If you want to always generate the same window you should call ‘invoke nomad tab’ to instantiate a SDockTab instead.
There’s some usage cases inside of engine source code.

I solved my problem. Here it is.


TSharedPtr<SWindow> ParentWindow = MainFrameModule.GetParentWindow();

        if (ParentWindow.IsValid() && OpenWindow.IsValid()==false)
        {
            //Açılan  pencereyi bir değişkene tanımlandı.
            OpenWindow=FSlateApplication::Get().AddWindowAsNativeChild(MyToolBarWindow.ToSharedRef(), ParentWindow.ToSharedRef());


            //GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, TEXT("active window"));



        }
        else {

            OpenWindow.Get()->DestroyWindowImmediately();//açılan pencere destroy edildi.
            OpenWindow.Reset();        //değişken sıfırlandı.


        }
