#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);
}
