同步第二個窗口大小以匹配主窗口大小

Question

我已經嘗試在MainWindow屬性的ResizeMode中導出資源，認爲數據可能與我的Window2 ResizeMode屬性綁定，但它與抓取和拖動位置/值不匹配，它只是匹配屬性值，在這種情況下是我分配給MainWindow的'CanResizeWithGrip'。所以我最終得到了兩個窗口的控制權，並且Window2與MainWindow的調整大小不匹配。我想自動縮小/放大我的Window2，當我點擊並拖動MainWindow上的大小調整。我無法真正掌握LocationChanged或SizeChanged句柄，以及在這種情況下應該如何使用它們。 我的MainWindow有一個視頻文件飼料與VLC插件，我的Window2有一個透明的背景，覆蓋切換按鈕和退出按鈕。如果有人能提供幫助，任何建議/明確的例子都會有幫助。

主窗口：

namespace VLC_Test 
{ 
/// <summary> 
/// Interaction logic for MainWindow.xaml 
/// </summary> 
    public partial class MainWindow : Window 
    { 
    AxAXVLC.AxVLCPlugin vlcPlayer = new AxAXVLC.AxVLCPlugin(); 

    public MainWindow() 
    { 
     InitializeComponent(); 
     WFH1.Child = vlcPlayer;   

    } 

    private void Window_Loaded(object sender, RoutedEventArgs e) 
    { 
     Window2 win2 = new Window2(); 
     win2.Show(); 

     string file1 = @"C:\Users\Username\Desktop\drop.avi"; 

     vlcPlayer.addTarget("file:///" + file1, null, AXVLC.VLCPlaylistMode.VLCPlayListReplaceAndGo, 0); 
     vlcPlayer.play(); 
    }  
    } 
} 

XAML：

<Window x:Class="VLC_Test.MainWindow" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<Window.Background>

</Window.Background> 


    <Grid Width="Auto" Height="Auto">

    </Grid> 
</Window> 

窗口2：

namespace VLC_Test 
{ 
/// <summary> 
/// Interaction logic for Window2.xaml 
/// </summary> 
    public partial class Window2 : Window 
    { 

    public Window2() 
    { 
     InitializeComponent(); 
    } 



    private void Window_Loaded(object sender, RoutedEventArgs e) 
    { 

    } 

    private void button2_Click(object sender, RoutedEventArgs e) 
    { 

     this.Close(); 
     App.Current.Shutdown(); 
    } 

    } 
} 

XAML：

    </Grid>

我會簡單地使用SizeChanged事件。將您的MainWindow XAML更改爲包含對事件處理程序的調用。 （同樣，如果您要在主窗口移動到兩個窗口保持在一起，使用LocationChanged事件，也顯示。）：

<Window x:Class="VLC_Test.MainWindow" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Title="MainWindow" SizeToContent="WidthAndHeight" 
    WindowStartupLocation="Manual" 
    Top="0" Left="7" AllowsTransparency="False" WindowStyle="None" Loaded="Window_Loaded" Topmost="True" ShowInTaskbar="False" BorderThickness="0" ResizeMode="CanResizeWithGrip" 
    SizeChanged="Window_Resize" LocationChanged="Window_Moved"> 

    <Window.Background> 
     <SolidColorBrush Opacity="0" Color="White"/> 
    </Window.Background> 


    <Grid Width="Auto" Height="Auto"> 
     <WindowsFormsHost Height="495" Width="550" HorizontalAlignment="Left" Name="WFH1" VerticalAlignment="Top" Margin="-11,-24,0,0" ChildChanged="WFH1_ChildChanged" />     
    </Grid> 
</Window> 

然後在主窗口你的CS文件，執行該事件。請注意，我在窗口上保存了一個變量來存儲Window2對象，以便在加載後可以返回它。

namespace VLC_Test 
{ 
/// <summary> 
/// Interaction logic for MainWindow.xaml 
/// </summary> 
    public partial class MainWindow : Window 
    { 
    AxAXVLC.AxVLCPlugin vlcPlayer = new AxAXVLC.AxVLCPlugin(); 
    Window2 win2; 

    public MainWindow() 
    { 
     InitializeComponent(); 
     WFH1.Child = vlcPlayer;   

    } 

    private void Window_Loaded(object sender, RoutedEventArgs e) 
    { 
     CreateWindow2Overlay(); 

     string file1 = @"C:\Users\Username\Desktop\drop.avi"; 

     vlcPlayer.addTarget("file:///" + file1, null,  AXVLC.VLCPlaylistMode.VLCPlayListReplaceAndGo, 0); 
     vlcPlayer.play(); 
    } 

    private void CreateWindow2Overlay() 
    { 
     win2 = new Window2(); 
     win2.Left = Left; 
     win2.Top = Top; 
     win2.Width = Width; 
     win2.Height = Height; 
     win2.Owner = this; 
     win2.Show(); 
    } 

    private void Window_Resize(object sender, SizeChangedEventArgs e) 
    { 
     if (win2 != null) 
     { 
      win2.Height = e.NewSize.Height; 
      win2.Left = Left; 
      win2.Width = e.NewSize.Width; 
      win2.Top = Top; 
     } 
    } 

    private void Window_Moved(object sender, EventArgs e) 
    { 
     if (win2 != null) 
     { 
      win2.Left = Left; 
      win2.Top = Top; 
     } 
    } 
    } 
} 

對MainWindow代碼所做的所有更改。我沒有更改Window2的cs或xaml。

該解決方案在Visual Studio 2010中進行了測試。請注意，我添加了設置第二個窗口的CreateWindow2Overlay方法。它專門將Window2的所有者設置爲此（MainWindow），以便將Window2放在MainWindow的前面。

要明確的是，這個問題解決了的變化是： 1.將窗口2上的主窗口 2.更改窗口2的大小頂部對象時，主窗口大小

如果是我很想念你的請求的任何部分，請不要猶豫，指出。

我希望能幫到你。
