不能与Caliburn.Micro一起使用windowManager.ShowWindow()

问题描述 投票:0回答:1

[我目前正在为Revit(BIM软件)开发一个插件,我正在尝试使用WPF和Caliburn.Micro在按下插件的按钮时显示窗口/对话框。

所以像在文档中一样,我有一个引导程序:

public class Bootstrapper : BootstrapperBase
{

    public Bootstrapper()
    {
        Initialize();
    }

    protected override void OnStartup(object sender, StartupEventArgs e)
    {
        DisplayRootViewFor<LocationPopupViewModel>();
    }
}
}

一个简单的测试ViewModel:

namespace ExternalForms.ViewModels
{

public class LocationPopupViewModel : Screen
{
    private int _horizontalLength;
    private int _verticalLength;

    public int HorizontalLength
    {
        get 
        { 
            return _horizontalLength; 
        }
        set 
        { 
            _horizontalLength = value;
            NotifyOfPropertyChange(() => HorizontalLength);
        }
    }

    public int VerticalLength
    {
        get 
        { 
            return _verticalLength; 
        }
        set 
        { 
            _verticalLength = value;
            NotifyOfPropertyChange(() => VerticalLength);
        }
    }
}
}

当然还有我要显示的窗口:

<Window x:Class="ExternalForms.Views.LocationPopupView"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:local="clr-namespace:ExternalForms.Views"
    mc:Ignorable="d" WindowStartupLocation="CenterScreen"
    ResizeMode="CanResizeWithGrip"
    Title="gebied" Height="300" Width="410"
    FontSize="16">
<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="20"/>
        <ColumnDefinition Width="auto"/>
        <ColumnDefinition Width="auto"/>
        <ColumnDefinition Width="auto"/>
        <ColumnDefinition Width="auto"/>
        <ColumnDefinition Width="auto"/>
        <ColumnDefinition Width="auto"/>
        <ColumnDefinition Width="auto"/>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="20"/>
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="20"/>
        <RowDefinition Height="auto"/>
        <RowDefinition Height="auto"/>
        <RowDefinition Height="auto"/>
        <RowDefinition Height="auto"/>
        <RowDefinition Height="auto"/>
        <RowDefinition Height="auto"/>
        <RowDefinition Height="auto"/>
        <RowDefinition Height="auto"/>
        <RowDefinition Height="auto"/>
        <RowDefinition Height="auto"/>
        <RowDefinition Height="auto"/>
        <RowDefinition Height="*"/>
        <RowDefinition Height="20"/>
    </Grid.RowDefinitions>


    <!--Row 1-->
    <TextBlock Text="Stel xxx in" FontWeight="DemiBold" Grid.Column="1" Grid.Row="1" FontSize="18"/>

    <!--Row 2-->
    <StackPanel Grid.Row="2" Grid.Column="1" Grid.ColumnSpan="2" Width="360" Margin="0, 0, 0, 20">
        <TextBlock TextWrapping="Wrap">
            Let op dat het gebied een maximale horizontale en verticale lengte mag hebben van 1 kilometer.
        </TextBlock>
    </StackPanel>


    <!--Row 3-->
    <TextBlock Text="Horizontaal" Grid.Column="1" Grid.Row="3"/>

    <!--Row 4-->
    <TextBox x:Name="HorizontalLength" Grid.Row="4" Grid.Column="1" MinWidth="100"/>


    <!--Row 5-->
    <TextBlock Text="Verticaal" Grid.Column="1" Grid.Row="5"/>

    <!--Row 6-->
    <TextBox x:Name="VerticalLength" Grid.Row="6" Grid.Column="1" MinWidth="100"/>


    <!--Row 7-->
    <StackPanel Orientation="Horizontal" Grid.Row="7" Grid.Column="1" Margin="0, 20, 0, 0" Grid.ColumnSpan="2" HorizontalAlignment="Right">
        <Button x:Name="SubmitDimensions" IsDefault="True" Width="100" Height="30">OK</Button>
        <Button IsCancel="True" IsDefault="True" Width="100" Height="30">Cancel</Button>
    </StackPanel>

</Grid>

试图显示窗口的功能:

        private void SetBoundingBox()
    {
        IWindowManager windowManager = new WindowManager();

        LocationPopupView locationPopup = new LocationPopupView();

        windowManager.ShowWindow(locationPopup, null, null);

    }

但是当我尝试在Revit中打开对话框时,会弹出一个带有错误的窗口:enter image description here

UPDATE:我当前的项目结构如下:enter image description here

大会“ UI”负责Revit中的所有内部UI元素(因此,即使当前只有一个,Revit中的按钮也是如此。

Revit中的当前按钮调用“ Get3DBAG”程序集,后者执行一些任务,最后调用“ Location”程序集,该程序集调用WPF视图的Windowmanager.showwindow()方法,该方法位于“ ExternalForms”程序集中。

您的问题在下一行。

LocationPopupView locationPopup = new LocationPopupView();

您正在尝试初始化View的实例,而不是ViewModel。您应该将其替换为以下内容。

LocationPopupViewModel locationPopup = new LocationPopupViewModel();

[Caliburn Micro将使用naming convention自行解析相应的视图。

更新:基于评论

根据您的评论,您的View / ViewModel看起来好像在不同的程序集中。在这种情况下,您需要确保Caliburn Micro搜索View时包括该程序集。您可以通过覆盖Bootstrapper中的SelectAssemblies方法来做到这一点。

    protected override IEnumerable<Assembly> SelectAssemblies()
    {
        return new[] 
       {
           Assembly.GetExecutingAssembly()
          // Ensure your external assembly is included.
       };
    }
