Detailed Description

qx::IxModel : interface to manage Qt model/view architecture with classes registered into QxOrm context (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 :

  • Qt widgets : QTableView or QListView for example to display/modify a database table content ;
  • QML : each property defined in QxOrm context is exposed to QML engine : QxModelView module makes easier integration between QML and databases.

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 : 

// Create a model and fetch all data from database
qx::IxModel * pModel = new qx::QxModel<author>();
pModel->qxFetchAll();

// Associate the model to a QTableView and display it
QTableView tableView;
tableView.setModel(pModel);
tableView.show();

2- Here is another example in QML (with Qt5, QxModelView module works fine with Qt4 too) : 

// Create a model and fetch all data from database
qx::IxModel * pModel = new qx::QxModel<author>();
pModel->qxFetchAll();

// Associate the model to a QML view and display it
QQuickView qmlView;
qmlView.rootContext()->setContextProperty("myModel", pModel);
qmlView.setSource(QUrl("qrc:/documents/main.qml"));
qmlView.show();

And here is the 'main.qml' file content : 

import QtQuick 2.1
import QtQuick.Controls 1.0

Item {
   width: 400
   height: 300
   Row {
      height: 20
      spacing: 20
      Button {
         text: "Clear"
         onClicked: myModel.clear()
      }
      Button {
         text: "Fetch All"
         onClicked: myModel.qxFetchAll_()
      }
      Button {
         text: "Save"
         onClicked: myModel.qxSave_()
      }
   }
   ListView {
      y: 30
      height: 270
      model: myModel
      delegate: Row {
         height: 20
         spacing: 10
         Text { text: "id: " + author_id }
         TextField {
            text: name
            onTextChanged: name = text
         }
      }
   }
}

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.
