I have tried the new code. There are not errors in the prompt, but the
boxWidget still doesn't work. It seems like boxWidget and the cone are not
well connected.
The final code that I have after using "run":
(ns example
(:import (javax.swing JFrame JPanel SwingUtilities)))
(clojure.lang.RT/loadLibrary "vtkCommonJava")
(clojure.lang.RT/loadLibrary "vtkWidgetsJava")
(def boxWidget (vtk.vtkBoxWidget.))
(def myCallback
(fn []
(let [t (vtk.vtkTransform.)]
(.GetTransform t)
(-> boxWidget .GetProp3D (.SetUserTransform t)))))
(defn main []
(let [cone (vtk.vtkConeSource.)
coneMapper (vtk.vtkPolyDataMapper.)
coneActor (vtk.vtkActor.)
ren (vtk.vtkRenderer.)
renWin (vtk.vtkRenderWindow.)
iren (vtk.vtkRenderWindowInteractor.)
style (vtk.vtkInteractorStyleTrackballCamera.)
t (vtk.vtkTransform.)]
(doto cone
(.SetHeight 3.0)
(.SetRadius 1.0)
(.SetResolution 10))
(doto coneMapper
(.SetInputConnection (.GetOutputPort cone)))
(doto coneActor
(.SetMapper coneMapper))
(doto ren
(.GradientBackgroundOn)
(.SetBackground 0.5 0.6 0.8)
(.AddActor coneActor)
(.ResetCamera))
(doto renWin
(.AddRenderer ren)
(.SetSize 300 300))
(doto iren
(.SetRenderWindow renWin)
(.SetInteractorStyle style))
(doto boxWidget
(.SetInteractor iren)
(.SetPlaceFactor 1.25)
(.SetProp3D coneActor)
(.PlaceWidget)
(.AddObserver "interactionEvent" myCallback "run")
(.On))
(doto iren
(.Initialize)
(.Start))))
(example/main)
