qx::QxModel<T, B> : all classes registered into QxOrm context can be used with Qt model/view architecture (Qt widgets and/or QML views)
QxModelView module provides an easy way to work with Qt model/view engine with all classes registered into QxOrm context :
qx::IxModel interface provides a generic way for all models linked to persistents classes registered into QxOrm context. All methods of this class prefixed by qx call functions from qx::dao namespace and then communicate with database.
The qxBlogModelView sample project in ./test/ directory of QxOrm package shows how to create quickly a model and associate it to the Qt model/view engine (first with a Qt widget, then with a QML view).
1- Here is an example to display/modify data from 'author' table (go to qxBlog tutorial for 'author' class definition) in a QTableView :
2- Here is another example in QML (with Qt5, QxModelView module works fine with Qt4 too) :
And here is the 'main.qml' file content :
As you can see in the 'main.qml' file, 'author_id' and 'name' properties of 'author' model ('myModel' variable) can be automatically read and write (because they are registered into QxOrm context). Moreover, qx::IxModel interface provides a list of methods for QML side (Q_INVOKABLE) to communicate with database : for example, the 'Save' button will save the model in database without having to write a C++ function.
Note : a QxEntityEditor plugin generates automatically the code to manage models with relationships. Then it is possible to work with nested C++ models.
