You need to add the path to the dylib files to DYLD_LIBRARAY_PATH for the executabel to find them. Maybe the macdeployqt tool could be of help too.

Ah that explains it. Thank you guys.

Ah, so you just want to compile your application (made with QtCreator) for 64 bit? Just download the 64-Bit version of Qt from their download page and compile on a 64-bit system: http://qt.nokia.com/downloads/sdk-linux-x11-64bit-cpp

you guys are right, changing to vector is working very well,thanks

I'm not quite sure about your requirements, but QWidget (more specifically QObject) has a sender() method, which allows for retrieving the emitting object within a slot. @ void doWidgetClick() { CustomWidget pSender = qobject_cast<CustomWidget>(sender()); } @ For the "correct" solution design-wise you should consider using a "QSignalMapper":http://qt-project.org/doc/qt-4.8/qsignalmapper.html. As to your code: You cannot pass values using the connect() statement. @ // WRONG, this is a value, not a type connect(this, SIGNAL(click()), pReceiver, SLOT(doWidgetClick(this))); idget*))); @ Slots can only have less, not more arguments (excluding signal default arguments). @ // WRONG, slot has more arguments than signal // RIGHT, only if click signal has at least one default argument connect(this, SIGNAL(click()), pReceiver, SLOT(doWidgetClick(QWidget*))); @

Actually, I am refering to the Qt Creator and its option to set a WLAN adress instead of a COM Port to transfer the data to which works with CODA (Debug Agent) that has to be started. If you are interested, search for the text string WLAN "here":http://doc.qt.nokia.com/qtcreator-2.4/creator-running-targets.html#running-on-a-device. And I hope that someone could explain this thing to me :)

In both cases I close the dialog. But only the one using QDialog::show() will NOT block at QApplication::exec(). I read somewhere that this happens because my QDialog has no parent widget assigned. [quote author="1+1=2" date="1335891728"]If your @ myDialog @ is your only Widget. When it's closed, your application will be marked as finished. so QApplication::exec() will exit ASAP. [/quote] The reason I use exec() and not show() or open() is because the call is inside a loop like this: @ bool keepLooping = true; do { QDialog myDialog int result = myDialog.exec(); if(result) { if(something) keepLooping = false; } else { keepLooping = false; } } while(keepLooping); myQApplication.exec(); // The application exits now @ This will only work with QDialog::exec(). I guess the QApplication::exec() at the end of the code above is reduntant at this particular case because the application is going to quit anyway. To be honset I do not know why it is there at first place (it is a big project I am not the one who wrote this code). An alternative solution would be to add: @ QTimer::singleShot(0, &myQApplication, SLOT(quit())); @ ..before calling QApplication::exec(); Thanks a lot for your help guys! Cheers, Bekos

Or may be try clean and build or rebuild.

Somebody know, why if columns IDStanowiska or DataUrodzenia is emplt (have Value NULL) then cant delete this row ?? Columns Imie and Nazwisko can by emplty, because they are NOT NULL and MySQL automatically add empty String . Somebody Know how delete row if in View exist column how have NULL value ??

I found "address book example":http://doc.qt.nokia.com/4.7-snapshot/itemviews-addressbook.html and after going through the code i came to know that i need to subclass QAbstractTableModel and override the required functions. But still find this a long way to go as i need to store a single object for each/particular row. Thanks for your time :)

Do you know where qmake is installed? If you know the path, may be try adding the path of qmake and see whether it is working?

Hmmm, not all my threads are QThreads... I'm guessing QThreadStorage wouldn't work right for me? In fact, only the UI stuff runs in QThreads in my project, I think.

Would like to use the auto connection, but without the connect, the slot doesn't get called. Other auto connection slots on other dialogs work fine. Is there something else to do to get auto connect to work with the QItemSelectionModel?

To trigger your paint event just call update() on your custom widget.

You mean it could be an issue of the firewall?? Wow, I would have never thought about it. I'll give it a try.

Thanks. It works
