General and Desktop

Thank you all, sudo qtconfig did the trick!

Clearly I'm not using itemselectionchanged. I posted that comment to point out that I've already tried numerous signals on the QTreeView including the selectionChanged signal that you suggested. None of them worked. My goal was to find an alternative signal to itemSelectionChanged that was also similar in its behavior. I was finally able to detect selection changes on the tree view by using the selection model as suggested by Andre (tree->selectionModel()) and the QItemSelectionModel's selectionChanged() signal. It seems to work as expected. Thanks for the suggestions.

Thanks for the advise Marco! You are a real help! Im sorry i can not be of any help for your problem. regards, vinb

You can place it anywhere you want like any other widget. You won't have the tool bar areas that a QMainWindow has, though. QWidget has: @ void setFixedHeight ( int h ) void setFixedSize ( const QSize & s ) void setFixedSize ( int w, int h ) void setFixedWidth ( int w ) void setMaximumHeight ( int maxh ) void setMaximumSize ( const QSize & ) void setMaximumSize ( int maxw, int maxh ) void setMaximumWidth ( int maxw ) void setMinimumHeight ( int minh ) void setMinimumSize ( const QSize & ) void setMinimumSize ( int minw, int minh ) void setMinimumWidth ( int minw )@ QSplashScreen

Hi Marco, I have no solution for your problem, but i have a similair problem wich is discussed in "this":http://developer.qt.nokia.com/forums/viewthread/5203 topic. Can you also have a look there and help me out a little? Kind regards, vinb.

@Andre, thanks for those words. :) But i know for sure, that your knowledge of Qt is much greater then mine.

If the connect fails, what is the output of the sockets error() [doc.qt.nokia.com] method? QAbstractSocket::ProxyConnectionClosedError "Proxy connection closed prematurely"

So any ideas on how to get the proper row highlighted AFTER the table is sorted? I have not had any luck with my attempts.

Q_OBJECT works only for QObject derived classes. This makes QObject the toplevel class in the inheritance hierarchy. As Q_GADGET enables a subset of the meta object system on classes not based on QObject and moc is run anayways, I suspect this holds for those classes too: moc just expects that the base classes are gadgets too. Adding the Q_GADGET macro to class A should have no impact on your existing software, as it just adds some extra stuff and does not change your existing code. The only drawback might be a binary incompatibility, due to the fact that the class interface changes.

Easy enough, just try to compile that @ #include <QWidget> #include <QApplication> #include <QSizePolicy> class MyWidget:public QWidget { public: MyWidget():QWidget(){}; ~MyWidget(){}; virtual int heightForWidth ( int w ) const { return w*9/16;}; }; int main (int argv, char** argc) { QApplication a(argv,argc); MyWidget w; QSizePolicy qsp(QSizePolicy::Preferred,QSizePolicy::Preferred); qsp.setHeightForWidth(true); w.setSizePolicy(qsp); w.show(); a.exec(&#41;; } @ and resize the windows : it doesn't care about aspect ratio at all...

They are both valid solutions. In fact they amount to the same thing since that is all that the setFixedSize() function does anyway.

you can download the source from xamp file ;)

It looks to be because your local clone was made from your own personal clone on gitorious not from the actual Qt repo. If you have not updated your personal clone on gitorious since you last pulled then of course there will be nothing to fetch. What you have done by editing that file in this way is to tell git that you really did clone it from the official Qt repo on gitorious. I usually just get my local repo by cloning the official Qt repo on gitorious and then explicitly tell git to push to my personal clone (or a team clone) on gitorious when I wish to publish my changes. The reason for this is that I do not see that gitorious provides any interface for directly pullling changes from the official Qt repo to a personal/team clone on gitorious. So my data flow is: @ Official Qt repo --> Local Qt clone ---> make local changes in branch --> Push to personal clone on gitorious --> Prepare Merge Request @ What you appear to be trying to do is: @ Official Qt repo --> Personal clone on gitorious --> local clone --> make changes in branch --> Push to personal clone on gitorious --> Prepare Merge Request @ The problem is that the "pull" represented by the first arrow only happens once when you make the initial clone.

[quote author="Smar" date="1303137713"]In theory, qDebug() takes some buffer and does something for it that would otherwise make the faulty line address memory that is not usually available.[/quote] This explanation is sufficient for me, thank you :) [quote author="Smar" date="1303137713"] Valgrind would tell exact reason for that, just use it, since you’re only one who actually has your code.

You can have a look at "This article on stack overflow":http://stackoverflow.com/questions/5675884/easy-way-to-cross-compile-a-qt-application-using-qt-creator/5676089#5676089 Basically, I don't know if mingwin gcc allows you to cross-compile (never heard of that and I use visual here, I can't really mess with my environment to try), but the easiest is definitely to have a linux VM running, synchronized with your SCM: this way, you know what / when you build fairly easily

ok. The problem was solved. I just used QNetworkProxy, and a bit code for support at mine proxy.
