定義

命名空間:

System.Windows.Forms

組件:

System.Windows.Forms.dll

提供 ButtonClick 事件的資料。

public ref class ToolBarButtonClickEventArgs : EventArgs

public class ToolBarButtonClickEventArgs : EventArgs

type ToolBarButtonClickEventArgs = class
    inherit EventArgs

Public Class ToolBarButtonClickEventArgs
Inherits EventArgs

繼承

ToolBarButtonClickEventArgs

範例

下列範例會具現化 a 和三個 ToolBarToolBarButton 控制項。 工具列按鈕會指派給按鈕集合、將集合指派給工具列，並將工具列新增至表單。 在 ButtonClick 工具列的事件上，會 Button 評估 的 ToolBarButtonClickEventArgs 屬性，並開啟適當的對話方塊。 此程式碼假設 Form 已具現化 、、 OpenFileDialog 、 SaveFileDialog 和 PrintDialog 。

      toolBar1 = gcnew ToolBar;
