What about "hideColumn()":http://doc.qt.nokia.com/latest/qtableview.html#hideColumn?

Do you want to write your own installer in Qt or you already have a Qt project which you want to install on different platforms? If the latter is the case then I can recommend you "InstallJammer":http://www.installjammer.com/ , which is free to distribute and use. I'm not sure if Mac support has been already implemented though. If you want to build your own installer then take a look at "Qt installer framework":https://qt.gitorious.org/qt-labs/installer-framework for some tips.

[quote author="Lukas Geyer" date="1310539567"]Probably "QMdiArea":http://doc.qt.nokia.com/latest/qmdiarea.html is what you are looking for.[/quote] Possibly, but I'm puzzled, so I couldn't ask it in simpler terms, LOL..

Sry ...i misunderstood...now i got it.. Thanks for your help..

Okay, I got it. Googled a bit to look for a way to add includes and libs onto Qt Creator. Didn't know you had to add them into the .pro file for each project =/ . Thanks for your help.

Using DLLs on non native platforms may work but the overhead is very considerable. Installing Qt on different platforms and recompilation takes a couple of mouseclicks. Distribution is very easy again. A couple of binary files go into one directory, thats it. Better think twice. "Your entering a world of pain" Walter Sobchack in "The Big Lebowski"

That time tests: @ QByteArray ba1(2048, 0); QByteArray ba2(2048, 255); QByteArray ba3(1024, 255); char *ba1data = ba1.data(); char *ba2data = ba2.data(); QElapsedTimer timer; timer.start(); for (int i = 0; i < 100000000; i++) { //ba2.replace(1000, 1024, ba1.data()+1000, 1024); // For 12324 ms. //ba2.replace(1000, 1024, ba1.mid(1000, 1024)); // For 33228 ms. //ba3 = ba1.left(1024); // For 45615 ms. <- ?! //ba3 = ba1.right(1024); // For 29640 ms. //ba3 = ba1.mid(1000, 1024); // For 29859 ms. //memcpy(ba2data+1000, ba1data+1000, 1024); // For 7722 ms. qMemCopy(ba2data+1000, ba1data+1000, 1024); // For 11981 ms. } qDebug() << timer.elapsed();@

Thanks Volker! That article is truly helpful!

Nice. Congrats. Please add [SOLVED] to your thread. Have a nice day.

actually I can do this by adding another animation on the rightWidget with "geometry" properties , but I think like QHBoxLayout , it should automatically resize when the size of one child widget changes .

[quote author="loladiro" date="1310421072"]Concerning 2). I am actually not sure that it can happen (i have heard people say it does, but never experienced it myself - probably because I don't use it that much). The only way I could imagine that happening is that the order is mixed up, because of the threading within QNetworkAcccessManager. And I always thinks it's better to be safe than sorry ;)[/quote] Fair enough, wish there was a little better explanation, but I fall in the same boat as you. Better safe then sorry :) and thank you for the information on that as well.

Thanks allot loladiro!

Hi All, I found the answer.... @ if(!highlightcursor.isNull()) { grepbrowser->append(highlightcursor.block().text()); } @ Hope this helps someone.

Thanx to all of you. I got the answer. Really very thanks. :)

Thanks!!!

It was easier that I thought. I wanted to filter data according to a foreign key. I had to fetch the PK of a table according to the value of the ComboBox. Here's how I did it: @ catModel->setFilter(""CAT_IndexGroupe" = " % QString::number( groupModel->data(groupModel->index(ui->MW_groupComboBox->currentIndex(), groupModel->fieldIndex("IndexGroupe")), Qt::DisplayRole).toInt()));@ Thanks everyone for your tips!
