Graphics.UI.Gtk.ModelView.CellRendererCombo
Description
Renders a combo box in a cell
- Module available since Gtk+ version 2.6
- data CellRendererCombo
- class CellRendererTextClass o => CellRendererComboClass o
- castToCellRendererCombo :: GObjectClass obj => obj -> CellRendererCombo
- gTypeCellRendererCombo :: GType
- toCellRendererCombo :: CellRendererComboClass o => o -> CellRendererCombo
- cellRendererComboNew :: IO CellRendererCombo
- cellComboHasEntry :: CellRendererComboClass self => Attr self Bool
- cellComboTextModel :: (TreeModelClass (model row), TypedTreeModelClass model, CellRendererComboClass self, GlibString string) => WriteAttr self (model row, ColumnId row string)
Detail
CellRendererCombo renders text in a cell like
CellRendererText from which it is derived. But
while CellRendererText offers a simple entry to
edit the text, CellRendererCombo offers a
ComboBox or
ComboBoxEntry widget to edit the text. The
values to display in the combo box are taken from the tree model specified
in the model property.
The combo cell renderer takes care of adding a text cell renderer to the
combo box and sets it to display the column specified by its
cellTextModel property. Further cell renderers can be added in a handler
for the editingStarted signal.

Types
data CellRendererCombo Source
class CellRendererTextClass o => CellRendererComboClass o Source
castToCellRendererCombo :: GObjectClass obj => obj -> CellRendererCombo Source
toCellRendererCombo :: CellRendererComboClass o => o -> CellRendererCombo Source
Constructors
cellRendererComboNew :: IO CellRendererCombo Source
Creates a new CellRendererCombo. This Renderer allows for displaying
a fixed set of options the user can choose from.
Attributes
cellComboHasEntry :: CellRendererComboClass self => Attr self Bool Source
If True, the cell renderer will allow the user to enter
values other than the ones in the popup list.
Default value: True
cellComboTextModel :: (TreeModelClass (model row), TypedTreeModelClass model, CellRendererComboClass self, GlibString string) => WriteAttr self (model row, ColumnId row string) Source
The tuple containing a model and a column in this model that determine
the possible strings that can be shown in the combo box. Note that this
tree model can be a datum in the tree model that is used to populate the
view in which the CellRendererCombo is part of. In other words, it is
possible that every CellRendererCombo can show a different set of
options on each row.
