I have a combo, which is showing some awkward behavior. Given a list of options from the combo-box, the user should pick the name of a city clicking with the mouse. Here is the code: QtCore.QObject.connect(self.comboCity, QtCore.SIGNAL("currentIndexChanged(QString)"), self.checkChosenCity) def checkChosenCity(self): ...
I am evaluating Embedded Linux GUI toolkits for an upcoming project and have put together a must have “feature list” to help me with the decision: Color gradients in graphics (for menu headers buttons, icons, etc…) The ability to draw complex wave graphics with say a background grid, notations. The ability to swap between to landscape ...
I want to do some custom processing when the orientation of the phone changes. I have re-implemented the resizeEvent(QResizeEvent*) virtual function in my class. The strange thing is, for the first one time when the phone orientation is changed, this function is actually called, and works fine. But all subsequent orientation changes, t...

I want to add add an exception to the firewall (without changing the setup for the other firewalls options). I am using Carbon, Qt, C++. However, I feel this has more to do with some install tim...
Designing UIs with QtCreator under Windows, and porting the same .ui file under MacOSX leads to designs with some text parts very small -- actually, the HTML ones. It seems it comes from the fact that QtCreator uses pt instead of px as text size unit, and that the default screen resolutions are quite different under Windows and MacOSX. ...
hi , I just started with QT and I know the concept of signal/slot but in implementing it I have problem. take a look at my code : #include "test.h" #include <QCoreApplication> test::test() { // TODO Auto-generated constructor stub } test::~test() { // TODO Auto-generated destructor stub } void test::fireslot(){ qDebug...
Qt's QGraphicsScene provides some nice functionality out of box: user can select objects and move them around. I want one more thing - get notifications when user has finished moving the object. There are lower level events, like mouse move, press, release, but I'd not like to reimplement the functionality that is already there (moving ...
Hi I have a problem compiling my Qt app with Visual studio 2008 SP1. For the sake of purity I created a windows XP virtual machine, installed VS 2008, then SP1 and then compiled Qt 4.6. Now from looking at the manifest of the Qt DLLs (using XN Resource Editor) I can see that they depends on 9.0.21022.8 CRT. But at the same time the lat...
I realized my earlier question was a little confused about the rules and dependencies. The following .pro file generates a makefile which works correctly IF the source files in the directory 'generated' exist at the time qmake runs. idl.target = generated/qmtest.h idl.commands = code_generator idl.config = no_link idl.depends = $...
Can someone explain to me the basic idea of Qt signals&slots mechanism IMPLEMENTATION? I want to know what all those Q_OBJECT macros do "in plain C++". This question is NOT about signals&slots usage. added: I know that Qt uses moc compiler to transform Qt-C++ in plain C++. But what does moc do? I tried to read "moc_filename.cpp" files b...
I have written a C++ application that uses the Qt framework. I would like to make this application available on different platforms. Since I use Linux, I have no problems compiling the code for Linux. The questions is: Can I compile my code in such a way that it will run on Windows, Mac, etc.? As said above, I'm working on a Linux mach...
Hello everyone. Is there any good QtScript tutorial that isn't about slots or accessing c++ values from script? All I need is one function in external file that uses some regexps on array values and then sends output back to main programm. I understand, that it can be done using signals/slots, but it looks like overhead and I'm sure the...
I am currently working on an application that launches separate processes which display additional dialogs. The feature I am trying to implement is simulating modal behavior of these dialogs. More specifically, I need the application to stop processing all input, both mouse and keyboard, when the dialog is launched, and resume when it's ...

In the first column, there are only dates at this format: 2010-01-02 I want this column to show the date at this format (but without changing the real data): 02.01.2010 I know that I have to create an QItemDelegate for this column, but I don't know how I can read the existing data and...
We are moving a large codebase from GDI to QPainter. One thing we used to get on Windows easily was the EMF clipboard format, which enabled customers to manipulate their pasted output in other programs (like Office) in a vector format. It's easy for us to produce bitmaps from Qt into EMF, but that really doesn't give us back the editabi...
