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.
Class Hierarchy
Types
class HBoxClass o => ComboClass o Source
Instances
castToCombo :: GObjectClass obj => obj -> Combo Source
toCombo :: ComboClass o => o -> Combo Source
Constructors
Methods
comboSetPopdownStrings :: (ComboClass self, GlibString string) => self -> [string] -> IO () Source
Insert a set of Strings into the
Combo drop down list.
Arguments
| :: ComboClass self | |
| => self | |
| -> Bool |
|
| -> Bool |
|
| -> 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
Attributes
comboEnableArrowKeys :: ComboClass self => Attr self Bool Source
Whether the arrow keys move through the list of items.
Default value: True
comboEnableArrowsAlways :: ComboClass self => Attr self Bool Source
Obsolete property, ignored.
Default value: True
comboCaseSensitive :: ComboClass self => Attr self Bool Source
Whether list item matching is case sensitive.
Default value: False
comboAllowEmpty :: ComboClass self => Attr self Bool Source
Whether an empty value may be entered in this field.
Default value: True
comboValueInList :: ComboClass self => Attr self Bool Source
Whether entered values must already be present in the list.
Default value: False
