# Detail

A `OptionMenu` is a widget that allows the user to choose from a list of valid choices. The `OptionMenu` displays the selected choice. When activated the `OptionMenu` displays a popup `Menu` which allows the user to make a new choice.

Using a `OptionMenu` is simple; build a `Menu`, by calling `menuNew`, then appending menu items to it with `menuShellAppend`. Set that menu on the option menu with `optionMenuSetMenu`. Set the selected menu item with `optionMenuSetHistory`; connect to the "changed" signal on the option menu; in the "changed" signal, check the new selected menu item with `optionMenuGetHistory`.

As of Gtk+ 2.4, `OptionMenu` has been deprecated in favor of `ComboBox`.

castToOptionMenu :: GObjectClass obj => obj -> OptionMenu

gTypeOptionMenu :: GType

toOptionMenu :: OptionMenuClass o => o -> OptionMenu

# Constructors

optionMenuNew :: IO OptionMenu

Create a new option menu.

# Methods

optionMenuGetMenu :: OptionMenuClass self => self -> IO Menu

Returns the `Menu` associated with the `OptionMenu`.

optionMenuSetMenu :: (OptionMenuClass self, MenuClass menu) => self -> menu -> IO ()

Provides the `Menu` that is popped up to allow the user to choose a new value. You should provide a simple menu avoiding the use of tearoff menu items, submenus, and accelerators.

optionMenuRemoveMenu :: OptionMenuClass self => self -> IO ()

Removes the menu from the option menu.

optionMenuSetHistory

Arguments

:: OptionMenuClass self |
=> self |
-> Int | `index` - the index of the menu item to select. Index values are from 0 to n-1.
-> IO () |

Selects the menu item specified by `index` making it the newly selected value for the option menu.

optionMenuGetHistory

Arguments

:: OptionMenuClass self |
=> self |
-> IO Int | returns index of the selected menu item, or -1 if there are no menu items

Retrieves the index of the currently selected menu item. The menu items are numbered from top to bottom, starting with 0.

# Attributes

optionMenuMenu :: (OptionMenuClass self, MenuClass menu) => ReadWriteAttr self Menu menu

The menu of options.

# Signals

onOMChanged :: OptionMenuClass self => self -> IO () -> IO (ConnectId self)

This signal is called if the selected option has changed.

afterOMChanged :: OptionMenuClass self => self -> IO () -> IO (ConnectId self)

This signal is called if the selected option has changed.
