◆ widget_to_gui_component_map()

nocl::WidgetToGUIComponentMap & nocl::GUIComponent::widget_to_gui_component_map ( void )

staticinherited

There are times when we have a pointer to a Gtk+ widget, and we need to map it back to the corresponding NOCL GUI component.

For example, during event handling, Gtk+ tells us which Gtk+ widget generated the event, but we need the corresponding NOCL object so we can call the event handler with a reference to the correct object.

Note: This is not intended for end-users to access directly!
