if your use qmake, please run it again.

No problems ;) I've only put the decrypt() and encrypt() in a different thread ;) And i've connected "start" with "show", and "finished" with "close" :D Thank you anyway !

In any language except the 2 that i have already. When the second version is ready i will contact you soroush :) Any other language is welcome.

Thank you I ran out of scope of methods that was at least one query used in them and also deleted pointers to queries. now there is no warning :-) bq. An even simpler approach would be to simply ignore the warning. It won’t hurt you. I know, this is a homework => should look clear ;-)

Thank Tobias for the answer! No! The problem is specific :) I have my own (really safe, no files used) way to check if my application is running. I don't need this. I want your opinion about what would you have done in an occassion where your program was running in non-GUI mode and GUI was called, and briefly how would you do it (I have mentioned my way in the 1st post)

Try it, for example @QMenu{ background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #dddddd, stop: 1 #eeeeee); }@ It may interest you also http://qt-apps.org/content/show.php/Rizek+Qss+Editor?content=142455

I simply pointed out what was wrong with his code. At the time I used the QHttp (the code posted).. there was no other option. I think it is pretty clear to everybody and spelled out many times that it is deprecated now. Honestly, I found that out myself just recently over here. Anyways, I apologize for the confusion and yes.. the OP in the thread I linked would also be better off using the QNetworkManager classes currently. Thanks for adding that info to the thread. [ Edit: Have edited my "post":http://developer.qt.nokia.com/forums/viewreply/39453/ and added the code using the QNetworkManager. Once again sorry about that.. honest mistake..] [ Edit2: @kkrzewniak: Off-topic but its "deprecated" not "depreciated".. we all get it.. but just saying.. :-) ]

Thanks kkrzewniak, It was exactly what I was looking for. The problem is solved.

Thank you all for your suggestions. I solved my problem. I had already used dependency walker and installed all DLLs that it showed were required, and no DLLs were coming up missing when the application was launched. Process explorer was very helpful. I compared the loaded DLLs on a working and non-working machine, and found what I had done wrong. phonon_ds94.dll must be installed in a folder "phonon_backend" located under the application programs folder. I had put in in a folder called "phononbackend" by mistake. As soon as I corrected the name of that folder, my player started working. Process explorer showed that phonon_ds94.dll was not loading on the non-working machine. On the development machine it was loading phonon_ds94.dll from C:\Qt\2010.05\qt\plugins\phonon_backend.

Anyway ok i have done it one by one.. But is there any fade effect for a textedit? Because it returns me this when i do the opacity effect to a textedit: @QPainter::begin: A paint device can only be painted by one painter at a time. QPainter::translate: Painter not active QPainter::worldTransform: Painter not active QPainter::setWorldTransform: Painter not active QPainter::setWorldTransform: Painter not active@

You can use style sheets for custom coloring, but it will be no animation, just static colors and pictures.

Just to clarify, you could modify the text document with something like @ QTextCursor cursor = textEdit->textCursor(); cursor.insertText("blahblah"); @ without needing to call setTextCursor(). But the selection itself is a property of the text cursor and only on setTextCursor() is the visual cursor updated and hence the selection.

In that case time is not interesting. You might want to emit a progressChanged() signal containing a percentage. Stick to what you know. You know exactly how many calculations you are going to do, but you have no real clue about how much time it will take to complete them. If you use a percentage output, you can use a standard QProgressDialog and use that. It will by default pop up after 4 seconds of operation, but you can change that value if you wish, or show() immediately. People are usually better at guessing or estimating (guestimating) the time to finish based on tasks-completed progress than computers are.

You will need a special cross compiler for that, a normal mingw will not work: Apple uses a binary format that differs from the one used on windows. The macx-xcode spec expects the mac compiler set up as on a mac, too, so that is unlikely to work with a cross-compiler tool chain on windows. I saw a documentation on how to "cross-compile from Linux to Mac":http://devs.openttd.org/~truebrain/compile-farm/apple-darwin9.txt before, maybe that can be used as some form of inspiration for a similar setup on Windows... Note that the process seems to depend heavily on which version of MacOS you want to target.

Thanks for the clarification about the shell etc. I connected a slot to the QProcess::error() signal and it's working great.

From what ive tried which isn't much the QtCreators Mercurial integration only seems to work for local repositories. I tried integrating it into a wider repo and had issues then decided to manage the repo manually from the command line. If anyone has tips for integrating it better it would be much appreciated. One of my main problems is i have multiple projects that use shared libs all in the 1 repository.

That's just what I was after, thanks!

Yeah, the reason why I'm asking for advice is for faster performance, cleaner syntax, etc. Andre, I suppose why I inherited from QSplitter is because, at first impression, I had intended it to be a splitter varient. But now that I think of it again it's really just an object of its own, and I agree that not all of the inherited functions will work anyway. Most would probably have to be reimplemented. For now I'll just inherit QuadSplit from QObject, I might narrow it down to its true "family line" if I want to venture into that, but I'm not sure if it's necessary. But maybe it is. After all I've barely looked through all of the member functions for these classes as of yet. bq. There are better ways of implementing your QuadSplit than using three QSplitters that need to be kept in sync. What do you have in mind? I could definatly use advice on how to improve it, whether performance or syntax wise.
