[vtkusers] How to compare vtk widget

[Jose Barreto]

I use something like this:


	list<vtkSmartPointer<vtkAbstractWidget>> vectorWindget;

	vtkTextoSetaWidget* texto0 = vtkTextoSetaWidget::New();
	vtkTextoSetaWidget* texto1 = vtkTextoSetaWidget::New();

	vtkReguaWidget* regua0 = vtkReguaWidget::New();
	vtkReguaWidget* regua1 = vtkReguaWidget::New();

	vectorWindget.push_back(texto0);
	vectorWindget.push_back(texto1);

	vectorWindget.push_back(regua0);
	vectorWindget.push_back(regua1);


	//procura o texto 1
	for (std::list<vtkSmartPointer<vtkAbstractWidget>>::iterator it =
vectorWindget.begin(); it != vectorWindget.end(); ++it)
	{
		if (it->GetPointer() != nullptr)
		{
			if ((gcnew
String(it->GetPointer()->GetClassName()))->Equals("vtkTextoSetaWidget")
				&&
(XDicom::Anotacoes::vtkTextoSetaWidget::SafeDownCast(it->GetPointer()) ==
texto1))
			{
				vectorWindget.remove(texto1);
				break;
			}
		}
	}


My list has objects as vtkabstractwidget because I have more than one type
of widget it.

so check if the class name and the same for which I am convertanto to avoid
mistakes.
