In this joint webinar conducted by The Qt Company and froglogic, you will learn about different quality assurance aspects when developing Qt applications for embedded devices, mobile or desktop systems.
The presenters will specifically introduce different tools and methods to automate functional tests of Qt and QML GUI applications. This includes automated GUI tests, behavior driven testing, code coverage and GUI coverage analysis.
To write C/C++ programs on UNIX/Linux machines, the GCC compiler is needed.
C++ programs are written and saved as .cc files.
The c++ and g++ commands compile and link C++ source files. If the compilation goes without errors, an executable file is created, with default name a.out.
The resulting executable can be executed the same way UNIX/Linux executables are executed.
The system() function is used to run system commands from C++ code.
The getpid() and getppid() functions return the process ID and the parent process ID of the program.
The fork() function provides a way for a process to run another program (process).
I would kite to know know can I notify errors from objects of classes derived from QObjects. Searching in the net, many times I've seen that if is suggested to overload the QCoreApplication::notify() member function (http://stackoverflow.com/questions/4661883/qt-c-error-handling), but I don't like it much, I would prefer to notify errors by emiting signals. For example:
