|
|
This procedure creates an option menubutton whose name is <I>w</I>,
|
|
plus an associated menu.
|
|
Together they allow the user to select one of the values
|
|
given by the <I>value</I> arguments.
|
|
The current value will be stored in the global variable whose
|
|
name is given by <I>varname</I> and it will also be displayed as the label
|
|
in the option menubutton.
|
|
The user can click on the menubutton to display a menu containing
|
|
all of the <I>value</I>s and thereby select a new value.
|
|
Once a new value is selected, it will be stored in the variable
|
|
and appear in the option menubutton.
|
|
The current value can also be changed by setting the variable.
|
|
<P>
|
|
The return value from <B>Tk:option-menu</B> is the menu
|
|
associated with <I>w</I>, so that the caller can change its configuration
|
|
options or manipulate it in other ways.
