Qt Core

LieberLieber Embedded Engineer supports Qt Core features such as QObject, QEnum, QSlot and QSignal by extending the class, function and/or attribute with a Q[name] Stereotype.

Implementation taken from the new Components Test Model

QT Core

QObject

By adding the qobject stereotype to a class, the code generation (for C++) will generate the following.

a header to include QObject
an inheritance of the QObject base class
adds the Q_OBJECT macro to the class

QEnum

By adding the qenum stereotype to a class, the code generation (for C++) will generate the following.

an enumeration to use with another class
when used inside another class, an attribute with the Q_ENUM macro

QSlot & QSignal

qslot and qsingal Stereotypes can be assigned to operations and will create Qt slots and signals.

In Qt signals and slots are used for communication between objects and are an alternative to callback techniques.

A signal is emitted when a particular event occurs. A slot is a function that is called in response to a particular signal.
