I'm making the transition from Eclipse CDT (with Qt integration plugin) to QtCreator 2.0 but there is still one thing that bother me with QtCreator : When I debug in QtCreator, I don't see my qDebug messages inside the Application output tab until I stop the application I'm debugging... Then they are all displayed at once which is not v...

I have some code creating a QTabWidget from Python using PyQt4. I want to get a 'throbber' animated gif in the tab. The /only way/ I have found how to do this is the following convoluted method. tabBar = self.tabReports.tabBar() lbl = QtGui.QLabel(self.tabReports) movie = QtGui.QMovie(os.path.join(self.basedir, "images\\throbber.gif")) ...
I have QGraphicsTextItem objects on a QGraphicsScene. The user can scale the QGraphicsTextItem objects by dragging the corners. (I am using a custom "transformation editor" to do this.) The user can also change the size of the QGraphicsTextItem by changing the font size from a property panel. What I would like to do is unify these so tha...
I really wanna do cross platform applications. I have great experience in .NET, so the only option is Silverlight. But it's not as powerful as WPF (yet). Is it possible to use WPF's controls like Menu & ToolBar? Is it possible to make real installers for Silverlight apps? (Not just out of browser install.) Is it really worth it, or s...
I recently refactored old code files from ABCFile.cpp/.h to AbcFile.cpp/.h to match my company's coding standards. After updating all the references to the old case styling, the code is compiling and running just fine, but looking at qt's automatically generated moc files the casing matches the old style. What do I need to update qt's ...
I need to import file sequences into a Qt program. Import itself is not hard, but I'm pondering what might be the most easiest way to detect if the files form a sequence, e.g.: filename_00001.png filename_00002.png filename_00003.png etc. Now, I have a drag'n'drop import working, and I'm sorting the list of imported files alphabetical...
The documentation for QStringList QCoreApplication::arguments() (Qt) states that: Usually arguments().at(0) is the program name, arguments().at(1) is the first argument, and arguments().last() is the last argument. See the note below about Windows. It further elaborates: On Windows, [...] the arguments() are construct...
Assume that a program is run several times in identical fashion. In each run, the same set of objects is insert into a QHash in the same insertion order; then the objects in the QHash are iterated. The question is will the objects be iterated in the same order in each run of the program? ...

Indeed I want to have this kind of color distribution to...

Just trying to mess around with Qt and SQLite to get familiar with how things work- I haven't really done DB programming since my vb6 days, so please be easy ;] I'm just trying to get the result of a query and I'm trying to follow some examples I found online (namely this one). The process seems simple enough: create the QSqlQuery objec...
Disclaimer: I know there aren't any lawyers here, but I'd like to hear some opinions. I'm making a Python application using PyQt4 for the GUI. It will be open source, maybe GPL, but rather MIT/BSD licence since I don't see the value of copyleft for it. Since I cannot rely on users to have PyQt installed (in fact, I'm safe to assume that...
