Struct gtk4::CellRendererCombo[][src]

pub struct CellRendererCombo(_);
Expand description

Renders a combobox in a cell

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 widget to edit the text. The values to display in the combo box are taken from the tree model specified in the property::CellRendererCombo::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 property::CellRendererCombo::text-column property. Further properties of the combo box can be set in a handler for the signal::CellRenderer::editing-started signal.

Implements

CellRendererTextExt, CellRendererExt, glib::ObjectExt, CellRendererExtManual

Implementations

Creates a new CellRendererCombo. Adjust how text is drawn using object properties. Object properties can be set globally (with g_object_set()). Also, with TreeViewColumn, you can bind a property to a value in a TreeModel. 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 the TreeView.

Returns

the new cell renderer

Creates a new builder-pattern struct instance to construct CellRendererCombo objects.

This method returns an instance of CellRendererComboBuilder which can be used to create CellRendererCombo objects.

pub fn has_entry(&self) -> bool

If true, the cell renderer will include an entry and allow to enter values other than the ones in the popup list.

pub fn set_has_entry(&self, 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.

Holds a tree model containing the possible values for the combo box. Use the text_column property to specify the column holding the values.

Holds a tree model containing the possible values for the combo box. Use the text_column property to specify the column holding the values.

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.

CellRendererCombo automatically adds a text cell renderer for this column to its combo box.

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.

CellRendererCombo automatically adds a text cell renderer for this column to its combo box.

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.

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)
