National Alliance for Medical Image Computing Features Object-oriented C++ layer on top of Tcl/Tk Inherit from the VTK coding framework checkbutton.cb1.cb1 config -text "A checkbutton".cb1 deselect pack.cb1 vtkKWCheckButton *cb1 = vtkKWCheckButton::New(); cb1->SetParent(parent); cb1->Create(app); cb1->SetText("A checkbutton"); cb1->DeSelect(); app->Script("pack %s", cb1->GetWidgetName());

National Alliance for Medical Image Computing Features Can interact with Tcl/Tk from C++ app->Script("frame.myframe"); app->Script("pack.myframe"); vtkKWWidget *myframe = vtkKWWidget::New(); myframe->SetWidgetName(".myframe"); myframe->SetBackgroundColor(0.2, 0.5, 0.8); vtkKWCheckButton *cb = vtkKWCheckButton::New(); cb->SetParent(myframe); cb->Create(app); cb->SetCommand(NULL, ".myframe config –bg #223344"); app->Script("pack %s", cb->GetWidgetName());

National Alliance for Medical Image Computing Features Can interact and co-exist with Tcl/Tk directly from Tcl/Tk or Slicer Wrapped into a Tcl package just like VTK/ITK Fast-prototyping
