How to connect c++ methods to QML

[sami.mahjoub]

Hi all,
I have 2 questions;
First, in case I already have a class that contain some methods, should I add signals to all the Q_INVOKABLE methods ?
Also, I want to know if I already have an user interafce (containing classes with methods running operations on a Data Base!) and I want to got the same in QML should I rewrite all classes to make them Shape to be used in QML ?

Thank u for any help

If your classes doesn't have any shape and you uses only pure methods, properties etc. the answer is not. In addition your class shoud inherit from QObject. In other case, if your class have shape it should inherit from QDeclarativeItem. There are many examples and tutorials. Try to read one.
Furthermore you shoud register your classes to use with qml: qmlRegisterType<your_class_as_type>("Library_name", version_nr, revision_nr, "Name_of_type_useable_in_qml");
And in qml file add import Library_name 1.0 (version.revision)
