class Gtk::CellRendererCombo

Overview

Renders a combobox in a cell

Gtk::CellRendererCombo renders text in a cell like Gtk::CellRendererText from which it is derived. But while Gtk::CellRendererText offers a simple entry to edit the text, Gtk::CellRendererCombo offers a Gtk::ComboBox widget to edit the text. The values to display in the combo box are taken from the tree model specified in the Gtk::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 Gtk::CellRendererCombo:text-column property. Further properties of the combo box can be set in a handler for the Gtk::CellRenderer::editing-started signal.

Defined in:

lib/gi-crystal/src/auto/gtk-4.0/cell_renderer_combo.cr

Constructor Detail

def self.new : self #

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