Tk_GetOption(3Tk)					     Tk_GetOption(3Tk)


NAME    [Toc]    [Back]

     Tk_GetOption - retrieve an	option from the	option database

SYNOPSIS    [Toc]    [Back]

     #include <tk.h>

     Tk_Uid
     Tk_GetOption(tkwin, name, class)

ARGUMENTS    [Toc]    [Back]

     Tk_Window	 tkwin	  (in)	    Token for window.

     char	 *name	  (in)	    Name of desired option.

     char	 *class	  (in)	    Class of desired option.  Null means there
				    is no class	for this option;  do lookup
				    based on name only.

DESCRIPTION    [Toc]    [Back]

     This procedure is invoked to retrieve an option from the database
     associated	with tkwin's main window.  If there is an option for tkwin
     that matches the given name or class, then	it is returned in the form of
     a Tk_Uid.	If multiple options match name and class, then the highestpriority
 one is returned.	If no option matches, then NULL	is returned.

     Tk_GetOption caches options related to tkwin so that successive calls for
     the same tkwin will execute much more quickly than	successive calls for
     different windows.
