What is KWWidgets ?

• A GUI toolkit– Cross-platform

– Open-license

– Free


What is KWWidgets ?

• A GUI toolkit that provides low-level and high-level visualization-oriented widgets

Vs.


What is KWWidgets ?

• Over 100 C++ classes used by Kitware to develop complete open-source and commercial end-user applications for more than 7 years


What is KWWidgets ?


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());


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());


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


Features

vtkKWCheckButton *cb1 = vtkKWCheckButton::New();cb1->SetParent(parent);cb1->Create(app);

cb1->SetText("A checkbutton");

cb1->DeSelect();

app->Script("pack %s", cb1->GetWidgetName());

package require kwwidgets

vtkKWCheckButton cb1cb1 SetParent $parentcb1 Create $app

cb1 SetText "A checkbutton"

cb1 DeSelect

pack [cb1 GetWidgetName]

…

button .b -text "My Button"pack .b


Features

• Testable– Use CMake/CTest/Dashboard framework

– Trace framework
