/**
  * @short Base class for all your special main frames.
  *
  * It contains the child frame area (QMainWindow's central widget) and a child view taskbar
  * for switching the MDI views. Most methods are virtual functions for later overriding.
  *
  * Basically, this class provides functionality for docking/undocking view windows and
  * manages the taskbar. Usually the programmer just need to know about this class and the child view class.
  *
  * Your program mainwidget should inherit KMdiMainFrm. Then usually you'll just need
  * addWindow() and removeWindowFromMdi() to control the views.
  *   \code
  *   class MyMainWindow : public KMdiMainFrm
  *   { .... };
  *   ...
  *   MyMainWindow mainframe;
  *   qApp->setMainWidget(&mainframe);
  *   mainframe->addWindow(view1); // put it under MDI control
  *   mainframe->addWindow(view2);
  *   \endcode
  *
  * Most public and protected methods of this class are for program calls of the actions
  * the user could click.<br>
  *
  * Dynamic switching the MDI mode can be done via switchToChildframeMode(), switchToToplevelMode(),
  * switchToTabPageMode() or fakeSDIApplication() or asked via mdiMode(), isFakingSDIApplication().
  *
  * This class provides already the "Window" menu needed in common MDI applications. Just
  * insert it in your main menu:
  * \code
  * if (!isFakingSDIApplication()) {
  *    menuBar()->insertItem( tr("&Window"), windowMenu());
  * }
  * \endcode
  *
  * Synchronize the positions of the MDI control buttons inserted in your mainmenu:
  * \code
  * void B_MainModuleWidget::initMenuBar()
  * {
  *   setMenuForSDIModeSysButtons( menuBar());
  * ...
  * void B_MainModuleWidget::resizeEvent ( QResizeEvent *e)
  * {
  *   KMdiMainFrm::resizeEvent( e);
  *   setSysButtonsAtMenuPosition();
  * }
  * \endcode
  *
  * You can dynamically change the shape of the attached MDI views using setFrameDecorOfAttachedViews().
  *
  * Additionally, here's a hint how to restore the mainframe's settings from config file:
  * \code
  *
  *    // restore MDI mode (toplevel, childframe, tabpage)
  *    int mdiMode = config->readIntEntry( "mainmodule session", "MDI mode", KMdi::ChildframeMode);
  *    switch (mdiMode) {
  *    case KMdi::ToplevelMode:
  *       {
  *          int childFrmModeHt = config->readIntEntry( "mainmodule session", "Childframe mode height", desktop()->height() - 50);
  *          mainframe->resize( m_pMdiMainFrm->width(), childFrmModeHt);
  *          mainframe->switchToToplevelMode();
  *       }
  *       break;
  *    case KMdi::ChildframeMode:
  *       break;
  *    case KMdi::TabPageMode:
  *       {
  *          int childFrmModeHt = m_pCfgFileManager->readIntEntry( "mainmodule session", "Childframe mode height", desktop()->height() - 50);
  *          mainframe->resize( m_pMdiMainFrm->width(), childFrmModeHt);
  *          mainframe->switchToTabPageMode();
  *       }
  *       break;
  *    default:
  *       break;
  *    }
  *
  *    // restore a possible maximized Childframe mode
  *    bool maxChildFrmMode = config->readBoolEntry( "mainmodule session", "maximized childframes", true);
  *    mainframe->setEnableMaximizedChildFrmMode(maxChildFrmMode);
  * \endcode
  * The maximized-Childframe mode means that currently all views are maximized in Childframe mode's application desktop.
  *
  * This class provides placing algorithms in Childframe mode. Call tilePragma(), tileAnodine(), tileVertically(),
  * cascadeWindows(), cascadeMaximized(), expandVertical(), expandHorizontal() for those actions.
  *
  * activateView(KMdiChildView*) and activateView(int index) set the appropriate MDI child view as the active
  * one. It will be raised, gets an active MDI frame and gets the focus. Call activeView() to find out what the
  * current MDI view is.
  *
  * Use detachWindow() and attachWindow() for docking the MDI views to desktop and back.
  *
  * Connect accels of your program with activatePrevWin(), activateNextWin() and activateView(int index).
  *
  * Note: KMdiChildViews can be added in 2 meanings: Either as a normal child view (usually containing
  * user document views) or as a tool-view (usually containing status, info or control widgets).
  * The tool-views can be added as floating dockwidgets or as stay-on-top desktop windows in tool style.
  *
  * Here's an example how you can suggest things for the adding of views to the MDI control via flags:
  * \code
  * m_mapOfMdiWidgets.insert( pWnd, mh);
  * unsigned int mdiFlags = KMdi::StandardAdd;
  * if( !bShow)
  *    mdiFlags |= KMdi::Hide;
  * if( !bAttach)
  *    mdiFlags |= KMdi::Detach;
  * if( bMinimize)
  *    mdiFlags |= KMdi::Minimize;
  * if( bToolWindow)
  *    mdiFlags |= KMdi::ToolWindow;
  * if (m_pMdiMainFrm->isFakingSDIApplication()) {
  *    if (bAttach) { // fake an SDI app
  *       mdiFlags |= KMdi::Maximize;
  *    }
  *    else {
  *       m_pMdiMainFrm->addWindow( pWnd, QPoint(20, 20), KMdi::AddWindowFlags(mdiFlags));
  *       return;
  *    }
  * }
  * m_pMdiMainFrm->addWindow( pWnd, KMdi::AddWindowFlags(mdiFlags));
  * \endcode
  *
  * Further note: Pay attention to the fact that when you click on the close button of MDI views that their
  * close event should be redirected to closeWindow(). Otherwise the mainframe class will
  * not get noticed about the deleted view and a dangling pointer will remain in the MDI control. The
  * closeWindow() or the removeWindowFromMdi() method is for that issue. The difference is closeWindow()
  * deletes the view object. So if your application wants to control that by itself, call removeWindowFromMdi()
  * and call delete by yourself. See also KMdiChildView::closeEvent() for tat issue.
