WindowVisibilityEventsClass.WindowHiding 事件

  • 發行項

這個 API 支援 .NET Framework 基礎結構，但您不可以直接在程式碼中使用它。

當視窗隱藏時呼叫。

命名空間：  EnvDTE80
組件：  EnvDTE80 (在 EnvDTE80.dll 中)

語法

'宣告
Public Overridable Event WindowHiding As _dispWindowVisibilityEvents_WindowHidingEventHandler

public virtual event _dispWindowVisibilityEvents_WindowHidingEventHandler WindowHiding

public:
virtual  event _dispWindowVisibilityEvents_WindowHidingEventHandler^ WindowHiding {
    void add (_dispWindowVisibilityEvents_WindowHidingEventHandler^ value);
    void remove (_dispWindowVisibilityEvents_WindowHidingEventHandler^ value);
}

abstract WindowHiding : IEvent<_dispWindowVisibilityEvents_WindowHidingEventHandler,
    EventArgs>
override WindowHiding : IEvent<_dispWindowVisibilityEvents_WindowHidingEventHandler,
    EventArgs>

JScript 不支援事件。

實作

_dispWindowVisibilityEvents_Event.WindowHiding

備註

按一下框架右上角的 'x'，即可隱藏視窗。

範例

這個範例中，會使用增益集來連接 WindowVisibilityEvents。以下列範例程式碼取代 Connect.vb 或 Connect.cs 檔案中的程式碼。在 Visual Studio IDE 中執行增益集，並開啟 [命令視窗] 以及關閉 [輸出視窗]，讓事件擷取方法運作。如需如何執行 Automation 範例的詳細資訊，請參閱 HOW TO：編譯和執行 Automation 物件模型程式碼範例。
