L'esempio di codice seguente illustra la creazione di un menu di scelta rapida e l'uso del Show metodo . Per eseguire l'esempio, incollare il codice seguente in un modulo contenente un pulsante denominato Button1. Assicurarsi che tutti gli eventi siano associati ai metodi di gestione degli eventi.

// Displays the shortcut menu, offsetting its location 
// from the upper-left corner of Button1 by 20 pixels in each direction. 
void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   
   //Declare the menu items and the shortcut menu.
   array<MenuItem^>^menuItems = {gcnew MenuItem( "Some Button Info" ),gcnew MenuItem( "Some Other Button Info" ),gcnew MenuItem( "Exit" )};
   System::Windows::Forms::ContextMenu^ buttonMenu = gcnew System::Windows::Forms::ContextMenu( menuItems );
   buttonMenu->Show( Button1, System::Drawing::Point( 20, 20 ) );
}

// Displays the shortcut menu, offsetting its location 
// from the upper-left corner of Button1 by 20 pixels in each direction. 
private void Button1_Click(System.Object sender, System.EventArgs e)
{

    //Declare the menu items and the shortcut menu.
    MenuItem[] menuItems = new MenuItem[]{new MenuItem("Some Button Info"), 
        new MenuItem("Some Other Button Info"), new MenuItem("Exit")};

    ContextMenu buttonMenu = new ContextMenu(menuItems);
    buttonMenu.Show(Button1, new System.Drawing.Point(20, 20));
}

' Displays the shortcut menu, offsetting its location 
' from the upper-left corner of Button1 by 20 pixels in each direction. 
Private Sub Button1_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button1.Click

    'Declare the menu items and the shortcut menu.
    Dim menuItems() As MenuItem = New MenuItem() _
        {New MenuItem("Some Button Info"), _
        New MenuItem("Some Other Button Info"), _
        New MenuItem("Exit")}

    Dim buttonMenu As New ContextMenu(menuItems)
    buttonMenu.Show(Button1, New System.Drawing.Point(20, 20))
End Sub

Commenti

In genere, viene visualizzato un oggetto ContextMenu quando l'utente fa clic sul pulsante destro del mouse su un controllo o un'area del modulo a cui è ContextMenu associato. È possibile usare questo metodo per visualizzare manualmente il menu di scelta rapida in una posizione specifica e associarlo a un controllo specifico. Questo metodo non restituisce finché il menu non viene ignorato.
