CellRenderer.addOnEditingStarted

This signal gets emitted when a cell starts to be edited. The intended use of this signal is to do special setup on @editable, e.g. adding a #GtkEntryCompletion or setting up additional columns in a #GtkComboBox.

Note that GTK+ doesn't guarantee that cell renderers will continue to use the same kind of widget for editing in future releases, therefore you should check the type of @editable before doing any specific setup, as in the following example: |[<!-- language="C" --> static void text_editing_started (GtkCellRenderer *cell, GtkCellEditable *editable, const gchar *path, gpointer data) { if (GTK_IS_ENTRY (editable)) { GtkEntry *entry = GTK_ENTRY (editable);

// ... create a GtkEntryCompletion

gtk_entry_set_completion (entry, completion); } } ]|
