Besides needing to know what consitutes a row in your model, the items in your model also need to support some kind of interface that the model can use to query for the information it needs, like the string value or an icon or perhaps other relevant data.

I found that source. Thanks!

Oh good, I was about to reply now I got back from classes. Nice solution, thanks for sharing.

Additional information: calling the widget's visibleRegion() gives correct information - but where should I test it? I don't want to test with a timer, I would like to get an event about it or test it when a related event occurs. Is there any related event (occurs when the widget is moved into / moved out from the visible area)?

On the Mac you can just use the Qt::Drawer-style for Qt::WindowType. I think on other platforms, however, you will have to basically hand-code the whole thing.

In .pro file you have a variable TEMPLATE - default is app. You can try use a - "subdirs template":http://developer.qt.nokia.com/doc/qt-4.8/qmake-project-files.html#project-templates Check also "DEPENDPATH":http://developer.qt.nokia.com/doc/qt-4.8/qmake-variable-reference.html#dependpath - this can be done from Qt Creator interface. You can also think about change executable[1-5] from app to dynamic libs or plugins.

Ok thank you for the tip.

I found a solution but I do think its a bug. When I create the combobox, I immediately call setEditable(false), even though its the default (sometimes I set default values just for readability so I know they are set or whatnot, I never thought this would be an issue). I commented out this call and the problem went away. Seems weird that that made such a big difference but the problem was appearing repeatably every single time I'd pull the box down and then click away and as soon as I removed that line, it stopped happening. I meant to repost that as the "solution" but forgot.

If i remove /O2 then the Qt::DirectConnection do not work anymore. https://bugreports.qt.nokia.com/browse/QTBUG/fixforversion/11905 There seems to be a lot of broken things in VS2010 while 4.8.0 was introduced.

[quote author="Lukas Geyer" date="1326110211"]This is not how databases work. Data has been stored at the time a transaction has been committed. If it is not, there's something wrong with your code - which you may provide for further assistance.[/quote] ok i will check my code if no solution i found i will post here.

farooqmian as I had the same questioning and think a better answer than Volker did (whose answer I also disagreed in my thread by the way) I engage you to visit that "reference":http://vtun.sourceforge.net/tun/ where you can choose how far you want to go : tun or tap and. Then use it with SSL thanks to "this blog":http://xzis.me/2010/08/basic-samples-for-ssl-communication-using-qt/ where you'll have a concrete example. My understanding is that you want to learn by try process, so if this is true please let me know if you succeed or found something another tunneling solution.

@Volker thank you for response. Reason of this problem was not Qt-related. I somehow removed qsqlite plugin from my system. After reinstalling Qt everything works fine.

Ok thank u Andre..:) I'll consider your valuable suggestion...I'll go through that book....

Sorry for the misunderstanding. What I meant was a text that could be edited when editing the cell, that was the reason what I mentioned to use QLineEdit instead of QLabel. But what surely was very clear, was your advice. I got it working exactly as you suggested. Thanks again for your help.

If you have an proper *.pro file You can do : qmake -tp vc (see QMake manual "Creating Visual Studio Project Files") regards karl-heinz

[quote author="Volker" date="1326033677"] You see the characters "QStandardItem::data" literally somewhere in the few lines I've posted? No? So what makes you think that this can be the cause of an error message then? Do a search for "Tree" and replace it by "List" in your source code and you'll run into the very same troubles. BTW: Why are you using a QTree widget together with a QStandardItem?[/quote] your right volker. your code did not give the error message and I apologize. read what i said about that in my next post above. I am not replacing the code. i am starting over with a listwidget code that i got the signal and slot to work. everything is up and running now and without any problems. lately, i never really had too many problems declaring code up until the treeview code that was a bit too complicated for me. nevertheless, I am still studying c++ so bare with me until i get it all figured out.

Only by means of platform specific API, there's nothing built-in in Qt for that.
