Renders a combobox in a cell
GtkCellRendererCombo
renders text in a cell like GtkCellRendererText
from
which it is derived. But while GtkCellRendererText
offers a simple entry to
edit the text, GtkCellRendererCombo
offers a GtkComboBox
widget to edit the text. The values to display in the combo box are taken from
the tree model specified in the GtkCellRendererCombo
: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
GtkCellRendererCombo
:text-column property. Further properties of the combo box
can be set in a handler for the GtkCellRenderer::editing-started
signal.
Constructors
- class CellRendererCombo
- classmethod new() CellRenderer
Creates a new
GtkCellRendererCombo
. Adjust how text is drawn using object properties. Object properties can be set globally (withset()
). Also, withGtkTreeViewColumn
, you can bind a property to a value in aGtkTreeModel
. For example, you can bind the “text” property on the cell renderer to a string value in the model, thus rendering a different string in each row of theGtkTreeView
.Deprecated since version 4.10: Please do not use it in newly written code
Properties
- class CellRendererCombo
- props.has_entry: bool
If
True
, the cell renderer will include an entry and allow to enter values other than the ones in the popup list.
- props.model: TreeModel
Holds a tree model containing the possible values for the combo box. Use the text_column property to specify the column holding the values.
- props.text_column: int
Specifies the model column which holds the possible values for the combo box.
Note that this refers to the model specified in the model property, not the model backing the tree view to which this cell renderer is attached.
GtkCellRendererCombo
automatically adds a text cell renderer for this column to its combo box.
Signals
- class CellRendererCombo.signals
- changed(path_string: str, new_iter: TreeIter) None
This signal is emitted each time after the user selected an item in the combo box, either by using the mouse or the arrow keys. Contrary to GtkComboBox, GtkCellRendererCombo::changed is not emitted for changes made to a selected item in the entry. The argument
new_iter
corresponds to the newly selected item in the combo box and it is relative to the GtkTreeModel set via the model property on GtkCellRendererCombo.Note that as soon as you change the model displayed in the tree view, the tree view will immediately cease the editing operating. This means that you most probably want to refrain from changing the model until the combo cell renderer emits the edited or editing_canceled signal.
- Parameters:
path_string – a string of the path identifying the edited cell (relative to the tree view model)
new_iter – the new iter selected in the combo box (relative to the combo box model)
