ShadowDepth Property

WorkflowView.ShadowDepth Property

Gets or sets the ShadowDepth for the WorkflowView.

Namespace: System.Workflow.ComponentModel.Design
Assembly: System.Workflow.ComponentModel (in system.workflow.componentmodel.dll)

public int ShadowDepth { get; set; }
/** @property */
public int get_ShadowDepth ()

/** @property */
public void set_ShadowDepth (int value)

public function get ShadowDepth () : int

public function set ShadowDepth (value : int)

Not applicable.

Property Value

The shadow depth in pixels.

Use the ShadowDepth to get or adjust the shadow depth of text shown on the workflow design surface.

The following code example demonstrates how you can obtain an instance of the WorkflowView class using the GetView method. The code then sets several WorkflowView properties, including HScrollBar and VScrollBar, ShadowDepth, and calls the FitToScreenSize method.

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);
        }
    }
}

The UnloadWorkflow method that is called in the code above removes a currently loaded workflow in order to prepare for the loading of a new workflow and is implemented as follows:

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;
    }
}
