I have an MDI application, working with just 1 document (for now).

I have several different classes of CView - FlamingoGanttView and FlamingoNavigatorView for example.

I have menu items to let the user add and remove these views.

Each view should appear only once.

 

At the moment, my MainFrame derives from CXTPMDIFrameWnd and contains a CXTPTabClientWnd m_MTIClientWnd and I keep a pointer to each view once it is create. This allows me to tick the menu item to say the view is on the screen.

 

At the moment, I have this code in the method behind the menu item.

 

void CMainFrame::OnViewsGanttChart()
{
 if (m_viewGantt != NULL)
 {
  // Don't know how to close the window yet.
 }
 else
 {
  CMDIChildWnd* pActiveChild = MDIGetActive();
  CDocument* pDocument= pActiveChild->GetActiveDocument()) == NULL)

  CMultiDocTemplate docTemplate(IDR_GanttTYPE,
  RUNTIME_CLASS(CFlamingoDoc),
  RUNTIME_CLASS(CChildFrame), // custom MDI child frame
  RUNTIME_CLASS(FlamingoGanttView));

  CChildFrame *newChild = (CChildFrame*) docTemplate.CreateNewFrame(pDocument, NULL);
  docTemplate.InitialUpdateFrame(newChild, pDocument);

  CCreateContext context;
  context.m_pCurrentFrame = newChild;
  context.m_pCurrentDoc = pDocument;
  context.m_pNewViewClass = RUNTIME_CLASS(FlamingoGanttView);
  context.m_pNewDocTemplate = &docTemplate;

  m_viewGantt = (FlamingoGanttView*) CreateView(&context, IDGT_VIEW_GANTT);

  SetActiveView(m_viewGantt, TRUE);
  m_viewGantt->ShowWindow(SW_SHOW);
  m_viewGantt->SetWindowText("Gantt Chart");
 }
}

 

My first question is, does this sound like the best way to implement a tabbed main area?

Second question - how do I change the name of the tab - they are both getting called "Navigator1". I would like "Navigator" and "Gantt Chart" at the tab names.
Third question - how do I close these views and tabs? I have a pointer to the view, but CloseWindow and DestroyWindow don't do anything.
