What is MOC in Qt?
What is MOC in Qt?
The Meta-Object Compiler, moc, is the program that handles Qt’s C++ extensions. The moc tool reads a C++ header file. If it finds one or more class declarations that contain the Q_OBJECT macro, it produces a C++ source file containing the meta-object code for those classes.
What is Q_OBJECT?
QObject is the base class for all Qt classes, Q_OBJECT macro is used to enable meta-object features in classes and finally moc is a preprocessor that changes Q_OBJECT macro instances to C++ source code to enable meta object system mechanism in the class in which it is used.
What is meta object in Qt?
Qt’s meta-object system provides the signals and slots mechanism for inter-object communication, run-time type information, and the dynamic property system. The meta-object system is based on three things: The QObject class provides a base class for objects that can take advantage of the meta-object system.
What is meta object code?
A meta object code in Qt environment is a C++ source file that is an expanded version of the C++ source file where you’ve put Q_OBJECT (and/or other related macros). The meta object code will have your implementation plus some other extra (meta) code so that signal and slots mechanism work.
What is UIC in Qt?
This page documents the User Interface Compiler for the Qt Widgets module. The uic reads an XML format user interface definition ( . ui ) file as generated by Qt Designer and creates a corresponding C++ header file.
What is Qt RCC?
The rcc tool is used to embed resources into a Qt application during the build process. It works by generating a C++ source file containing data specified in a Qt resource (. qrc) file.
Why is the Q_OBJECT macro required in this class definition?
Actually, the Q_OBJECT macro is only required if meta-object code has to be produced by the moc tool in order to use the signals and slots mechanism, the run-time type information, the dynamic property system and translating features for internationalization.

What is UIC Linux?
The uic reads a user interface definition (. ui) file in XML as generated by Qt Designer and creates corresponding C++ header or source files. It also generates an image file that embeds raw image data in C++ source code.
What is QRC Qt?
what is a . qrc file? The Qt Resource Collection File is stored in the QRC format and is affixed with the QRC extension, and is used by the Qt application and toolkit. These QRC files are generally classified as settings file that contain a list of application resources like image files or icons in XML format.

What is Qqmlapplicationengine?
The QmlApplicationEngine is all you need to set up your qt quick window, pick up the right translation files and it implicitly connects the application quit() signal to your root window.
