Your table view is created on the stack. As soon as the variable goes out of scpe - here: your constructor has finished - it is destroyed. Use a pointer and heap allocation: @ QTableView *tableView = new QTableView(this); tableView->setModel(model); @ Also, make sure to make the view the central widget or add it to a layout.

this is a pointer to the object you are in - in this case it's the Notepad object. aApp is a convenience macro that returns a pointer to the QApplication object. The recent docs with the "Getting started with Qt tutorial":/doc/qt-4.8/gettingstartedqt.html have some additions regarding the missing methods.

No one to answer? Same question here...

That signal is emitted continuously. Do you use some proxy/firewall/viruswall - maybe a hidden one? In that case it could be that the proxy waits until the download is finished, checks the contents an delivers it to your application.

I would open a bug report against qmake here.

QProcess::execute() is a static method. It does not return any output of the started command/executable. You will have to use the non-static methods in order to ready any data. @ QProcess p; p.start("/etc/rc.d/S09pppd status"); p.waitForFinished(); // blocks! QByteArray output = p.readAllStandardOutput(); @

I see that Qt SDK 1.2.2 still isn't out. Thought it would be just about to be released. Can't find any updates. Is there any release schedule?

@ #include "fcntl.h" QFile f(path); if(f.open(QIODevice::ReadOnly)) { fcntl(f.handle(),F_GLOBAL_NOCACHE,1); } @ Seems to do it!

Or you can look at the code in QWT, and then write something like it yourself.

Sorry, can't help you. compile your plugins both debug and release, add to .pro file, @ qt += sql @ compile your Qt application with same compiler as you just compiled libraries, put your plugin libraries in right place, copy any other libraries provided by DBMS vendor beside your application. This works properly for me.

this is something what i want to achieve http://dl.dropbox.com/u/35031827/cute d.png

I had reading somewhere that moveToThread(this) was not more necessary since Qt 4.7. Thank you both. I will go deeply in the docs you had provided. ty again

I thought that, my proposed ideas included a QTableView but I was shown a demo with it using a grid layout but I cannot repeat it, must have been smoke and mirrors - hard to question a task when it has been demonstrated to work, but I have no idea what he did, I'll get him when he is back in the office :-S So why does it allow me to add columns then, it the only the view accepting colums? HA HA!!! setFlow(QListView::LeftToRight); Yes!!

Another important read on the correct use of QThreads is "this one":http://qt-project.org/wiki/QThreads_general_usage. Its not as extensive as the one suggested by Lukas Geyer but instead focuses on the (in my opinion) most important aspect related to the use of QThreads, namely the fact that they themself are not a thread but a wrapper around a thread object. And thus should be used this way.

Another good read on threads and the recommended approach for using QThreads is "this one":http://qt-project.org/wiki/QThreads_general_usage.
