Description

A text entry field with a dropdown list

  • Warning: this module is deprecated and should not be used in newly-written code.

Synopsis

Detail

The Combo widget consists of a single-line text entry field and a drop-down list. The drop-down list is displayed when the user clicks on a small arrow button to the right of the entry field.

List elements can contain arbitrary widgets, but if an element is not a plain label, then you must use the comboSetItemString function. This sets the string which will be placed in the text entry field when the item is selected.

By default, the user can step through the items in the list using the arrow (cursor) keys, though this behaviour can be turned off with comboSetUseArrows.

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

Methods

comboSetPopdownStrings :: ComboClass self => self -> [String] -> IO ()Source

Insert a set of Strings into the Combo drop down list.

comboSetValueInListSource

Arguments

:: ComboClass self 
=> self 
-> Bool

val - True if the value entered must match one of the values in the list.

-> Bool

okIfEmpty - True if an empty value is considered valid.

-> IO () 

Specifies whether the value entered in the text entry field must match one of the values in the list. If this is set then the user will not be able to perform any other action until a valid value has been entered.

If an empty field is acceptable, the okIfEmpty parameter should be True.

comboSetUseArrows :: ComboClass self => self -> Bool -> IO ()Source

Specifies if the arrow (cursor) keys can be used to step through the items in the list. This is on by default.

comboSetUseArrowsAlways :: ComboClass self => self -> Bool -> IO ()Source

Obsolete function, does nothing.

comboSetCaseSensitive :: ComboClass self => self -> Bool -> IO ()Source

Specifies whether the text entered into the Entry field and the text in the list items is case sensitive.

This may be useful, for example, when you have called comboSetValueInList to limit the values entered, but you are not worried about differences in case.

comboDisableActivate :: ComboClass self => self -> IO ()Source

Stops the Combo widget from showing the popup list when the Entry emits the "activate" signal, i.e. when the Return key is pressed. This may be useful if, for example, you want the Return key to close a dialog instead.

comboEnableArrowsAlways :: ComboClass self => Attr self BoolSource

comboAllowEmpty :: ComboClass self => Attr self BoolSource
