Evento WindowVisibilityEventsClass.WindowHiding
Questa API supporta l'infrastruttura .NET Framework e non deve essere utilizzata direttamente dal codice.
Viene chiamato quando una finestra è nascosta.
Spazio dei nomi: EnvDTE80
Assembly: EnvDTE80 (in EnvDTE80.dll)
Sintassi
'Dichiarazione
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 non supporta gli eventi.
Implementa
_dispWindowVisibilityEvents_Event.WindowHiding
Note
Si nasconde una finestra quando si fa clic sulla 'x' nell'angolo superiore destro della cornice.
Esempi
In questo esempio viene utilizzato un componente aggiuntivo per la connessione di WindowVisibilityEvents. Sostituire il codice nel file Connect.vb o Connect.cs con il codice di esempio riportato di seguito. Eseguire questo componente aggiuntivo, quindi aprire e poi chiudere la Finestra di comando e la Finestra di output nell'IDE Visual Studio per osservare il funzionamento dei metodi di acquisizione degli eventi. Per ulteriori informazioni sulla modalità di esecuzione degli esempi di automazione, vedere Procedura: compilare ed eseguire gli esempi di codice del modello a oggetti di automazione.
