       Size structure.  Note that all fields in the XIconSize structure are
       initially set to zero.  If insufficient memory is available, XAllocI‐
       conSize 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 sizelistreturn, use XFree.

       XGetIconSizes can generate a BadWindow error.

PROPERTIES
       WMICONSIZES
                 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 minwidth, minheight;
               int maxwidth, maxheight;
               int widthinc, heightinc;
       } XIconSize;

       The widthinc and heightinc 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.
