示例

下面的代码示例演示如何启用和禁用 Adorner。 有关完整代码列表,请参阅 如何:在设计模式下扩展控件的外观和行为

// The AnchorGlyph objects should mimic the resize glyphs;
// they should only be visible when the control is the 
// primary selection. The adorner is enabled when the 
// control is the primary selection and disabled when 
// it is not.

void selectionService_SelectionChanged(object sender, EventArgs e)
{
    if (object.ReferenceEquals(
        this.selectionService.PrimarySelection,
        this.relatedControl))
    {
        this.ComputeBounds();
        this.anchorAdorner.Enabled = true;
    }
    else
    {
        this.anchorAdorner.Enabled = false;
    }
}
' The AnchorGlyph objects should mimic the resize glyphs;
' they should only be visible when the control is the 
' primary selection. The adorner is enabled when the 
' control is the primary selection and disabled when 
' it is not.
Private Sub selectionService_SelectionChanged( _
ByVal sender As Object, _
ByVal e As EventArgs)

    If Object.ReferenceEquals( _
    Me.selectionService.PrimarySelection, _
    Me.relatedControl) Then
        Me.ComputeBounds()
        Me.anchorAdorner.Enabled = True
    Else
        Me.anchorAdorner.Enabled = False
    End If

End Sub
