Hodnota vlastnosti
Hloubka stínu v pixelech.
Příklady
Následující příklad kódu ukazuje, jak můžete získat instanci WorkflowView třídy pomocí GetView metody. Kód pak nastaví několik WorkflowView vlastností, včetně HScrollBar a VScrollBarShadowDepth, a volá metoduFitToScreenSize.
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

Metoda UnloadWorkflow
, která je volána v kódu výše, odebere aktuálně načtený pracovní postup, aby se připravil na načtení nového pracovního postupu a je implementován následujícím způsobem:
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
Poznámky
ShadowDepth Umožňuje získat nebo upravit hloubku stínu textu zobrazeného na návrhové ploše pracovního postupu.
