Nasıl yapılır: ToolStripControlHost ile Bir Windows Forms Denetimini Kaydırma

Makale
10/18/2023

ToolStripControlHost oluşturucuyu kullanarak ToolStripControlHost veya kendisini genişleterek rastgele Windows Forms denetimlerinin barındırılmasını ToolStripControlHost etkinleştirmek için tasarlanmıştır. Denetimin sık kullanılan özelliklerini ve yöntemlerini kullanıma sunan özellikleri ve yöntemleri genişletip ToolStripControlHost uygulayarak denetimi sarmalama daha kolaydır. Ayrıca, denetim ToolStripControlHost için olayları düzeyinde de kullanıma sunun.

Türetme yoluyla ToolStripControlHost'ta bir denetimi barındırmak için

genişletin ToolStripControlHost. İstenen denetimden geçen temel sınıf oluşturucuyu çağıran parametresiz bir oluşturucu uygulayın.

// Call the base constructor passing in a MonthCalendar instance.
ToolStripMonthCalendar() : ToolStripControlHost( gcnew MonthCalendar ) {}

// Call the base constructor passing in a MonthCalendar instance.
public ToolStripMonthCalendar() : base (new MonthCalendar()) { }

' Call the base constructor passing in a MonthCalendar instance.
Public Sub New() 
    MyBase.New(New MonthCalendar())

End Sub

Sarmalanmış denetimle aynı türde bir özellik bildirin ve özelliğin erişimcisinde doğru denetim türü olarak dönün Control .

property MonthCalendar^ MonthCalendarControl 
{
   MonthCalendar^ get()
   {
      return static_cast<MonthCalendar^>(Control);
   }
}

public MonthCalendar MonthCalendarControl
{
    get
    {
        return Control as MonthCalendar;
    }
}

Public ReadOnly Property MonthCalendarControl() As MonthCalendar 
    Get
        Return CType(Control, MonthCalendar)
    End Get
End Property

Genişletilmiş sınıftaki özellikler ve yöntemlerle sarmalanmış denetimin diğer sık kullanılan özelliklerini ve yöntemlerini kullanıma sunma.

property Day FirstDayOfWeek 
{
   // Expose the MonthCalendar.FirstDayOfWeek as a property.
   Day get()
   {
      return MonthCalendarControl->FirstDayOfWeek;
   }

   void set( Day value )
   {
      MonthCalendarControl->FirstDayOfWeek = value;
   }
}

// Expose the AddBoldedDate method.
void AddBoldedDate( DateTime dateToBold )
{
   MonthCalendarControl->AddBoldedDate( dateToBold );
}

// Expose the MonthCalendar.FirstDayOfWeek as a property.
public Day FirstDayOfWeek
{
    get
    {
        return MonthCalendarControl.FirstDayOfWeek;
    }
    set { MonthCalendarControl.FirstDayOfWeek = value; }
}

// Expose the AddBoldedDate method.
public void AddBoldedDate(DateTime dateToBold)
{
    MonthCalendarControl.AddBoldedDate(dateToBold);
}

' Expose the MonthCalendar.FirstDayOfWeek as a property.
Public Property FirstDayOfWeek() As Day 
    Get
        Return MonthCalendarControl.FirstDayOfWeek
    End Get
    Set
        MonthCalendarControl.FirstDayOfWeek = value
    End Set
End Property
 
' Expose the AddBoldedDate method.
Public Sub AddBoldedDate(ByVal dateToBold As DateTime) 
    MonthCalendarControl.AddBoldedDate(dateToBold)

End Sub

İsteğe bağlı olarak, ve yöntemlerini geçersiz kılın OnSubscribeControlEventsve OnUnsubscribeControlEvents kullanıma açmak istediğiniz denetim olaylarını ekleyin.

{
   // Call the base so the base events are connected.
   __super::OnSubscribeControlEvents( c );

   MonthCalendar^ monthCalendarControl = (MonthCalendar^)c;
   
   // Add the event.
   monthCalendarControl->DateChanged += gcnew DateRangeEventHandler( this, &ToolStripMonthCalendar::HandleDateChanged );
}

void OnUnsubscribeControlEvents( System::Windows::Forms::Control^ c )
{
   
   // Call the base method so the basic events are unsubscribed.
   __super::OnUnsubscribeControlEvents( c );
