Question

我有简单的WPF应用程序，主窗口和按钮，点击后会创建一个新的模态子项通过我的窗口管理器窗口：

class WindowManager : IWindowManager
    {       
        public void AddNewViewWindow()
        {
            var someWindow = new AddNewView();
            someWindow.ShowInTaskbar = false; 
            someWindow.Owner = Application.Current.MainWindow;
            someWindow.ShowDialog();            
        }
    }

主窗口：

<Window x:Class="LogView.Views.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:prism="http://prismlibrary.com/"
        prism:ViewModelLocator.AutoWireViewModel="True"
        Title="{Binding Title}" Height="350" Width="525">
    <StackPanel>
        <StackPanel Orientation="Horizontal">
            <ContentControl prism:RegionManager.RegionName="ContentRegion" />
            <Button Name="AddNewControl" Content="Add New Control" Command="{Binding AddNewViewCommand}" Margin="10">
                <Button.Background>
                    <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                        <GradientStop Color="Black" Offset="0"/>
                        <GradientStop Color="White" Offset="1"/>
                    </LinearGradientBrush>
                </Button.Background>               
            </Button>
            <CheckBox Name="EditMode" Content="Edit mode" IsChecked="{Binding EditModeEnabled}" Margin="10"/>
        </StackPanel>        
    </StackPanel>
</Window>

ModalChildWindow：

<Window x:Class="LogView.Views.AddNewView"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:LogView.Views"
        xmlns:prism ="http://prismlibrary.com/"
        prism:ViewModelLocator.AutoWireViewModel="True"
        mc:Ignorable="d"
        Title="AddNewView" Height="450" Width="800">
    <StackPanel>

    <TreeView ItemsSource="{Binding DeviceSets}" >
        <TreeView.ItemTemplate>
            <DataTemplate>
                <TreeViewItem Header="{Binding Name}"   ItemsSource="{Binding Registers}">
                    <TreeViewItem.ItemTemplate>
                        <DataTemplate>
                            <TextBox Text="{Binding Name}">
                            </TextBox>
                        </DataTemplate>
                    </TreeViewItem.ItemTemplate>
                </TreeViewItem>
            </DataTemplate>
        </TreeView.ItemTemplate>
    </TreeView>
</StackPanel>
</Window>

我也在使用Prism，我的引导程序：

class Bootstrapper : UnityBootstrapper
    {
    protected override DependencyObject CreateShell()
    {
        return Container.Resolve<MainWindow>();
    }

    protected override void InitializeShell()
    {            
        Application.Current.MainWindow.Show();
    }
    protected override void ConfigureContainer()
    {
        base.ConfigureContainer();                                 
        RegisterTypeIfMissing(typeof(IWindowManager), typeof(WindowManager), true);           
    }

    protected override void ConfigureModuleCatalog()
    {
        var moduleCatalog = (ModuleCatalog)ModuleCatalog;
        moduleCatalog.AddModule(typeof(WebSocketClientModule));            
    }
}

现在，我遇到了这种奇怪的行为：

单击按钮时，会显示模态子窗口。一切都很好，我无法点击父（MainWindow）窗口。然后，如果我最小化这个子模态窗口，然后重新打开它，子窗口将停止模态。我可以单击MainWindow并创建第二个模态窗口（第一个仍然可见）。甚至奇怪，第二个模态窗口是真正的模态，当我最小化它，把它带上我不能点击父窗口。如果我关闭第二个模态窗口，我可以再次创建它。问候

子窗口在最小化后停止模态化
