Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkQtView.

const

void vtkQtTreeView::PrintSelf ( ostream &  os, vtkIndent  indent  )

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkView.

QWidget* vtkQtTreeView::GetWidget ( )

overridevirtual

Get the main container of this view (a QWidget).

The application typically places the view with a call to GetWidget(): something like this this->ui->box->layout()->addWidget(this->View->GetWidget());
