在两个WPF窗口之间发送事件 [英] Sending event between 2 WPF windows

问题描述

我有两个WPF窗口。一个是主窗口，另一个是一些配置窗口。
我希望配置窗口发送和事件到主窗口。
任何想法我如何实现？

这是我如何创建和打开配置窗口：

  private void MenuItem_Click（object sender，RoutedEventArgs e）
 {
 ConfigPage Confwin = new ConfigPage（）; 
 Confwin.Owner = this; 
 Confwin.Show（）; 
} 
  

解决方案

您可以定义任何事件

主窗口

  public partial class MainWindow：Window 
 {
 public MainWindow（）
 {
 InitializeComponent（）; 
 
 this.Loaded + = new RoutedEventHandler（MainWindow_Loaded）; 
} 
 
 void MainWindow_Loaded（object sender，RoutedEventArgs e）
 {
 Child childWindow = new Child（）; 
 childWindow.MyEvent + = new EventHandler（childWindow_MyEvent）; 
 
 childWindow.ShowDialog（）; 
} 
 
 void childWindow_MyEvent（object sender，EventArgs e）
 {
 // handle事件
 MessageBox.Show（Handle）; 
} 
} 
  

子窗口 p>

  public partial class Child：Window 
 {
 // define event 
 public event EventHandler MyEvent; 
 
 protected void OnMyEvent（）
 {
 if（this.MyEvent！= null）
 this.MyEvent（this，EventArgs.Empty）; 
} 
 
 public Child（）
 {
 InitializeComponent（）; 
 
 this.Loaded + = new RoutedEventHandler（Child_Loaded）; 
} 
 
 void Child_Loaded（object sender，RoutedEventArgs e）
 {
 //调用事件
 this.OnMyEvent（）; 
} 
} 
  

I have two WPF windows. One is the main window and the other is some configuration window. I would like the configuration window to send and event to the main window. Any idea how I an accomplish it?

This is how I create and open the configuration window :

 private void MenuItem_Click(object sender, RoutedEventArgs e)
    {
        ConfigPage Confwin= new ConfigPage();
        Confwin.Owner = this;
        Confwin.Show();
    }

解决方案

You can define any event in your child window class and subscribe to it before showing the window.

Main Window

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();

        this.Loaded += new RoutedEventHandler(MainWindow_Loaded);
    }

    void MainWindow_Loaded(object sender, RoutedEventArgs e)
    {
        Child childWindow = new Child();
        childWindow.MyEvent += new EventHandler(childWindow_MyEvent);

        childWindow.ShowDialog();
    }

    void childWindow_MyEvent(object sender, EventArgs e)
    {
        // handle event
        MessageBox.Show("Handle");
    }
}

Child window

public partial class Child : Window
{
    // define event
    public event EventHandler MyEvent;

    protected void OnMyEvent()
    {
        if (this.MyEvent != null)
            this.MyEvent(this, EventArgs.Empty);
    }

    public Child()
    {
        InitializeComponent();

        this.Loaded += new RoutedEventHandler(Child_Loaded);
    }

    void Child_Loaded(object sender, RoutedEventArgs e)
    {
        // call event
        this.OnMyEvent();
    }
}
