The workspace itself contains zero, one or more - document windows, each of which is a widget. - - The workspace itself is an ordinary TQt widget. It has a standard - constructor that takes a parent widget and an object name. The - parent window is usually a TQMainWindow, but it need not be. - - Document windows (i.e. MDI windows) are also ordinary TQt widgets - which have the workspace as their parent widget. When you call - show(), hide(), showMaximized(), setCaption(), etc. on a document - window, it is shown, hidden, etc. with a frame, caption, icon and - icon text, just as you'd expect. You can provide widget flags - which will be used for the tqlayout of the decoration or the - behaviour of the widget itself. - - To change or retrieve the tqgeometry of MDI windows you must operate - on the MDI widget's parentWidget(). (The parentWidget() provides - access to the decorated window in which the MDI window's widget is - shown.) - - A document window becomes active when it gets the keyboard focus. - You can also activate a window in code using setFocus(). The user - can activate a window by moving focus in the usual ways, for - example by clicking a window or by pressing Tab. The workspace - emits a signal windowActivated() when it detects the activation - change, and the function activeWindow() always returns a pointer - to the active document window. - - The convenience function windowList() returns a list of all - document windows. This is useful to create a popup menu - "<u>W</u>indows" on the fly, for example. - - TQWorkspace provides two built-in tqlayout strategies for child - windows: cascade() and tile(). Both are Q_SLOTS so you can easily - connect menu entries to them. - - If you want your users to be able to work with document windows - larger than the actual workspace, set the scrollBarsEnabled - property to TRUE. - - If the top-level window contains a menu bar and a document window - is maximised, TQWorkspace moves the document window's minimize, - restore and close buttons from the document window's frame to the - workspace window's menu bar. It then inserts a window operations - menu at the far left of the menu bar. -*/ - -static bool inCaptionChange = FALSE; - -class TQWorkspaceChild : public TQFrame -{ - Q_OBJECT - TQ_OBJECT - - friend class TQWorkspace; - friend class TQTitleBar; - -public: - TQWorkspaceChild( TQWidget* window, - TQWorkspace* parent=0, const char* name=0 ); - ~TQWorkspaceChild(); - - void setActive( bool ); - bool isActive() const; - - void adjustToFullscreen(); - - void setqStatusBar(TQStatusBar *); - TQWidget* windowWidget() const; - TQWidget* iconWidget() const; - - void doResize(); - void doMove(); - - TQSize tqsizeHint() const; - TQSize tqminimumSizeHint() const; - - TQSize baseSize() const; - -Q_SIGNALS: - void showOperationMenu(); - void popupOperationMenu( const TQPoint& ); - -public Q_SLOTS: - void activate(); - void showMinimized(); - void showMaximized(); - void showNormal(); - void showShaded(); - void setCaption( const TQString& ); - void internalRaise(); - void titleBarDoubleClicked(); - - void move( int x, int y ); - -protected: - bool event(TQEvent * ); - void enterEvent( TQEvent * ); - void leaveEvent( TQEvent * ); - void childEvent( TQChildEvent* ); - void resizeEvent( TQResizeEvent * ); - void moveEvent( TQMoveEvent * ); - bool eventFilter( TQObject *, TQEvent * ); - - bool focusNextPrevChild( bool ); - - void drawFrame( TQPainter * ); - void styleChange( TQStyle & ); - -private: - TQWidget* childWidget; - TQGuardedPtr<TQWidget> lastfocusw; - TQWidgetResizeHandler *widgetResizeHandler; - TQTitleBar* titlebar; - TQGuardedPtr<TQStatusBar> statusbar; - TQGuardedPtr<TQTitleBar> iconw; - TQSize windowSize; - TQSize shadeRestore; - TQSize shadeRestoreMin; - bool act :1; - bool shademode :1; - bool snappedRight :1; - bool snappedDown :1; -#if defined(TQ_DISABLE_COPY) // Disabled copy constructor and operator= - TQWorkspaceChild( const TQWorkspaceChild & ); - TQWorkspaceChild &operator=( const TQWorkspaceChild & ); -#endif -}; - -class TQMainWindow; - -class TQWorkspacePrivate { -public: - TQWorkspaceChild* active; - TQPtrList<TQWorkspaceChild> windows; - TQPtrList<TQWorkspaceChild> focus; - TQPtrList<TQWidget> icons; - TQWorkspaceChild* maxWindow; - TQRect maxRestore; - TQGuardedPtr<TQFrame> maxcontrols; - TQGuardedPtr<TQMenuBar> maxmenubar; - - int px; - int py; - TQWidget *becomeActive; - TQGuardedPtr<TQLabel> maxtools; - TQPopupMenu* popup; - TQPopupMenu* toolPopup; - int menuId; - int controlId; - TQString topCaption; - - TQScrollBar *vbar, *hbar; - TQWidget *corner; - int yoffset, xoffset; - - // toplevel mdi fu - TQWorkspace::WindowMode wmode; - TQGuardedPtr<TQMainWindow> mainwindow; - TQPtrList<TQDockWindow> dockwindows, newdocks; -}; - -static bool isChildOf( TQWidget * child, TQWidget * parent ) -{ - if ( !parent || !child ) - return FALSE; - TQWidget * w = child; - while( w && w != parent ) - w = w->parentWidget(); - return w != 0; -} - -/*! - Constructs a workspace with a \a parent and a \a name. -*/ -TQWorkspace::TQWorkspace( TQWidget *parent, const char *name ) - : TQWidget( parent, name ) -{ - init(); -} - -#ifdef TQT_WORKSPACE_WINDOWMODE -/*! - Constructs a workspace with a \a parent and a \a name.
