HTk.Widgets.ComboBox

Description

HTk's ComboBox. Only available when using tixwish. However this module needs to go in the uni-htk-widgets package because it depends on it.

Synopsis

Documentation

data GUIValue a => ComboBox a Source #

The ComboBox datatype. A ComboBox is a so called mega widget composed of an entry widget and a list box. Both subwidgets are accessible by themselves.

Instances

GUIValue a => Eq (ComboBox a) Source #
Methods (==) :: ComboBox a -> ComboBox a -> Bool # (/=) :: ComboBox a -> ComboBox a -> Bool #
GUIValue a => Destroyable (ComboBox a) Source #	A combo box widget can be destroyed.
Methods destroy :: ComboBox a -> IO () #
GUIValue a => Synchronized (ComboBox a) Source #	You can synchronize on a combo box widget.
Methods synchronize :: ComboBox a -> IO b -> IO b #
GUIValue a => GUIObject (ComboBox a) Source #	Internal.

GUIValue a => HasEnable (ComboBox a) Source #	A combo box widget is a stateful widget, it can be enabled or disabled.
Methods state :: State -> Config (ComboBox a) Source # getState :: ComboBox a -> IO State Source # disable :: Config (ComboBox a) Source # enable :: Config (ComboBox a) Source # isEnabled :: ComboBox a -> IO Bool Source #
GUIValue a => HasBorder (ComboBox a) Source #	A combo box widget has a configureable border.

GUIValue a => HasSize (ComboBox a) Source #	You can specify the size of a combo box widget-
Methods width :: Distance -> Config (ComboBox a) Source # getWidth :: ComboBox a -> IO Distance Source # height :: Distance -> Config (ComboBox a) Source # getHeight :: ComboBox a -> IO Distance Source # size :: Size -> Config (ComboBox a) Source # getSize :: ComboBox a -> IO Size Source #
GUIValue a => HasColour (ComboBox a) Source #	A combo box widget has a background colour.
Methods legalColourID :: ComboBox a -> ConfigID -> Bool Source # setColour :: ComboBox a -> ConfigID -> Colour -> IO (ComboBox a) Source # getColour :: ComboBox a -> ConfigID -> IO Colour Source #
GUIValue a => HasAnchor (ComboBox a) Source #	A combo box widget has a text anchor.
Methods anchor :: Anchor -> Config (ComboBox a) Source # getAnchor :: ComboBox a -> IO Anchor Source #
GUIValue a => Widget (ComboBox a) Source #	A combo box has standard widget properties (focus, cursor, ...).
Methods cursor :: CursorDesignator ch => ch -> Config (ComboBox a) Source # getCursor :: ComboBox a -> IO Cursor Source # takeFocus :: Bool -> Config (ComboBox a) Source # getTakeFocus :: ComboBox a -> IO Bool Source #
(GUIValue a, GUIValue [a]) => HasValue (ComboBox a) [a] Source #	The value of a combo box is the list of the displayed objects (these are instances of class `GUIValue` and therefore instances of class `Show`).
Methods value :: [a] -> Config (ComboBox a) Source # getValue :: ComboBox a -> IO [a] Source #

newComboBox Source #

Arguments

:: (GUIValue a, Container par)
=> par	the list of configuration options for this combo box.
-> Bool	true if the user should be allowed to type into the entry of the ComboBox.
-> [Config (ComboBox a)]
-> IO (ComboBox a)	A combo box.

Constructs a new combo box and returns a handler.

pick :: GUIValue a => Int -> Config (ComboBox a) Source #

Sets the index item in the listbox to be the current value of the ComboBox.

entrySubwidget :: GUIValue a => ComboBox a -> Entry a Source #

Retrieve the entry subwidget of a combo box.

listBoxSubwidget :: GUIValue a => ComboBox a -> ListBox a Source #

Retrieve the list box subwidget of a combo box.
