Overview

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.

Constructor Details

#initialize ⇒ Gtk::CellRenderer

Creates a new GtkCellRendererCombo.
Adjust how text is drawn using object properties.
Object properties can be set globally (with g_object_set()).
Also, with GtkTreeViewColumn, you can bind a property to a value
in a GtkTreeModel. 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 GtkTreeView.
