opps, I never called QSqlTableModel::setTable(). Added an Q_ASSERT to the macro that gets the column id's so should have that problem again. Don't know why so many folks hate macro's, they sure speed up development when used correctly:) Ok, next issue. How do I get the primary key from this inserted row? In the beforeInsert() slot, the PK column is being set to not be generates so the SQLite's AUTOINCREMENT can do it thing: record.setGenerated(_orderModel->orderIdNo(), false); Here is the little catch, I know for an absolute FACT, in the very near feature the DB will be converted over to Firebird, which does NOT have a AUTOINCREMENT concept like most DB's. So ideally if there is a way to get the PK that will work today for SQLite and tomorrow for Firebird, that would be ideal! Sam

bq. If you then call a non-virtual method of a derived class through a base class pointer, the base class’ method is called (and not the derived one). all widgets which should be drawn have to be children of your QWidget-based class. As stated above, this is either done explicitly or implicitly – but never automatically. Ahh, I forgot about this. I suppose I need to be a bit more assertive with Qt's inheritance system... Then again, it's all about learning the library, and I'm a bit rusty in C++ atm. Thanks!

[quote author="Volker" date="1309441186"]Did you try adding a [[Doc:QAction]] with a shortcut and connect that to a slot?[/quote] This is the solution. Add two new buttons, connect them to slots and to the same as in find, only that you use the current cursor position as start position.

The solution for me is the following currently: Download Qt SDK 4.7.0 (4.7.1 - 4.7.3 not working): ftp://ftp.qt.nokia.com/qtsdk/qt-sdk-win-opensource-2010.05.exe (from ftp://ftp.qt.nokia.com/qtsdk) Statically build Qt according to instructions: http://doc.trolltech.com/4.7.1/deployment-windows.html#static-linking Statically build your apps according to the above instructions. I hope these will help you.

Thanks all for your help. I was unaware that repainting widget doesnt do anything to the data model. So i created a new slot loadTable() and moved the loading table data to the slot. So now i do @connect(guitimer, SIGNAL(timeout()), this, SLOT(loadTable())); @ Thanks a lot. It works fine.

If your opened window is a QDialog based widget, you can make it by @setModal(true)@ For QWidget based widget, try @setWindowModality ( Qt::WindowModality windowModality )@ And these 2 are all using/in the event loop

This works perfectly for me: @ QSettings testSettings; int sliderVal = testSettings.value("slider/value", 6).toInt(); qDebug() << "sliderVal=" << sliderVal; ui->horizontalSlider->setValue(sliderVal); @ Be sure NOT to call or trigger any slot connected to signal valueChanged() before you have set the default value.

Good to know :) don't forget to mark thread as [solved], please.

you're welcome bq. To bad this can’t be achieved with the designer Just a little bit of code to have the stylesheet all over your application, or changing it on ever dialog. I know what i prefer. ;)

Thanks allot for answering

I did not ask how to use UI, I just tried to understand the code generated by the UI designer to be able to find the solution to my problem. See my code up there is a class that inherits from QWidget and is displayed in a QMdiArea. @void WindowMain::evoqueSubWindClientes() { QWidget *subwincli = new MdiChildClientes(this); mdiarea->addSubWindow(subwincli); subwincli->resize(800,600); subwincli->show(); }@ But the command resize (800,600) does not have any effect.

Hi all, thanks for the help, this code helped me a lot. Does anybody know how to determine, if local IP comes from DHCP or is a static bind? Does anybody know how to assign new binding method (dhcp/static) and if static Does anybody know how to assign ip, mask and standard gateway. portable code is great, but I can be happy with Fedora code.... Thanks in advance.

Thanks, you're welcome. I've added a doc note to [[Doc:QDateTime]] for further reference.

Yes but why is that a problem for you? Constructing a formatted string is of very minimal cost when compared to actually getting it rendered on-screen. I think you are trying to optimise away a problem that doesn't exist.

Did you try use Qt::AlignAbsolute flag?

Οκ i will put a label.. No problem!

I think this has been solved. Not sure but I think a call to XSync was neccesary. THanks.
