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
Token for window. Name of desired option. 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 asso-
ciated 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-
priority 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.
