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 descriptions of the menu items displayed are different from those of the values stored, the menu items are themselves written as two-item lists.

The standard configuration options that apply to Optionmenu are: -activeback-ground, -activeforeground, -background, -bg, -bitmap, -borderwidth, -bw, -cursor, -disabledforeground, -font, -foreground, -fg, -highlightbackground, -highlight-color, -highlightthickness, -image, -justify, -relief, -state, -takefocus, -un-derline, -width, and -wraplength.

Other options are:

• -command => callback
• The command to execute when a selection is made. Its arguments are the values of the -textvariable and -variable options.
• -indicatoron => boolean
• Determines whether to display an indicator.
• -menu => $menu
• Displays the menu associated with $menu.
• -options => list
• Lists the menu options, as described above.
• -tearoff => boolean
• Whether to allow the menu to be "torn off." Default is .
• -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.
