I construct a QDateTime from a string like this: QDateTime date = QDateTime::fromString("2010-10-25T10:28:58.570Z", "yyyy-MM-ddTHH:mm:ss.zzzZ"); I know that date is in UTC because that is the way it's stored. But when I want to display this date to the user, it should be in the user's local time zone. date.toLocalTime() looks promisin...
Hi all, I have a table with 3000 rows and 8 columns. I use the QTableView. To insert items I do: QStandardItem* vSItem = new QStandardItem(); vSItem->setText("Blabla"); mModel->setItem(row, column, vSItem); where mModel is QStandardItemModel. Everything is fine if I have not to many rows, but when I am trying to visualize big data (...

I'm just learning PyQt and looking at the Signals and Slots mechanism. I'm a bit baffled by the verbose syntax. Why do we have: self.connect(dial, SIGNAL("valueChanged(int)"), spinbox.setValue) I would much prefer to write the following: self.connect(dial.valueChanged, spinbox.setValue) Can anyone tell me why the connect() syntax n...

Hello! I'm programming a QGraphicsView that has a lot of images. But when I display a JPEG with resolution 8528 x 1128 px (a panorama image), the QGraphicsPixmapItem does not render. It just displays a black square. Images of "normal" size renders good. I have not tried to find the "magick limit" for what sizes the problem occures on. ...

Hi, I am to Qt Creator. I have one of the latest versions. I have two really newby quesions. is there something like VS solution? In which you can add projects and set project dependencies and build order? if I have multiple open projects, how do I set one of them as "default", so that Ctrl+B builds specifically that project? ...
In Qt, there is a nice idiom to have each object associated with a thread, so that all its event handlers will only run in that thread (unless called directly, of course). Is there anything even remotely like that in C#/.NET? If not, how would you start writing your own? Example: // threaded.h #include <QThread> #include <QDebug> #in...

It doesn't need to be running in an external app, if there is a widget that can display this information. So the question is, does such a mythical beast exist? ...

I'm trying to convert a QVariantMap to Qt Script object. If I understood correctly it should go something like this: QScriptEngine* engine = new QScriptEngine(); QVariantMap* test = new QVariantMap(); test.insert("testkey", QString("testvalue")); QScriptValue testqs = engine->toScriptValue(test); QString value = testqs.property("testkey...
I am converting a large application to compile with lsbc++. I do not aim for full LSB compliance, I just want it to work with all but one of the LSB4.0 distributions (the remaining distribution is RHEL3 and lacks 100s of interfaces I use). The current situation is that I am missing one symbol in one library (of about 40 libraries/executa...
We've implemented a subclass of QTextBrowser to act as a local cache. We've overriden loadResource to provide all the resources requested. This works well as long as the resource is properly formatted. However, if there is some problem with the resource then Qt will try to load the resource itself. We'd like to disable that functiona...
