#include <TopTools_ListIteratorOfListOfShape.hxx>
#include <TopTools_HSequenceOfShape.hxx>
#include <IGESControl_Controller.hxx>
#include <IGESControl_Writer.hxx>
#include <IGESControl_Reader.hxx>
#include <TopoDS_Edge.hxx>
#include <TopoDS_Face.hxx>
MainWindow::MainWindow(QWidget *parent): QMainWindow(parent)
{ui.setupUi(this);occView = new occview(this);setCentralWidget(occView);InitMenu();
}
void MainWindow::InitMenu()
{QMenuBar* menuBar = ui.menuBar;QMenu* menuCreate = menuBar->addMenu(tr("&Create"));menuCreate->addAction(tr("&Box"));menuCreate->addAction(tr("&Sphere"));connect(menuBar, SIGNAL(triggered(QAction*)), this, SLOT(trigerMenu(QAction*)));
}TopoDS_Shape MainWindow::createBox()
{return BRepPrimAPI_MakeBox(10.0, 10.0, 10.0).Shape();
}
TopoDS_Shape MainWindow::createSphere()
{return BRepPrimAPI_MakeSphere(10.0).Shape();
}
void MainWindow::trigerMenu(QAction* action)
{if (action->text() == "&Box"){TopoDS_Shape box = createBox();Handle(AIS_Shape) aisBox = new AIS_Shape(box);occView->GetInteractiveContext()->Display(aisBox, Standard_True);occView->GetView()->FitAll();}else if (action->text() == "&Sphere"){TopoDS_Shape sphere = createSphere();Handle(AIS_Shape) aisSphere = new AIS_Shape(sphere);occView->GetInteractiveContext()->Display(aisSphere, Standard_True);occView->GetView()->FitAll();}else{QMessageBox::warning(this, tr("Warning"), action->text());}
}occview::occview(QWidget *parent): QWidget(parent)
{ui.setupUi(this);if (m_context.IsNull()) {Handle(Aspect_DisplayConnection) m_display_connection = new Aspect_DisplayConnection();if (m_graphic_driver.IsNull()){m_graphic_driver = new OpenGl_GraphicDriver(m_display_connection);}WId window_handle = (WId)winId();Handle(WNT_Window) wind = new WNT_Window((Aspect_Handle)window_handle);m_viewer = new V3d_Viewer(m_graphic_driver);m_view = m_viewer->CreateView();m_view->SetWindow(wind);if (!wind->IsMapped()) {wind->Map();}m_context = new AIS_InteractiveContext(m_viewer);
}
