public virtual signal void row_selected (ListBoxRow? row)
The row_selected signal is emitted when a new row is selected, or (with a null
row) when the selection is cleared.
When the box is using MULTIPLE, this signal will not give
you the full picture of selection changes, and you should use the
selected_rows_changed signal instead.
