Simply by using QPEApplication instead of QApplication, a standard Qt application becomes a Qtopia application. It automatically follows style changes, quits and raises, and in the case of \link docwidget.html document-oriented\endlink applications, changes the currently displayed document in response to the environment. To create a \link docwidget.html document-oriented\endlink application use showMainDocumentWidget(); to create a non-document-oriented application use showMainWidget(). The keepRunning() function indicates whether the application will continue running after it's processed the last \link qcop.html QCop\endlink message. This can be changed using setKeepRunning(). A variety of signals are emitted when certain events occur, for example, timeChanged(), clockChanged(), weekChanged(), dateFormatChanged() and volumeChanged(). If the application receives a \link qcop.html QCop\endlink message on the application's QPE/Application/\e{appname} channel, the appMessage() signal is emitted. There are also flush() and reload() signals, which are emitted when synching begins and ends respectively - upon these signals, the application should save and reload any data files that are involved in synching. Most of these signals will initially be received and unfiltered through the appMessage() signal. This class also provides a set of useful static functions. The qpeDir() and documentDir() functions return the respective paths. The grabKeyboard() and ungrabKeyboard() functions are used to control whether the application takes control of the device's physical buttons (e.g. application launch keys). The stylus' mode of operation is set with setStylusOperation() and retrieved with stylusOperation(). There are also setInputMethodHint() and inputMethodHint() functions. \ingroup qtopiaemb */ class QPEApplication : public QApplication { Q_OBJECT public: QPEApplication( int& argc, char **argv, Type=GuiClient ); ~QPEApplication(); static QString qpeDir(); static QString documentDir(); void applyStyle(); void reset(); static int defaultRotation(); static void setDefaultRotation(int r); static void setCurrentRotation(int r); static void setCurrentMode(int x, int y, int depth ); static void grabKeyboard(); static void ungrabKeyboard(); enum StylusMode { LeftOnly, RightOnHold // RightOnHoldLeftDelayed, etc. }; static void setStylusOperation( QWidget*, StylusMode ); static StylusMode stylusOperation( QWidget* ); enum InputMethodHint { Normal, AlwaysOff, AlwaysOn }; enum screenSaverHint { Disable = 0, DisableLightOff = 1, DisableSuspend = 2, Enable = 100 }; static void setInputMethodHint( QWidget *, InputMethodHint ); static InputMethodHint inputMethodHint( QWidget * ); void showMainWidget( QWidget*, bool nomax=FALSE ); void showMainDocumentWidget( QWidget*, bool nomax=FALSE ); static void showDialog( QDialog*, bool nomax=FALSE ); static int execDialog( QDialog*, bool nomax=FALSE ); + static int showWidget( QWidget*, bool nomax=FALSE ); /* Merge setTempScreenSaverMode */ #ifdef QTOPIA_INTERNAL_INITAPP void initApp( int argv, char **argv ); #endif static void setKeepRunning(); bool keepRunning() const; bool keyboardGrabbed() const; int exec(); signals: void clientMoused(); void timeChanged(); void clockChanged( bool pm ); void micChanged( bool muted ); void volumeChanged( bool muted ); void appMessage( const QCString& msg, const QByteArray& data); void weekChanged( bool startOnMonday ); void dateFormatChanged( DateFormat ); void flush(); void reload(); /* linkChanged signal */ private slots: void systemMessage( const QCString &msg, const QByteArray &data ); void pidMessage( const QCString &msg, const QByteArray &data ); void removeSenderFromStylusDict(); void hideOrQuit(); protected: bool qwsEventFilter( QWSEvent * ); void internalSetStyle( const QString &style ); void prepareForTermination(bool willrestart); virtual void restart(); virtual void shutdown(); bool eventFilter( QObject *, QEvent * ); void timerEvent( QTimerEvent * ); bool raiseAppropriateWindow(); virtual void tryQuit(); #if QT_VERSION > 233 virtual void polish ( QWidget * ); // this is actually implemented in qt_override.cpp (!) #endif private: #ifndef QT_NO_TRANSLATION void installTranslation( const QString& baseName ); #endif void mapToDefaultAction( QWSKeyEvent *ke, int defKey ); void processQCopFile(); #if defined(Q_WS_QWS) && !defined(QT_NO_COP) QCopChannel *sysChannel; QCopChannel *pidChannel; #endif QPEApplicationData *d; bool reserved_sh; }; inline void QPEApplication::showDialog( QDialog* d, bool nomax ) { QSize sh = d->sizeHint(); int w = QMAX(sh.width(),d->width()); int h = QMAX(sh.height(),d->height()); if ( !nomax && ( w > qApp->desktop()->width()*3/4 || h > qApp->desktop()->height()*3/4 ) ) { d->showMaximized(); } else { d->resize(w,h); d->show(); } } inline int QPEApplication::execDialog( QDialog* d, bool nomax ) { showDialog(d,nomax); return d->exec(); } +inline int QPEApplication::showWidget( QWidget* wg, bool nomax ) +{ + QSize sh = wg->sizeHint(); + int w = QMAX(sh.width(),wg->width()); + int h = QMAX(sh.height(),wg->height()); + if ( !nomax + && ( w > qApp->desktop()->width()*3/4 + || h > qApp->desktop()->height()*3/4 ) ) + { + wg->showMaximized(); + } else { + wg->resize(w,h); + wg->show(); + } +} + enum Transformation { Rot0, Rot90, Rot180, Rot270 }; /* from qgfxtransformed_qws.cpp */ inline int TransToDeg ( Transformation t ) { int d = static_cast<int>( t ); return d * 90; } inline Transformation DegToTrans ( int d ) { Transformation t = static_cast<Transformation>( d / 90 ); return t; } /* * Set current rotation of Opie, and rotation for newly started apps. * Differs from setDefaultRotation in that 1) it rotates currently running apps, * and 2) does not set deforient or save orientation to qpe.conf. */ inline void QPEApplication::setCurrentRotation( int r ) { // setTransformation has been introduced in Qt/Embedded 2.3.4 snapshots // for compatibility with the SharpROM use fallback to setDefaultTransformation() #if QT_VERSION > 233 Transformation e = DegToTrans( r ); ::setenv( "QWS_DISPLAY", QString( "Transformed:Rot%1:0" ).arg( r ).latin1(), 1 ); qApp->desktop()->qwsDisplay()->setTransformation( e ); #else setDefaultRotation( r ); #endif } #endif |
