Hi, Thanks for the reply. I will try in that case to make it with some temporary containers and playing with the load/unload of the languages... I'l keep update the thread if I have a good solution. Best regards, Nouch.

Of which type is milliSec?

thanks. (I thought ever QGraphicsSceneXXXX stuff is included in the QGraphicsScene header.)

SOLVED: The reason the editor widget was loosing focus was because the QMenu object that was being created during the contextMenuEvent was not being constructed with a parent object defined. @c_menu = QtGui.QMenu(self)@ This ensures the editor widget maintains focus when the context menu is created.

Finally ! Thanks Andre

Yep: @style()->unpolish(theWidget); style()->polish(theWidget);@ Did the job. Thanks! (Although, as having polish ancestry, I object to the wording of the API ;-) )

[quote author="AcerExtensa" date="1327937473"]@file.open(QIODevice::Append)@ is the same as @fopen("fnmae","ab")@[/quote] Thank you !

bah soz abt the post. solved it myself (most of) @ QGraphicsOpacityEffect* fade_effect = new QGraphicsOpacityEffect(this); this->setGraphicsEffect(fade_effect); QPropertyAnimation *animation = new QPropertyAnimation(fade_effect, "opacity"); animation->setEasingCurve(QEasingCurve::InOutQuad); animation->setDuration(500); animation->setStartValue(0.01); animation->setEndValue(1.0); animation->start(QPropertyAnimation::DeleteWhenStopped); this->setVisible(true); @ Just the last 2 lines im not toally sure about yet if its ok to use like that. Just dont want to end up with a nasty flicker on some less powerful machine because of it.

Thank you very much! But what about the code inside of .zip? Could you, please, comment it? I mean, mainwindow.cpp and other guys, excluding first.cpp and first.h.

Yes I Used QSFPM and It worked just fine Thanks

If you need the win API for versioninfo, have a look "at this thread":http://developer.qt.nokia.com/forums/viewthread/11377/

Sorry, I have absolutely no knowledge about tclsh and how it behaves. I can only give general advice here, and usually problems caused by "missing" stdout from a QProcess is caused by some buffering on the started process' side...

Hi Yes, if you look at the code you will see that I have tried that. What I dont understand is a way to make writeDatagram behave like socket.h function sendto in blocking mode. Any help would be appreciated Regards

Singletons probably won't hit you immediately (except you are doing unit testing or multithreaded programming), but as with every bad design choice they involve a potential problem that might hit you at any time - with an increasing probability the lager a project becomes. And a global state, tight coupling and the violation of the single responsibility rule are huge problems when they become a problem. There are situations where singletons do make sense, but in 90% of cases singletons are just misused and they are used as a substitution for a global variable - and in the remaining 10% the classical singleton pattern can be most probably substituted with another singleton-like design pattern. In my humble opinion this fact alone qualifies them as an anti pattern. But enough of derailing this topic! :) Let's end it with a riddle: who said "When discussing which patterns to drop, we found that we still love them all. (Not really—I'm in favor of dropping Singleton. Its use is almost always a design smell.)"?

Thank you for pointing me in the correct direction, once I know the solution was found within the editorEvent(), I found this article that solves both my problem along with centering the checkbox. Very nice! "How can I align the checkboxes in a view?":http://developer.qt.nokia.com/faq/answer/how_can_i_align_the_checkboxes_in_a_view

For the types mentioned in the title (odt = Open Office, doc/docx = MS Word), there is nothing built into Qt. You will have to use external libraries that parse that file formats for you (or write them yourself).

For those who want to solve the same problem, I have written a Wiki page with the code snippet "link":https://developer.qt.nokia.com/wiki/QSortFilterProxyModel_subclass_for_text_alignment_-and_readonly_columns. Thanks again Andre for the solution proposal. I hope the code I have written can evolve to some more complete class which can satisfy every user. Feel free to edit this Wiki page!

I seem to have fixed this now - I was getting (and ignoring as I didn't think it was relevant and the code ran) the compile error: /usr/lib64/gcc/x86_64-suse-linux/4.5/../../../../x86_64-suse-linux/bin/ld: skipping incompatible /usr/X11R6/lib/libGL.so when searching for -lGL My project '.pro' file was missing '-L/usr/X11R6/lib64' in the 'LIBS =' line. When you create the Makefile (e.g. via 'Run qmake' in Qt-Creator) it creates a makefile with this library call in. You have to remove the existing '-L/usr/X11R6/lib' entry for the 32-bit libraries. It then appears to compile okay. It no longer produces the error mentioned above and the shaders compile. Apologies for the convoluted method - it would be better to change the default libraries used. I guess this is done via a different qmake '.conf' file, but I've not worked out how to find / change this via Qt Creator yet...

Just making an modest observation for further improvement, as advised by Nokia itself... In fact, there wouldn't be so much to change. Right now there is already a beautiful mechanism, the stylesheet, that makes it possible to style some properties of a treeview, like the background color for example. So one possibility would be to extend these properties (with something like CSS selectors, allowing to select specific row and/or columns, and even items). For example I don't understand why it's not possible to set the text-align of a qtreeview via the stylesheet, while it is with some other widgets ? (or maybe it is, but I failed to find how). Otherwise I finally got the right way to "flash" a specific item, indeed subclassing itemdelegate, so if anyone is interested, just ask....
