DesignerGlyph.GetBounds(ActivityDesigner, Boolean) Method

  • Reference

Definition

Namespace:
System.Workflow.ComponentModel.Design
Assembly:
System.Workflow.ComponentModel.dll

Returns the bounds for the glyph on the specified ActivityDesigner.

public:
 virtual System::Drawing::Rectangle GetBounds(System::Workflow::ComponentModel::Design::ActivityDesigner ^ designer, bool activated);
public virtual System.Drawing.Rectangle GetBounds (System.Workflow.ComponentModel.Design.ActivityDesigner designer, bool activated);
abstract member GetBounds : System.Workflow.ComponentModel.Design.ActivityDesigner * bool -> System.Drawing.Rectangle
override this.GetBounds : System.Workflow.ComponentModel.Design.ActivityDesigner * bool -> System.Drawing.Rectangle
Public Overridable Function GetBounds (designer As ActivityDesigner, activated As Boolean) As Rectangle

Parameters

designer
ActivityDesigner

The ActivityDesigner with which the glyph is associated.

activated
Boolean

true to indicate whether the glyph appears on the activity designer surface; otherwise, false.

Returns

Rectangle

A Rectangle that represents the bounds for the glyph.

Exceptions

ArgumentNullException

designer contains a null reference (Nothing in Visual Basic).

Examples

The following code example demonstrates how you can override the GetBounds method. The code sets the size and location of the custom glyph object.

This code example is part of the Workflow Monitor SDK Sample from the DesignerGlyphProvider.cs file. For more information, see Workflow Monitor.

public override Rectangle GetBounds(ActivityDesigner designer, bool activated)
{
    Rectangle imageBounds = Rectangle.Empty;
    Image image = Resources.Executing;
    if (image != null)
    {
        Size glyphSize = WorkflowTheme.CurrentTheme.AmbientTheme.GlyphSize;
        imageBounds.Location = new Point(designer.Bounds.Right - glyphSize.Width / 2, designer.Bounds.Top - glyphSize.Height / 2);
        imageBounds.Size = glyphSize;
    }
    return imageBounds;
}

Public Overrides Function GetBounds(ByVal designer As System.Workflow.ComponentModel.Design.ActivityDesigner, ByVal activated As Boolean) As System.Drawing.Rectangle
    Dim imageBounds As Rectangle = Rectangle.Empty
    Dim image As Image = AppResources.Executing
    If Not image Is Nothing Then
        Dim glyphSize As Size = WorkflowTheme.CurrentTheme.AmbientTheme.GlyphSize
        imageBounds.Location = New Point(designer.Bounds.Right - glyphSize.Width / 2, designer.Bounds.Top - glyphSize.Height / 2)
        imageBounds.Size = glyphSize
    End If
    Return imageBounds
End Function

Remarks

Unless overridden in a derived class, GetBounds returns the bounds of the activity designer with which the glyph is associated.
