get_arrow_size

Description:

public virtual int get_arrow_size (Widget widget)

Gets the size of the expander arrow.

The default implementation tries to retrieve the "expander-size" style property from widget, as it is primarily meant to be used along with a Gtk.TreeView. For those with special needs, it is recommended to override this method.

Parameters:

widget

Widget used to query the "expander-size" style property (should be a Gtk.TreeView.)

Returns:

Size of the expander arrow.
