.SH SYNOPSIS
|

|

(\fBTk:option-menu \fIw varname value \fR?\fIvalue value ...\fR?)

.SH DESCRIPTION
|
||
|
|
.PP
|
||
|
|
This procedure creates an option menubutton whose name is \fIw\fR,
|
||
|
|
plus an associated menu.
|
||
|
|
Together they allow the user to select one of the values
|
||
|
|
given by the \fIvalue\fR arguments.
|
||
|
|
The current value will be stored in the global variable whose
|
||
|
|
name is given by \fIvarname\fR 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 \fIvalue\fRs 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.
|
||
|
|
.PP
|
||
|
|
The return value from \fBTk:option-menu\fR is the menu
|
||
|
|
associated with \fIw\fR, so that the caller can change its configuration
|
||
|
|
options or manipulate it in other ways.
