Hi, I'm trying to use SVG graphics in QIcons. I have a static library that contains all my graphics resources, and a method in that static library that returns QIcons pre-loaded with the correct graphics. I'm trying to do this: QIcon icon(":/icons/find.svg"); I have verified that that resources has been loaded by listing it with QDir...
Hi folks, How I can acquire access to QTabBar of QTabWidget ? Through searching in docs and internet, I've found only solution: subclassing QTabWidget, and in some way giving public access to QTabBar instance (QTabWidget::getTabBar() has "protected" access modifier). Is there any other solution ? ...
I designed a QMainWindow with QtCreator's designer. It consists of the default central widget (a QWidget) which contains a QVBoxLayout with all the other widgets in it. Now everything I want, is that the QVBoxLayout automatically occupies the whole central widgets rectangle space. How can I do this? I didn't find any usable property nei...

I was trying to perform basic authentication for Twitter from my Qt app. I use QNetworkAccessManager. But I couldn't find any help on this. But I found a program called qsoapmanager which passes credentials in base64 through the header. Maybe I can do this with QNAM by setting header in QNetowrkRequest. But I failed to find a way. In q...

I realize that there have been similar questions, but they seem to have been from when Qt Creator was still in beta, so the answer might have changed since then: We are going to start a project with a small amount of GUI that needs to work on Windows, OS X and Linux. So choosing Qt was a no-brainer, even though we have little experience...
Hi, I want to use the VC++ toolset to build programs for XP and Vista, but I do not want to buy the IDE, because I want to use Qt Creator. I would download the Windows SDK and the Windows Debugging Tools, but I'm not sure if this includes everything that I need (i.e: compiler, linker, nmake, debuggers). Has anyone used this approach? H...

In a Qt4 application, is it possible to tell inside a paintEvent() handler whether the repaint was triggered by a resize or not? I have a widget which is very slow to redraw (a complicated plot), and I want to speed up resizes by just blitting a resized pixmap while the widget is being resized, and only redraw the widget when the resiz...

What is the process behind making custom widgets (using Qt) that don't look...well...ugly? I know it is fairly trivial to make a "custom widget" that has say, a listbox and a pushbutton slapped together into one, but how would I go about making something that looks more like this: QAnalogWidgets I have made some rough mock-ups that ba...
Hi guys, I'm adding a contextmenu to a QTableWidget dynamically: playlistContenxt = QAction("Add to %s" % (currentItem.text()), self.musicTable) playlistContenxt.setData(currentData) self.connect(playlistContenxt, SIGNAL("triggered()"), self.addToPlaylistAction) self.musicTable.addAction(playlistContenxt) currentItem.text() is a play...
I am just starting up a new project that needs some cross-platform GUI, and we have chosen Qt as the GUI-framework. We need a unit-testing framework, too. Until about a year ago we used an in-house developed unit-testing framework for C++-projects, but we are now transitioning to using Google Test for new projects. Anyone have any expe...

[Actually it is for a splash...

I want to have a plotting widget in my Qt application. Qwt provides such a widget with QwtPlot. However, I can't find any way to only display a certain part of the complete range of my data. Specifically, I want to display spectrums with a frequency range from 0 to 2^14. For the GUI however, only the audible range from ~20-20k Hz is of ...
