Base class for all MDI view widgets. QextMDI stores additional information in this class to handle the attach/detach mechanism and such things.
All such windows 'lives' attached to a QextMdiChildFrm widget managed by QextMdiChildArea, or detached (managed by the window manager.) So remember that the QextMdiChildView::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 QextMdiChildView:
class MyMdiWidget : public QextMdiChildView { .... }; ... MyMdiWidget w; mainframe->addWindow(w, flags); |
or you wrap them by a QextMdiChildView somehow like this:
void DocViewMan::addQExtMDIFrame(QWidget* pNewView, bool bShow, const QPixmap& icon) { // cover it by a QextMDI childview and add that MDI system QextMdiChildView* pMDICover = new QextMdiChildView( pNewView->caption()); pMDICover->setIcon(icon); m_MDICoverList.append( pMDICover); QBoxLayout* pLayout = new QHBoxLayout( pMDICover, 0, -1, "layout"); pNewView->reparent( pMDICover, QPoint(0,0)); pLayout->addWidget( pNewView); pMDICover->setName( pNewView->name()); // captions QString 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 = QextMdi::StandardAdd; } else { flags = QextMdi::Hide; } // set the accelerators for Toplevel MDI mode (each toplevel window needs its own accels connect( m_pParent, SIGNAL(childViewIsDetachedNow(QWidget*)), this, SLOT(initKeyAccel(QWidget*)) ); m_pParent->addWindow( pMDICover, flags); // correct the default settings of QextMDI ('cause we haven't a tab order for subwidget focuses) pMDICover->setFirstFocusableChildWidget(0L); pMDICover->setLastFocusableChildWidget(0L); } |

Constructor
QextMdiChildView ( QWidget* parentWidget = 0L, const char* name = 0L, WFlags f=0)
| QextMdiChildView |
Constructor 2 (sets "Unnamed" as default caption)
~QextMdiChildView ()
| ~QextMdiChildView |
Destructor
void activate ()
| activate |
This method does the same as focusInEvent(). That's why it is a replacement for the setFocus() call. It makes sense if you for instance want to focus (I mean raise and activate) this view although the real focus is in another toplevel widget. focusInEvent() will never get called in that case and your setFocus() call for this widget would fail without any effect. Use this method with caution, it always raises the view and pushes the taskbar button. Also when the focus is still on another MDI view in the same toplevel window where this is located!
void setFirstFocusableChildWidget (QWidget*)
| setFirstFocusableChildWidget |
Memorizes the first focusable child widget of this widget

const QString& caption ()
| caption |
[const]

void setMDICaption (const QString &caption)
| setMDICaption |
[virtual]
Sets the caption of both, window and button on the taskbar (they are going to be the same)
QextMdiChildFrm * mdiParent ()
| mdiParent |
[const]
Returns the QextMdiChildFrm parent widget (or 0 if the window is not attached)
bool isMinimized ()

[const]
Returns the geometry of this MDI child window as QWidget::geometry() does.
void setInternalGeometry (const QRect& newGeomety)
| setInternalGeometry |
Sets the geometry of the client area of this MDI child window. The top left position of the argument is the position of the top left point of the client area in its parent coordinates and the arguments width and height is the width and height of the client area. Please note: This differs from the behaviour of QWidget::setGeometry()!
QRect externalGeometry ()
| externalGeometry |
[const]
Returns the frame geometry of this window or of the parent if there is any...
void setExternalGeometry (const QRect& newGeomety)
| setExternalGeometry |
Sets the geometry of the frame of this MDI child window. The top left position of the argument is the position of the top left point of the frame in its parent coordinates and the arguments width and height is the width and height of the widget frame.

QPixmap* myIconPtr ()
| myIconPtr |
[virtual]
You should override this function in the derived class.

[virtual]
Minimizes this window when it is attached to the Mdi manager. Otherwise has no effect
void maximize (bool bAnimate)

[virtual]

QRect restoreGeometry ()

[virtual]
Sets the maximum size of the widget to w by h pixels. It extends it base clase method in a way that the maximum size of its childframe (if there is one) will be set, additionally.
bool isToolView ()
| isToolView |
[const]
Returns if this is added as MDI tool-view
void attach ()
| attach |
[virtual slot]
Attaches this window to the Mdi manager. It calls the QextMdiMainFrm attachWindow function , so if you have a pointer to this QextMdiMainFrm you'll be faster calling that function. Useful as slot.
void detach ()
| detach |
[virtual slot]
Detaches this window from the Mdi manager. It calls the QextMdiMainFrm detachWindow function , so if you have a pointer to this QextMdiMainFrm you'll be faster calling that function. Useful as slot.
void minimize ()
| minimize |
[virtual slot]
Mimimizes the MDI view. If attached, the covering childframe widget is minimized (only a mini widget showing the caption bar and the system buttons will remain visible). If detached, it will use the minimize of the underlying system ( QWidget::showMinimized ).
void maximize ()
| maximize |
[virtual slot]
Maximizes the MDI view. If attached, this widget will fill the whole MDI view area widget. The system buttons move to the main menubar (if set by QextMdiMainFrm::setMenuForSDIModeSysButtons ). If detached, it will use the minimize of the underlying system (QWidget::showMaximized ).
void restore ()
| restore |
[virtual slot]
Restores this window to its normal size. Also known as 'normalize'.
void youAreAttached (QextMdiChildFrm *lpC)
| youAreAttached |
[virtual slot]

void youAreDetached ()
| youAreDetached |
[virtual slot]
Internally called, if QextMdiMainFrm::detach is called. Some things for going toplevel will be done here.
void slot_clickedInWindowMenu ()

| slot_clickedInDockMenu |
[virtual slot]
Called if someone click on the "Dock/Undock..." menu item for this child frame window
void show ()
| show |
[virtual slot]
Calls QWidget::show but also for it's parent widget if attached
void hide ()
| hide |
[virtual slot]
Calls QWidget::hide() or it's parent widget hide() if attached
void showMinimized ()
| showMinimized |
[virtual slot]
Overridden from its base class method. Emits a signal QextMdiChildView::isMinimizedNow , additionally. Note that this method is not used by an external windows manager call on system minimizing.
void showMaximized ()
| showMaximized |
[virtual slot]
Overridden from its base class method. Emits a signal QextMdiChildView::isMaximizedNow , additionally. Note that this method is not used by an external windows manager call on system maximizing.
void showNormal ()
| showNormal |
[virtual slot]
Overridden from its base class method. Emits a signal QextMdiChildView::isRestoredNow , additionally. Note that this method is not used by an external windows manager call on system normalizing.
void closeEvent (QCloseEvent *e)
| closeEvent |
[protected virtual]
Ignores the event and calls QextMdiMainFrm::childWindowCloseRequest instead. This is because the mainframe has control over the views. Therefore the MDI view has to request the mainframe for a close.
bool eventFilter (QObject *obj, QEvent *e)
| eventFilter |
[protected virtual]
It only catches QEvent::KeyPress events there. If a Qt::Key_Tab is pressed, the internal MDI focus handling is called. That means if the last focusable child widget of this is called, it will jump to the first focusable child widget of this. See QextMdiChildView::setFirstFocusableChildWidget and QextMdiChildView::lastFirstFocusableChildWidget
void focusInEvent (QFocusEvent *e)
| focusInEvent |
[protected virtual]
If attached, the childframe will be activated and the MDI taskbar button will be pressed. Additionally, the memorized old focused child widget of this is focused again. Sends the focusInEventOccurs signal befor changing the focus and the gotFocus signal after changing the focus.
void focusOutEvent (QFocusEvent *e)
| focusOutEvent |
[protected virtual]
Send the lostFocus signal
void resizeEvent (QResizeEvent *e)
| resizeEvent |
[protected virtual]
Internally used for the minimize/maximize/restore mechanism when in attach mode.
