ActivityDesigner.Bounds 属性

定义

命名空间:

System.Workflow.ComponentModel.Design

程序集:

System.Workflow.ComponentModel.dll

获取一个 Rectangle，其中包含环绕设计器的矩形的值（以逻辑坐标表示）。

public:
 property System::Drawing::Rectangle Bounds { System::Drawing::Rectangle get(); };

public System.Drawing.Rectangle Bounds { get; }

member this.Bounds : System.Drawing.Rectangle

Public ReadOnly Property Bounds As Rectangle

属性值

Rectangle

包含设计器的 Rectangle。

示例

下面的代码示例演示如何使用 Bounds 属性确定显示在 ActivityDesigner 上的标志符号的新边框。

此代码示例摘自工作流监视器 SDK 示例中的 DesignerGlyphProvider.cs 文件。 有关详细信息，请参阅 工作流监视器。

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

注解

可以使用边界方法所返回的矩形确定由设计器包含的区域以及选定区域。
