public System.Workflow.ComponentModel.Design.ActivityDesignerGlyphCollection GetGlyphs (System.Workflow.ComponentModel.Design.ActivityDesigner activityDesigner);
abstract member GetGlyphs : System.Workflow.ComponentModel.Design.ActivityDesigner -> System.Workflow.ComponentModel.Design.ActivityDesignerGlyphCollection
Public Function GetGlyphs (activityDesigner As ActivityDesigner) As ActivityDesignerGlyphCollection

Parametry

Příklady

Následující příklad kódu ukazuje, jak můžete implementovat metodu GetGlyphs pro kreslení vlastní objekty piktogramů na ploše návrháře aktivity.

Tento příklad kódu je součástí ukázky sady SDK pro monitorování pracovních postupů ze souboru DesignerGlyphProvider.cs. Další informace najdete v tématu Monitorování pracovního postupu.
