Work on the Gui: some of the framework for drag & drop. Also made Window an IWidget.
Implemented getWidget(x,y) to find the widget under this location for IWidgets (but not Gui).
Made Window an IWidget and made it work a little more similarly to widgets.
Implemented callbacks on the Gui for mouse events (enabling drag & drop, etc.).

All init functions are * wrapped in another function before being run in a thread (i.e. run indirectly). Functions fail * either by throwing an exception or by returning a boolean. Functions may take parameters, e.g. * "out cleanupFunc[]". * * This should make it much easier to tell what actually happens during init and to order init such * that dependencies are honoured. * * Currently some external modules depend on InitFunctions, while some are set up from here. Once * all are set up from here, the Init* modules can be rearranged. */ module mde.scheduler.init2; import mde.scheduler.initFunctions; import tango.util.log.Log : Log, Logger; // Modules requiring init code running: import global = mde.global; import mde.gui.Gui; import mde.input.Input; import ft = mde.ft.init; // NOTE: error reporting needs a revision private Logger logger; static this () { logger = Log.getLogger ("mde.scheduler.Init2"); init.addFunc (&initInput, "initInput"); init.addFunc (&guiLoad, "guiLoad"); init.addFunc (&initFreeType, "initFreeType"); } void guiLoad () { // init func try { gui.load ("gui"); } catch (Exception e) { logger.fatal ("guiLoad failed: " ~ e.msg); setInitFailure; } } void initInput () { // init func try { global.input = new Input(); global.input.loadConfig (); // (may also create instance) // Quit on escape.
