Tutorial 5:  Wrapping a Frame around our Scribble Application

This is the code we use to produce a simple frame application.  We inherit a class called CMainframe from the CFrame class in Win32++. Notice how we use the SetView function to specify the "view" window of our frame. This "view" window happens to be the same code as the simple scribble application shown in the previous tutorial.  In this way, we wrap a frame around our previous scribble application.

The CMainFrame class inherits OnCommand from CFrame.  This function responds to input from the frame's menu and toolbar. We haven't implemented many of these inputs yet, so at this stage most of them simply display a simple message box.

CMainFrame::CMainFrame()
{
  //Set m_View as the view window of the frame
  SetView(m_View);
}

BOOL CMainFrame::OnCommand(WPARAM wParam, LPARAM lParam)
{
  // Process the messages from the Menu and Tool Bar
  switch (LOWORD(wParam))
  {
  case IDM_FILE_EXIT:
    // End the application
    ::PostMessage(m_hWnd, WM_CLOSE, 0, 0);
    return TRUE;
  case IDM_HELP_ABOUT:
    // Display the help dialog
    OnHelp();
    return TRUE;
  case IDM_FILE_NEW:
    ::MessageBox(NULL, _T("File New  ... Implemented later"), _T("Menu"), MB_OK);
    return TRUE;
  case IDM_FILE_OPEN:
    ::MessageBox(NULL, _T("File Open  ... Implemented later"), _T("Menu"), MB_OK);
    return TRUE;
  case IDM_FILE_SAVE:
    ::MessageBox(NULL, _T("File Save  ... Implemented later"), _T("Menu"), MB_OK);
    return TRUE;
  case IDM_FILE_SAVEAS:
    ::MessageBox(NULL, _T("File SaveAs  ... Implemented later"), _T("Menu"), MB_OK);
    return TRUE;
  case IDM_FILE_PRINT:
    ::MessageBox(NULL, _T("File Print  ... Implemented later"), _T("Menu"), MB_OK);
    return TRUE;
  }

  return FALSE;
}
