virtual vtkTypeBool vtkQtSQLDatabase::IsA ( const char *  name)
virtual

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.

◆ PrintSelf()

void vtkQtSQLDatabase::PrintSelf ( ostream &  os,
vtkIndent  indent

Reimplemented from vtkObject.
