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
.
Class Hierarchy
Types
data OptionMenu Source
class ButtonClass o => OptionMenuClass o Source
castToOptionMenu :: GObjectClass obj => obj -> OptionMenu Source
toOptionMenu :: OptionMenuClass o => o -> OptionMenu Source
Constructors
optionMenuNew :: IO OptionMenu Source
Create a new option menu.
Methods
optionMenuGetMenu :: OptionMenuClass self => self -> IO Menu Source
Returns the Menu
associated with the OptionMenu
.
optionMenuSetMenu :: (OptionMenuClass self, MenuClass menu) => self -> menu -> IO () Source
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 () Source
Removes the menu from the option menu.
:: OptionMenuClass self | |
=> self | |
-> Int |
|
-> IO () |
Selects the menu item specified by index
making it the newly selected
value for the option menu.
:: 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 Source
The menu of options.
Signals
onOMChanged :: OptionMenuClass self => self -> IO () -> IO (ConnectId self) Source
This signal is called if the selected option has changed.
afterOMChanged :: OptionMenuClass self => self -> IO () -> IO (ConnectId self) Source
This signal is called if the selected option has changed.
