WorkflowView.ShadowDepth 속성

정의

네임스페이스:

System.Workflow.ComponentModel.Design

어셈블리:

System.Workflow.ComponentModel.dll

ShadowDepth의 WorkflowView를 가져오거나 설정합니다.

public:
 property int ShadowDepth { int get(); void set(int value); };

public int ShadowDepth { get; set; }

member this.ShadowDepth : int with get, set

Public Property ShadowDepth As Integer

속성 값

Int32

픽셀 단위로 나타낸 그림자 수준입니다.

예제

다음 코드 예제에서는 WorkflowView 메서드를 사용하여 GetView 클래스의 인스턴스를 가져오는 방법을 보여 줍니다. 그런 다음 코드에서는 WorkflowView, HScrollBar 및 VScrollBar를 포함한 여러 ShadowDepth 속성을 설정하고 FitToScreenSize 메서드를 호출합니다.

IDesignerHost designerHost = designSurface.GetService(typeof(IDesignerHost)) as IDesignerHost;
if (designerHost != null && designerHost.RootComponent != null)
{
    IRootDesigner rootDesigner = designerHost.GetDesigner(designerHost.RootComponent) as IRootDesigner;
    if (rootDesigner != null)
    {
        UnloadWorkflow();

        this.designSurface = designSurface;
        this.loader = loader;
        this.workflowView = rootDesigner.GetView(ViewTechnology.Default) as WorkflowView;
        this.splitContainer1.Panel1.Controls.Add(this.workflowView);
        this.workflowView.Dock = DockStyle.Fill;
        this.workflowView.TabIndex = 1;
        this.workflowView.TabStop = true;
        this.workflowView.HScrollBar.TabStop = false;
        this.workflowView.VScrollBar.TabStop = false;
        this.workflowView.ShadowDepth = 0;
        this.workflowView.EnableFitToScreen = true;
        this.workflowView.Focus();

        ISelectionService selectionService = GetService(typeof(ISelectionService)) as ISelectionService;
        IComponentChangeService changeService = GetService(typeof(IComponentChangeService)) as IComponentChangeService;

        if (selectionService != null)
        {
            selectionService.SelectionChanged += new EventHandler(OnSelectionChanged);
        }

        if (changeService != null)
        {
            changeService.ComponentAdded += new ComponentEventHandler(changeService_ComponentAdded);
            changeService.ComponentChanged += new ComponentChangedEventHandler(changeService_ComponentChanged);
            changeService.ComponentRemoved += new ComponentEventHandler(changeService_ComponentRemoved);
            changeService.ComponentRename += new ComponentRenameEventHandler(changeService_ComponentRename);
        }
    }
}

Dim designerHost As IDesignerHost = CType(designSurface.GetService(GetType(IDesignerHost)), IDesignerHost)
If designerHost IsNot Nothing And designerHost.RootComponent IsNot Nothing Then

    Dim rootDesigner As IRootDesigner = CType(designerHost.GetDesigner(designerHost.RootComponent), IRootDesigner)
    If rootDesigner IsNot Nothing Then
        UnloadWorkflow()

        Me.designSurface = designSurface
        Me.loader = loader
        Me.workflowView = CType(rootDesigner.GetView(ViewTechnology.Default), WorkflowView)
        Me.splitContainer1.Panel1.Controls.Add(Me.workflowView)
        Me.workflowView.Dock = DockStyle.Fill
        Me.workflowView.TabIndex = 1
        Me.workflowView.TabStop = True
        Me.workflowView.HScrollBar.TabStop = False
        Me.workflowView.VScrollBar.TabStop = False
        Me.workflowView.ShadowDepth = 0
        Me.workflowView.EnableFitToScreen = True
        Me.workflowView.Focus()

        Dim selectionService As ISelectionService = CType(GetService(GetType(ISelectionService)), ISelectionService)
        Dim changeService As IComponentChangeService = CType(GetService(GetType(IComponentChangeService)), IComponentChangeService)

        If selectionService IsNot Nothing Then
            AddHandler selectionService.SelectionChanged, AddressOf OnSelectionChanged
        End If

        If changeService IsNot Nothing Then

            AddHandler changeService.ComponentAdded, AddressOf changeService_ComponentAdded
            AddHandler changeService.ComponentChanged, AddressOf changeService_ComponentChanged
            AddHandler changeService.ComponentRemoved, AddressOf changeService_ComponentRemoved
            AddHandler changeService.ComponentRename, AddressOf changeService_ComponentRename
        End If
    End If
End If

위의 코드에서 호출된 UnloadWorkflow 메서드는 새 워크플로를 준비하기 위해 현재 로드된 워크플로를 제거하며 다음과 같이 구현됩니다.

private void UnloadWorkflow()
{
    IDesignerHost designerHost = GetService(typeof(IDesignerHost)) as IDesignerHost;
    if (designerHost != null && designerHost.Container.Components.Count > 0)
        WorkflowLoader.DestroyObjectGraphFromDesignerHost(designerHost, designerHost.RootComponent as Activity);

    if (this.designSurface != null)
    {
        this.designSurface.Dispose();
        this.designSurface = null;
    }

    if (this.workflowView != null)
    {
        Controls.Remove(this.workflowView);
        this.workflowView.Dispose();
        this.workflowView = null;
    }
}

Private Sub UnloadWorkflow()


    Dim designerHost As IDesignerHost = CType(GetService(GetType(IDesignerHost)), IDesignerHost)
    If designerHost IsNot Nothing And designerHost.Container.Components.Count > 0 Then
        WorkflowLoader.DestroyObjectGraphFromDesignerHost(designerHost, CType(designerHost.RootComponent, Activity))
    End If

    If Me.designSurface IsNot Nothing Then
        Me.designSurface.Dispose()
        Me.designSurface = Nothing
    End If


    If Me.workflowView IsNot Nothing Then
        Controls.Remove(Me.workflowView)
        Me.workflowView.Dispose()
        Me.workflowView = Nothing
    End If

End Sub

설명

워크플로 디자인 화면에 표시된 텍스트의 그림자 수준을 가져오거나 조정하려면 ShadowDepth를 사용합니다.
