GI.Gtk.Objects.CellRendererCombo

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 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 CellRendererCombo:text-column property. Further properties of the combo box can be set in a handler for the CellRenderer::editing-started signal.

The CellRendererCombo cell renderer was added in GTK+ 2.6.

Returns: the new cell renderer

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.

Since: 2.6
