General and Desktop

i guess you already have a project with a .pro file, headers and sources and you want to add an additional dialog with associated header and source file? ok in this case what you can do is the following : file > new file or project > on the left under files and classes select "Qt", then you can choose on the right for "Qt designer form class". this will generate ui, h and cpp files for you and will add everything in your pro file.

Hi, QSettings is used indirectly in the examples of Qt docs, e.g. in "Main Window examples":http://doc.qt.nokia.com/4.7/mainwindows-application.html for storing application settings: [quote] @ void MainWindow::readSettings() { QSettings settings("Trolltech", "Application Example"); QPoint pos = settings.value("pos", QPoint(200, 200)).toPoint(); QSize size = settings.value("size", QSize(400, 400)).toSize(); resize(size); move(pos); } void MainWindow::writeSettings() { QSettings settings("Trolltech", "Application Example"); settings.setValue("pos", pos()); settings.setValue("size", size()); } @ [/quote]

LIBS += -L../../bin/ -lMyLibrary

And don't forget to set quitOnLastWindowClosed as false.

Looks like it's my fault, so Qt is the best.

No, it is not supported to be output the way you suggested.

Trying another approach to the same problem, is no reason to start a new topic. Indeed, I did suggest that you don't use the Q3 support classes in new code, and I stand by that. You were also "suggested":http://developer.qt.nokia.com/forums/viewthread/6242/ to take a look at using a QFileSystemModel with the CheckableProxyModel class. You did not even respond to that route. Is there any reason you can not use that method? What is wrong with it? If you want to immediately respond to changes to the check state of your model's items, you will need to either modify (subclass) your model, or insert a proxy model. Either way, you can add a signal checkStateChanged(QModelIndex index, Qt::CheckState state) that you can emit from the setData() method of the model or proxy if that role is being changed. Of course, that would only work for when that is done from the view (or at least, through the setData interface of the model), but that would probably be enough for you. You'll need to emit that signal when the CheckStateRole is set. Note that the CheckableProxyModel mentioned earlier just gives you a signal checkedNodesChanged() that tells you something happened.

Feel free to open a new bug or reopen an existing one:-)

i thought that i had done that, but clearly not

Thanks LiamMaru, I have already try to use the same OpenGL context in different thread, but I have forgotten to call : QGlContext::doneCurrent() in the main GUI thread and I had some crash. I will try it as soon as possible. But, when using the same OpenGL context in another thread, it will not be possible to refresh the view of the main GUI thread... So it will freeze the application ! No issue ?

[quote author="Naouali" date="1306334812"]Hi how can i convert a QDateTime to Mysql datetime ? thanks in advance[/quote] Same way as you do it the other way around: simply rely on the Qt Sql drivers framework to do that for you. I merged this question with the one you asked about doing it the other way around.

I didn't know about "Global Declarations" and I've never heard about Global Declarations . Now I think I understand the warning. Thanks.

If I use @void QGraphicsItemGroup::addToGroup ( QGraphicsItem * item )@ will the RubberBand intersection be tested only against the group or will it still be tested against every member of the group?

the problem was solved , i have two installation of Qt , i used the one installed from repository (ubuntu ) and it works fine . thanks for your help .

OK, great. Glad that you got it working ok.

Thank you, that was exactly what I was looking for!

That works perfectly. Thanks

The Qt4 QListView is a one dimensional MVC-Container. Therefore you need a model, which reacts on the role Qt::CheckStateRole in its data method.
