Unsolved Opencascade visualization in QT
-
Hi everyone,
I am trying to execute an opencascade example: "MakeBottle". This example returns a TopoDS_Shape. I have been able to compile but I am not see any bottle. The qt window is empty. You can find the code below:
int main(int argc, char *argv[]) { QApplication a(argc, argv); // create a Qt window QWidget *window = new QWidget(); // create a bottle (TopoDS_Shape) TopoDS_Shape myBottle = MakeBottle(70., 120., 30.); // th DisplayDonnection Handle(Aspect_DisplayConnection) aDisplayConnection; // the GraphicDriver Handle(OpenGl_GraphicDriver) aGraphicDriver = new OpenGl_GraphicDriver(aDisplayConnection); // creating the Viewer Handle(V3d_Viewer) aViewer = new V3d_Viewer(aGraphicDriver, Standard_ExtString("my3dViewer")); // creating a View Handle(V3d_View) aView = aViewer->CreateView(); Handle(WNT_Window) wind = new WNT_Window((Aspect_Handle)window->winId()); // the Interactive context Handle(AIS_InteractiveContext) aContext = new AIS_InteractiveContext(aViewer); Handle(AIS_Shape) anAISShape = new AIS_Shape(myBottle); aContext->Display(anAISShape, true); aView->SetWindow(wind); window->show(); return a.exec(); }
Thanks in advance.
Kind regards.

Hi,
OpenCascade is providing Qt examples, did you try them ?

I guess the problem is rather related to the setup of the OpenGl context for the viewer or something like that than to OCCT. What OS are you on?
