範例

下列程式代碼範例示範如何建立 物件的集合 DesignerActionItem

如需實作智慧標記的完整範例,請參閱 如何:將智慧標記附加至 Windows Forms 元件

備註

DesignerActionTextItem如同基類,DesignerActionHeaderItem代表智慧標記面板中的個別靜態文字專案。 不過, DesignerActionHeaderItem 專案會使用粗體文字來顯示。 一般而言,標題專案是用來在面板中建立一組項目的標題。 按兩下標頭專案不會採取任何動作。

個別面板專案會與一起建立面板,方法是呼叫 GetSortedActionItems 類別的 DesignerActionList 方法。
