+/**
+ * @short Base class for all your special view windows.
+ *
+ * Base class for all MDI view widgets. KMdi stores additional information in this class
+ * to handle the attach/detach mechanism and such things.
+ *
+ * All such windows 'lives' attached to a KMdiChildFrm widget
+ * managed by KMdiChildArea, or detached (managed by the window manager.)
+ * So remember that the KMdiChildView::parent pointer may change, and may be 0L, too.
+ *
+ * There are 2 possibilities for you to put your widgets under MDI control:
+ *
+ * Either you inherit all the views from KMdiChildView:
+ * \code
+ * class MyMdiWidget : public KMdiChildView
+ * { .... };
+ * ...
+ * MyMdiWidget w;
+ * mainframe->addWindow(w, flags);
+ * \endcode
+ *
+ * or you wrap them by a KMdiChildView somehow like this:
+ *
+ * \code
+ * void DocViewMan::addKMdiFrame(TQWidget* pNewView, bool bShow, const TQPixmap& icon)
+ * {
+ * // cover it by a KMdi childview and add that MDI system
+ * KMdiChildView* pMDICover = new KMdiChildView( pNewView->caption());
+ * pMDICover->setIcon(icon);
+ * m_MDICoverList.append( pMDICover);
+ * TQBoxLayout* pLayout = new TQHBoxLayout( pMDICover, 0, -1, "layout");
+ * pNewView->reparent( pMDICover, TQPoint(0,0));
+ * pLayout->addWidget( pNewView);
+ * pMDICover->setName( pNewView->name());
+ * // captions
+ * TQString shortName = pNewView->caption();
+ * int length = shortName.length();
+ * shortName = shortName.right(length - (shortName.findRev('/') +1));
+ * pMDICover->setTabCaption( shortName);
+ * pMDICover->setCaption(pNewView->caption());
+ *
+ * // fake a viewActivated to update the currentEditView/currentBrowserView pointers _before_ adding to MDI control
+ * slot_viewActivated( pMDICover);
+ *
+ * // take it under MDI mainframe control (note: this triggers also a setFocus())
+ * int flags;
+ * if (bShow) {
+ * flags = KMdi::StandardAdd;
+ * }
+ * else {
+ * flags = KMdi::Hide;
+ * }
+ * // set the accelerators for Toplevel MDI mode (each toplevel window needs its own accels
+ * connect( m_pParent, TQT_SIGNAL(childViewIsDetachedNow(TQWidget*)), this, TQT_SLOT(initKeyAccel(TQWidget*)) );
+ *
+ * m_pParent->addWindow( pMDICover, flags);
+ * // correct the default settings of KMdi ('cause we haven't a tab order for subwidget focuses)
+ * pMDICover->setFirstFocusableChildWidget(0L);
+ * pMDICover->setLastFocusableChildWidget(0L);
+ * }
