Tk_GetOption(3) Tk Library Procedures Tk_GetOption(3) ________________________________________________________________________________ NAME Tk_GetOption - retrieve an option from the option database SYNOPSIS #include <tk.h> Tk_Uid Tk_GetOption(tkwin, name, class) ARGUMENTS Tk_Window tkwin (in) Token for window. const char *name (in) Name of desired option. const char *class (in) Class of desired option. Null means there is no class for this option; do lookup based on name only. ________________________________________________________________________________ DESCRIPTION This procedure is invoked to retrieve an option from the database associ- ated 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 highest-prior- ity 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.
