You can get pointer to pushbutton in slot by using QObject::sender() method. If you have access to pushButtonList (I suppose it's QList) you can get button index with pushButtonList.indexOf(sender()). If you don't have access to pushButtonList from slot you should check QSignalMapper as mlong suggested.

Well, it looks pretty clear to me and when reading the documentation carefully with a clear C++ education not misleading at all. Still, feel free to make a suggestion to the bug tracker. Maybe they will update the documentation.

Problem in av_register_all(). "It's not declared in this scope" - it mean that you don't include file with defenition of av_register_all(). Maybe you should remove line #8 and #11 (in my wrapper).

I will give you an example. script.js @ function pF( number ) { return sqrt(number); } function pR( number ) { return number*number; } if( pR( pF(25) ) == 25) { print("I am Qt Script PRO!"); } @ mainwindow.cpp @ //... QString src = scriptFile.readAll(); QScriptValue a = engine.evaluate(src); if(a.isString()) qDebug() << a.toString(); //... @ It will print to debug log: "I am Qt Script PRO!".

Hmm, the endRemoveRows() does emit a signal to update the view. I would suggest looking into the View that you use if there is a "expand" level setting. The model looks correct to me.

QML + QtWebKit + HTML5 UI will be very tricky, and you will need to do C++ coding anyway if you need USB/Serial access. So, just use pure Qt C++, subclass QWebView & QWebPage and you can do then anything you want through bridging.

Yes, Windows provides very poor support for Posix.

Yes you can. In designer look at the sizePolicy property (expand it) and play around with Horizontal Policy and Vertical Policy. Make sure you have your tree and list widgets in a Vertical Layout.

I edit my makefile and the replace X11R6 with other value, the problem is fixed. basically, on my computer has no any X11R6. anyway, thanks everyone who posted here

thanks a lot for your post , the problem has been fixed after I add corresponding header files. [quote author="tucnak" date="1339585795"]Just make Debug build. Your build may be Release build.[/quote]

Done... Thanks for the reminder...

thanks for your help, with a search a see that generally there is a problem with centralwidget/mainwindow and background image

You may inherit and edit it.

Please reply!!!!

Hi mlong, I have verified that thread, but the solution provided is for qlistwidget, In my case i need to handle list of custom widgets for flicking

Bad luck, folks.... :( the only possible (found by now) solution is a dirty glue in lib source: @ bash-3.2$ pwd /Volumes/data/qt-everywhere-opensource-src-4.8.2/src/network/socket bash-3.2$ diff qnativesocketengine_unix.cpp.orig qnativesocketengine_unix.cpp 639a640,647 for(int i = 0 ; i < addressEntries.size() ; ++i) { if (addressEntries.at(i).ip().protocol() == QAbstractSocket::IPv4Protocol) { firstIP = addressEntries.at(i).ip(); break; } else continue; } bash-3.2$ @ sad... sad, story....

[quote author="miroslav" date="1339487318"]Note that if you are asking about properties, most experienced Qt developers will think if QObject properties, maybe even the dynamic kind (I certainly did). Those are a different kind of beast. In your case, the signal-slot mechanism is what you need.[/quote] Yes, in this moment this is all I need; but in the future....... ;-)

I found the (simple) problem! In NNTP protocol some lines (I read line by line now) begins with a double-dot, this must detect and replace with a single dot, that's it! All CRCs are conform now! Thanks to all for help anyway!

Another question... Can I make all UI in HTML5 and use C++ to communicate with USB/Serial?
