Ok then, thanks again!

@koahnig Thanks...

Use a QAbstractItemView sub class. QScrollArea dose not work with items it works with widgets. Consider reading a book "C++ GUI Programming with Qt-4 1st edition.":http://www.qtrac.eu/C++-GUI-Programming-with-Qt-4-1st-ed.zip Reading a C++ book wouldn't hurt too, ass you are having problems understating simple compiler output. Or at least use assistant.

Thanks a lot. Second one looks good. I'll try. :)

thanks Vijay and sigrid , currently my solution is to implement a widget inheriting from QGraphicsProxyWidget , and export it to QML with qmlRegiesterType

[quote author="Volker" date="1304607729"]@ ... qDebug() << qApp->libraryPaths(); ...@ Is the mysql plugin listed in a subdir "sqldrivers" in one of the paths printed?[/quote] Thanks for those accurate advices Volker, I was wondering why the driver wasn't found when I past the .so next to my executable. I was missing to put it in a subfolder named sqldrivers !

Use the (updated) code from here https://qt.gitorious.org/qt-labs/modelviewer .

Yep, it's tough to come out of game lingo. Sorry for the confusion. QTimer method worked for me though. Thanks!

finally, I did not need the synchronisation toolkit like in swing. The low FPS was caused by the fact that I had been launching the application under IDE on slower PC. Now it works great:) And I understand I will write posts there. Thank you :)

[quote author="Vass" date="1309298312"]May be it will be interesting for you: "Image Gestures Example":http://doc.qt.nokia.com/4.7/gestures-imagegestures.html[/quote] That actually seems like a good idea. Unfortunately, I can't seem to get a QSwipeGesture to work in a QGraphicsView. Here's what I have so far: Class Declaration: @class sliceView : public QGraphicsView { Q_OBJECT public: explicit sliceView(QWidget *parent = 0); bool viewportEvent(QEvent *event); signals: void moveToMainViewer(QEvent *); void goBack(QSwipeGesture *); void goForward(QEvent *); void changeLevel(QEvent *); protected: bool event(QEvent *event); private: bool gestureEvent(QGestureEvent *event); void swipeTriggered(QSwipeGesture *); };@ .cpp file: @ #include "sliceview.h" #include <QtGui> #include <QTouchEvent> sliceView::sliceView(QWidget *parent) : QGraphicsView(parent) { viewport()->setAttribute(Qt::WA_AcceptTouchEvents); grabGesture(Qt::SwipeGesture); } bool sliceView::event(QEvent event) { if(event->type() == QEvent::Gesture) return gestureEvent(static_cast<QGestureEvent>(event)); return QGraphicsView::event(event); } bool sliceView::gestureEvent(QGestureEvent *event) { if(QGesture *swipe = event->gesture(Qt::SwipeGesture)) swipeTriggered(static_cast<QSwipeGesture *> (swipe)); return true; } void sliceView::swipeTriggered(QSwipeGesture *gesture) { if(gesture->state() == Qt::GestureFinished) { if(gesture->horizontalDirection() == QSwipeGesture::Left) emit goBack(gesture); update(); } } bool sliceView::viewportEvent(QEvent *event) { switch(event->type()) { case QEvent::TouchBegin: case QEvent::TouchUpdate: case QEvent::TouchEnd: { QTouchEvent *touchEvent = static_cast<QTouchEvent *>(event); QListQTouchEvent::TouchPoint touchPoints = touchEvent->touchPoints(); if(touchPoints.count() == 3) { if(touchEvent->touchPointStates() & Qt::TouchPointPressed) { emit changeLevel(event); } } else if(touchPoints.count() == 4) { if(touchEvent->touchPointStates() & Qt::TouchPointReleased) { emit moveToMainViewer(event); } } return true; } default: break; } return QGraphicsView::viewportEvent(event); } @

I know, i added line 2 manually to make sure what cbDsn is...just corrected this.

Yes I'm aware of your view that one should not connect foreign signals to private slots, but you have not mentioned it in your original post concerning making the slot public. This may lead to a false assumptions that such connections are impossible.

The following "FAQ":http://developer.qt.nokia.com/faq/answer/is_it_possible_to_move_the_qt_directory_to_another_directory_after_installa contains information on what you need to do when moving your Qt installation around.

See "format property":http://doc.qt.nokia.com/4.7/qprogressbar.html#format-prop you can add your text to this property and it will be show on progress bar

Many thanks for help!

[quote author="Andre" date="1309338341"]@Rajveer: QReadWriteLock does not work across processes, so it is useless for this case. [/quote] Thanks for the hint. I hadn't stumbled upon "QSystemSemaphore's":http://developer.qt.nokia.com/doc/qt-4.7/qsystemsemaphore.html up until now. Thanks for that hint too.

thats same problem with me, solved mine either.. thanks

Sorry it was smart installer. my mistake "Your text to link here...":https://picasaweb.google.com/lh/photo/8IdRKlR4hIEYObwGDdcZoQ?feat=directlink
