This event-driven // separation allows for cleanly implementing logic like: // "If the Inbox is selected, then only display these two menu items, // but if a project is displayed, then display these additional menu items." // See the Handle methods inside of MainFormController.cs for an example. // Event-centric approaches are one of the nicest ways to build // plug-in systems because plug-ins have services and contracts which are linked // to behaviors (and in our case, these are events). // Example: All CaptureThoughtController knows is that it gets handed a View // that it controls (CaptureThoughtForm) and then it has two other injections points, // a Bus and a MainQueue. // See CaptureThoughtController for more comments on how this design works. // The big idea here is that in the future, a controller can be passed an // INTERFACE (say, ICaptureThoughtForm) INSTEAD OF a concrete Windows Forms // implementation (CaptureThoughtForm) like it currently uses. // So we may have a WPF form in the future that implements ICaptureThoughtForm // and we could use that View implementation with the SAME CONTROLLER we already have. // Very similar to how you could use the MVVM pattern with MvvmCross to // reuse common code from the ViewModel down, but implement // platform-specific Views on top of that common/shared code. #endregion #region Wiring up our Views to Controllers... // A "Controller" or "Service" in this client-side ecosystem would usually // define at least two parameters: // MainQueue // and // "Bus" // MainQueue is the place where it would send events that happen inside of it. // Bus is what it subscribes to so that it will be called when specifc events happen. // "Wire" is a static method defined on these controllers that our setup // can call to let them know which form they control, // the bus they can use as a source to subscribe to UI events to react to, // and the target queue that they can use tell the rest of the world about events they generate. #endregion MainFormController.Wire(form, mainQueue, uiBus); AddStuffToInboxController.Wire(new AddStuffToInboxForm(form), uiBus, mainQueue); AddActionToProjectController.Wire(new AddActionToProjectForm(form),uiBus, mainQueue ); DefineProjectController.Wire(new DefineProjectForm(form), uiBus, mainQueue); InboxController.Wire(form.MainRegion, mainQueue, uiBus, provider); NavigationController.Wire(navigation, mainQueue, uiBus, provider); ProjectController.Wire(form.MainRegion, mainQueue, uiBus, provider); NavigateBackController.Wire(uiBus, mainQueue, form); mainQueue.Enqueue(new AppInit()); mainQueue.Start(); Application.Run(form); }
