private DesignerActionListCollection actionLists;
Private lists As DesignerActionListCollection
public override DesignerActionListCollection ActionLists
{
    get
    {
        if (null == actionLists)

Remarks

DesignerActionListCollection 类表示智能标记面板中所有项的聚合。The DesignerActionListCollection class represents the aggregation of all the items in a smart tag panel. DesignerActionListCollection 类包含零个或多个 DesignerActionList 对象。The DesignerActionListCollection class contains zero or more DesignerActionList objects. 其中每个列表都包含零个或多个对象,这些对象表示面板中的实际项并且派生自 DesignerActionItem 类。Each of these lists contains zero or more objects that represent the actual items in the panel and are derived from the DesignerActionItem class.

下表显示了两种用于向面板提供组件项(包括自定义控件)的 DesignerActionListCollection 方法。The following table shows the two techniques for supplying a DesignerActionListCollection to populate the panel with items for components, including custom controls.

方法Technique 说明Description
请求模型Pull model 组件类的设计器(派生自 ComponentDesigner 类)通过 ActionLists 属性提供此集合。The designer for the component class, which is derived from the ComponentDesigner class, supplies this collection through the ActionLists property. 设计器基础结构在必须显示面板时读取此属性。The designer infrastructure reads this property when it must display the panel.
推送模型Push model 在对与组件关联的 DesignerActionServiceAdd 方法的调用中,将 DesignerActionListDesignerActionListCollection 作为参数提供。A DesignerActionList or DesignerActionListCollection is supplied as a parameter in a call to the Add method of the DesignerActionService associated with the component.

设计器基础结构通过创建智能标记面板来构造面板,其构造函数采用两个类型的参数 DesignerActionListCollectionThe designer infrastructure constructs a panel by creating a smart tag panel, whose constructor takes two parameters of type DesignerActionListCollection. 包含拉取和推送项的列表集合合并为一个面板。The collections of lists, which contain the pulled and pushed items, are merged into one panel.

由于它派生自 System.Collections.CollectionBase 类,因此 DesignerActionListCollection 使用内部 ArrayList 存储其 DesignerActionList 对象的集合。Because it derives from the System.Collections.CollectionBase class, DesignerActionListCollection uses an internal ArrayList to store its collection of DesignerActionList objects.
