Optionmenu Widget

The Optionmenu Widget

Use the Optionmenu method to create an option menu, in which the selected item is the value displayed. For example:

$mainwindow->OptionMenu(-textvariable => \$platform, -options => [ [ "UNIX", "unix" ], [ "Windows", "winnt" ], [ "Macintosh", "mac" ] ]) -> pack;

The -options argument takes a list of menu items. If the description of the menu items that are displayed are different from the values stored, the menu items are themselves written as two-item lists.

The standard configuration options that apply to Optionmenu are: -activebackground, -activeforeground, -background, -bg, -bitmap, -borderwidth, -bw, -cursor, -disabledforeground, -font, -foreground, -fg, -highlightbackground, -highlightcolor, -highlightthickness, -image, -justify, -relief, -state, -takefocus, -underline, -width, and -wraplength.

Other options are:

-command => callback
The command to execute when a selection is made, with its arguments being the values of the -textvariable and -variable options.
-indicatoron => boolean
Determines whether or not to display an indicator.
-menu => $menu
Displays the menu associated with $menu.
-options => list
Lists the menu options, as described above.
-tearoff => boolean
Whether or not to allow the menu to be "torn off." Default is 1.
-text => string
Specifies the text to display as a label for the option menu.
-textvariable => \$variable
Points to the variable containing text to be displayed in the option menu.
-variable => \$variable
Points to a variable containing a stored value, distinct from the value shown in the option menu.
