It handles inserting, deleting, moving, resizing, etc. of widgets. Normally multiple formwindows are used at the same time in the Designer. So each formwindow has its own undo/redo buffer, etc. Also the formwindow has some signals to inform e.g. about selection changes which is interesting for the PropertyEditor. For handling the events of the child widgets (moving, etc.) the handleMousePress(), etc. functions are called from the application event filter which is implemented in MainWindow::eventFilter(). */ FormWindow::FormWindow( FormFile *f, MainWindow *mw, QWidget *parent, const char *name ) : QWidget( parent, name, WDestructiveClose ), mainwindow( mw ), commands( 100 ), pixInline( TRUE ), pixProject( FALSE ) { ff = f; init(); initSlots(); } FormWindow::FormWindow( FormFile *f, QWidget *parent, const char *name ) : QWidget( parent, name, WDestructiveClose ), mainwindow( 0 ), commands( 100 ), pixInline( TRUE ) { ff = f; init(); } void FormWindow::init() { setWFlags(getWFlags() & Qt::WStyle_Maximize); fake = qstrcmp( name(), "qt_fakewindow" ) == 0; MetaDataBase::addEntry( this ); ff->setFormWindow( this ); iface = 0; proj = 0; propertyWidget = 0; toolFixed = FALSE; checkedSelectionsForMove = FALSE; mContainer = 0; startWidget = endWidget = 0; currTool = POINTER_TOOL; unclippedPainter = 0; widgetPressed = FALSE; drawRubber = FALSE; setFocusPolicy( ClickFocus ); sizePreviewLabel = 0; checkSelectionsTimer = new QTimer( this, "checkSelectionsTimer" ); connect( checkSelectionsTimer, SIGNAL( timeout() ), this, SLOT( invalidCheckedSelections() ) ); updatePropertiesTimer = new QTimer( this ); connect( updatePropertiesTimer, SIGNAL( timeout() ), this, SLOT( updatePropertiesTimerDone() ) ); showPropertiesTimer = new QTimer( this ); //!!!! connect( showPropertiesTimer, SIGNAL( timeout() ), this, SLOT( showPropertiesTimerDone() ) ); selectionChangedTimer = new QTimer( this ); connect( selectionChangedTimer, SIGNAL( timeout() ), this, SLOT( selectionChangedTimerDone() ) ); windowsRepaintWorkaroundTimer = new QTimer( this ); connect( windowsRepaintWorkaroundTimer, SIGNAL( timeout() ), this, SLOT( windowsRepaintWorkaroundTimerTimeout() ) ); insertParent = 0; connect( &commands, SIGNAL( undoRedoChanged( bool, bool, const QString &, const QString & ) ), this, SIGNAL( undoRedoChanged( bool, bool, const QString &, const QString & ) ) ); propShowBlocked = FALSE; setIcon( SmallIcon( "designer_form.png" , KDevDesignerPartFactory::instance()) ); connect( &commands, SIGNAL( modificationChanged( bool ) ), this, SLOT( modificationChanged( bool ) ) ); buffer = 0; QWidget *w = WidgetFactory::create( WidgetDatabase::idFromClassName( "QFrame" ), this ); setMainContainer( w ); propertyWidget = w; targetContainer = 0; hadOwnPalette = FALSE; defSpacing = BOXLAYOUT_DEFAULT_SPACING; defMargin = BOXLAYOUT_DEFAULT_MARGIN; hasLayoutFunc = FALSE; } void FormWindow::setMainWindow( MainWindow *w ) { mainwindow = w; MetaDataBase::addEntry( this ); initSlots(); } void FormWindow::initSlots() { if ( isFake() ) return; Q_ASSERT( project() || MainWindow::self ); if ( !project() && !MainWindow::self ) return; Project *p = project() ? project() : MainWindow::self->currProject(); if ( p && p->isCpp() ) { QString code = formFile()->code(); if ( code.isEmpty() ) formFile()->setCode( formFile()->codeComment() ); } } FormWindow::~FormWindow() { if ( MainWindow::self && MainWindow::self->objectHierarchy()->formWindow() == this ) MainWindow::self->objectHierarchy()->setFormWindow( 0, 0 ); MetaDataBase::clear( this ); if ( ff ) ff->setFormWindow( 0 ); delete iface; } void FormWindow::closeEvent( QCloseEvent *e ) { QGuardedPtr that = this; if ( ff->closeEvent() && ( !that || ( mainwindow && mainwindow->unregisterClient( this ) ) ) ) e->accept(); else e->ignore(); } void FormWindow::paintGrid( QWidget *w, QPaintEvent *e ) { if ( !mainWindow() || !mainWindow()->showGrid() ) return; QPixmap grid; QString grid_name; grid_name.sprintf("FormWindowGrid_%d_%d", mainWindow()->grid().x(), mainWindow()->grid().y()); if( !QPixmapCache::find( grid_name, grid ) ) { grid = QPixmap( 350 + ( 350 % mainWindow()->grid().x() ), 350 + ( 350 % mainWindow()->grid().y() ) ); grid.fill( colorGroup().color( QColorGroup::Foreground ) ); QBitmap mask( grid.width(), grid.height() ); mask.fill( color0 ); QPainter p( &mask ); p.setPen( color1 ); for ( int y = 0; y < grid.width(); y += mainWindow()->grid().y()) { for ( int x = 0; x < grid.height(); x += mainWindow()->grid().x() ) { p.drawPoint( x, y ); } } grid.setMask( mask ); QPixmapCache::insert( grid_name, grid ); } QPainter p( w ); p.setClipRegion( e->rect() ); p.drawTiledPixmap( QRect( 0, 0, width(), height() ), grid ); } /*!
