lib::Depend<TY> works as drop-in replacement for lib::Singleton<TY> This changeset removes the convoluted special cases like SingletonSub and MockInjector.

/** @file guistart.cpp
|
|
** 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 gui::GuiFacade and
|
|
** controlled by lumiera::AppState, which in turn is activated by Lumiera main().
|
|
**
|
|
** After successfully loading this module, a call to #kickOff is expected to be
|
|
** issued, passing a termination signal (callback) to be executed when the GUI
|
|
** terminates. The \c kickOff() call remains blocked within the main GTK event loop;
|
|
** thus typically this call should be issued within a separate dedicated GUI thread.
|
|
** Especially, the gui::GuiRunner will ensure this to happen.
|
|
**
|
|
** Prior to entering the GTK event loop, all primary "business" interface of the GUI
|
|
** will be opened (currently as of 1/09 this is the interface gui::GuiNotification.)
|
