Question

伙计我有MVP设计模式的问题因为我不知道如何以父表格显示子视图。我的观点没有MdiParent属性。我可以在视图界面中手动创建它吗？

在新窗口中打开每个表单的丑陋外观！

我有两位主持人：

MainPresenter（代表mainForm（父）逻辑）
TaskPresenter（表示保存，插入，删除逻辑的逻辑）

两个View界面：

IMainView
ITaskView

两个winforms：

MainForm - mainwindow（parrent mdi form）
TaskForm

检查代码：

MainPresenter

public class MainPresenter
{
    private readonly IMainView view;

    private List<ITaskModel> tasks;

    // Constructor
    public MainPresenter(IMainView view)
    {
        this.view = view;
        this.Init();
        this.tasks = new List<ITaskModel>();
    }

    // Initialize
    private void Init()
    {
        this.view.AddTask += AddTask;
    }

    // Add task
    private void AddTask(object sender, EventArgs e)
    {
        // Show as MDI CHILD 
    }
}

IMainView

  public interface IMainView 
  {
        event EventHandler<EventArgs> AddTask;
  }

TaskPresenter

public class TaskPresenter 
{
    private readonly ITaskView view;
    private List<ITaskModel> tasks;

    private bool isNew = true;
    private int currentIndex = 0;

    // Constructor
    public TaskPresenter(ITaskView view)
    {
        this.view = view;
        this.Initialize();
    }

    // Initialize
    public void Initialize()
    {
        tasks = new List<ITaskModel>();

        view.SaveTask += Save;
        view.NewTask += New;
        view.PrevTask += Previous;
        view.NextTask += Next;
    }

    private void Save(object sender, EventArgs e)
    {
    }
    private void New(object sender, EventArgs e)
    {
    }     
    private void Next(object sender, EventArgs e)
    {
    }
    private void Previous(object sender, EventArgs e)
    {
    }
    private void BlankTask()
    {   
    }
    private void LoadTask(ITaskModel task)
    { 
    }
}

ITaskView

public interface ITaskView
{
    String TaskName { get; set; }
    String TaskPriority { get; set; }
    DateTime? StartDate { get; set; }
    DateTime? DuoDate { get; set; }

    event EventHandler<EventArgs> SaveTask;
    event EventHandler<EventArgs> NewTask;
    event EventHandler<EventArgs> NextTask;
    event EventHandler<EventArgs> PrevTask;
}

这是MainForm

public partial class MainForm : Form, IMainView
{
    MainPresenter Presenter;

    // Construcor
    public MainForm()
    {
        InitializeComponent();
    }

    // Events
    public event EventHandler<EventArgs> AddTask;

    // On load
    private void MainForm_Load(object sender, EventArgs e)
    {
        Presenter = new MainPresenter(this);
    }

    // On click add task btn
    private void addTaskBtn_Click(object sender, EventArgs e)
    {
        if(AddTask != null)
        {
            // When is this event triggered i want to show another child form for adding new task
            AddTask(this, EventArgs.Empty); 
        }
    }
}

那么如何在TaskView中将MainView视为孩子呢？

UIApplication它是Windows Forms Application但输出类型Class Library。添加参考MVPFramework

MainForm

public partial class MainForm : Form , IMainView
{
    [Resolve]
    public IMainControl mainControl;

    public MainForm()
    {
        InitializeComponent();
    }


    public bool ShowAsDialog()
    {
        throw new NotImplementedException();
    }

    private void openChildFormToolStripMenuItem_Click(object sender, EventArgs e)
    {
        mainControl.OnOpenChildForm();
    }
}

儿童表格

public partial class ChildForm : Form , IChildView
    {
        public ChildForm()
        {
            InitializeComponent();
        }

        public bool ShowAsDialog()
        {
            throw new NotImplementedException();
        }


        public object MDIparent
        {
            set
            {
                this.MdiParent = (Form)value;
            }
        }
    }

CoreApplication是类库

IMainControl

 public interface  IMainControl :IControl
  {
      void OnOpenChildForm();
  }

MainControl

public class MainControl  :IMainControl
    {
        [Resolve]
      public IApplicationController applicationController;
      public void OnOpenChildForm()
      {
       IChildControl TransfersOnTheWayControl = applicationController.Resolve<IChildControl>();
       TransfersOnTheWayControl.Run();
      }
    }

IChildControl

 public interface IChildControl :IControl
      {
         void Run();
      }

IMainView

public interface  IMainView :IView
{

}

IChildView

public interface IChildView：IView {

      bool ShowAsDialog();`enter code here`

      object MDIparent { set; }
  }

IMainPresenter

public interface  IMainPresenter :IPresenter
 {

 }

IChildPresenter

public interface  IChildPresenter :IPresenter
 {
   bool Ask();
 }

MainPresenter

public class MainPresenter :BasePresenter<IMainView>, IMainPresenter
 {

 }

ChildPresenter

public class ChildPresenter : BasePresenter<IChildView>, IChildPresenter
    {

       public bool Ask()
       {
            this.Init();
            bool res = View.ShowAsDialog();
            ApplicationController.ClearInstance<IChildView>();
            return res;
       }

        public override void Init()
        {
            View.MDIparent = ApplicationController.GetMainFrom<IMainPresenter>();
            base.Init();
        }
    }

LauncherApplication它是控制台应用程序，但输出类型为Windows Form。

 class Program
        {
            static void Main(string[] args)
            {
                IApplicationController applicationController = new ApplicationController(new ServicesContainerAdapter());

                applicationController


                    //RegisterView
                    .RegisterView<IMainView, MainForm>()
                    .RegisterView<IChildView, ChildForm>()


                    //RegisterPresenter
                    .RegisterPresenter<IMainPresenter, MainPresenter>()
                    .RegisterPresenter<IChildPresenter, ChildPresenter>()


                    //RegisterController
                    .RegisterController<IMainControl, MainControl>()
                    .RegisterController<IChildControl, ChildControl>();



                IMainPresenter mainPresenter = applicationController.Resolve<IMainPresenter>();
                mainPresenter.Init();

                Application.Run((Form)mainPresenter.FormObject);
            }
       }
