방법: ToolStripControlHost를 사용하여 Windows Forms 컨트롤 래핑

아티클
05/04/2023

ToolStripControlHost는 ToolStripControlHost 생성자를 사용하거나 ToolStripControlHost 자체를 확장하여 임의 Windows Forms 컨트롤을 호스트할 수 있도록 디자인되었습니다. ToolStripControlHost를 확장하고 컨트롤의 자주 사용되는 속성과 메서드를 노출하는 속성 및 메서드를 구현하여 컨트롤을 래핑하는 방법이 더 간편합니다. ToolStripControlHost 수준에서 컨트롤에 대한 이벤트를 노출할 수도 있습니다.

파생을 통해 ToolStripControlHost에서 컨트롤을 호스트하려면 다음을 수행합니다.

ToolStripControlHost를 확장합니다. 원하는 컨트롤을 전달하는 기본 클래스 생성자를 호출하는 매개 변수가 없는 생성자를 구현합니다.

// 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

래핑된 컨트롤과 같은 형식의 속성을 선언하고 Control을 속성 접근자의 올바른 컨트롤 형식으로 반환합니다.

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

확장된 클래스의 속성 및 메서드와 함께 래핑된 컨트롤의 자주 사용되는 다른 속성 및 메서드를 노출합니다.

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

선택적으로 OnSubscribeControlEvents 및 OnUnsubscribeControlEvents 메서드를 재정의하고 노출할 컨트롤 이벤트를 추가합니다.

void OnSubscribeControlEvents( System::Windows::Forms::Control^ c )
{
   // Call the base so the base events are connected.
   __super::OnSubscribeControlEvents( c );
   
   // Cast the control to a MonthCalendar control.
   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 );
   
   // Cast the control to a MonthCalendar control.
   MonthCalendar^ monthCalendarControl = (MonthCalendar^)c;
   
   // Remove the event.
   monthCalendarControl->DateChanged -= gcnew DateRangeEventHandler( this, &ToolStripMonthCalendar::HandleDateChanged );
}

protected override void OnSubscribeControlEvents(Control c)
{
    // Call the base so the base events are connected.
    base.OnSubscribeControlEvents(c);

    // Cast the control to a MonthCalendar control.
    MonthCalendar monthCalendarControl = (MonthCalendar) c;

    // Add the event.
    monthCalendarControl.DateChanged +=
        new DateRangeEventHandler(OnDateChanged);
}

protected override void OnUnsubscribeControlEvents(Control c)
{
    // Call the base method so the basic events are unsubscribed.
    base.OnUnsubscribeControlEvents(c);

    // Cast the control to a MonthCalendar control.
    MonthCalendar monthCalendarControl = (MonthCalendar) c;

    // Remove the event.
    monthCalendarControl.DateChanged -=
        new DateRangeEventHandler(OnDateChanged);
}

Protected Overrides Sub OnSubscribeControlEvents(ByVal c As Control) 

    ' Call the base so the base events are connected.
    MyBase.OnSubscribeControlEvents(c)
    
    ' Cast the control to a MonthCalendar control.
    Dim monthCalendarControl As MonthCalendar = _
        CType(c, MonthCalendar)

    ' Add the event.
    AddHandler monthCalendarControl.DateChanged, _
        AddressOf HandleDateChanged

End Sub

Protected Overrides Sub OnUnsubscribeControlEvents(ByVal c As Control)
    ' Call the base method so the basic events are unsubscribed.
    MyBase.OnUnsubscribeControlEvents(c)

    ' Cast the control to a MonthCalendar control.
    Dim monthCalendarControl As MonthCalendar = _
        CType(c, MonthCalendar)

    ' Remove the event.
    RemoveHandler monthCalendarControl.DateChanged, _
        AddressOf HandleDateChanged

End Sub

노출할 이벤트에 필요한 래핑을 제공합니다.

// Declare the DateChanged event.
// Raise the DateChanged event.
void HandleDateChanged( Object^ sender, DateRangeEventArgs^ e )
{
   if ( DateChanged != nullptr )
   {
      DateChanged( this, e );
   }
}

// Declare the DateChanged event.
public event DateRangeEventHandler DateChanged;

// Raise the DateChanged event.
private void OnDateChanged(object sender, DateRangeEventArgs e)
{
    if (DateChanged != null)
    {
        DateChanged(this, e);
    }
}

    ' Declare the DateChanged event.
    Public Event DateChanged As DateRangeEventHandler

    ' Raise the DateChanged event.
    Private Sub HandleDateChanged(ByVal sender As Object, _
        ByVal e As DateRangeEventArgs)

        RaiseEvent DateChanged(Me, e)
