Description

Start up the Lumiera GTK GUI when loading it as dynamic module.

This plugin is linked together with the Lumiera GUI code; when loaded as Lumiera plugin, it allows to kick off the GTK main event loop and thus to bring up the GUI. The loading and shutdown process is carried out by stage::GuiFacade and controlled by lumiera::AppState, which in turn is activated by Lumiera main().

After successfully loading this module, a call to GuiFacade::launchUI is expected to happen, passing a termination signal (callback) to be executed when the GUI terminates. The implementation of GuiFacade in the GuiRunner in fact issues this call from the ctor body, while the interface is opened via an InstanceHandle member. The launchUI() call starts a new thread, which then becomes the UI event thread and remains blocked within the main GTK event loop. Before entering this loop, the CoreService of the GUI and especially the UI-Bus is started see GtkLumiera::run(). This entails also to open the primary "business" interface(s) of the GUI (currently as of 1/16 this is the interface stage::GuiNotification.)
