This is simplest way to use openui5 widget with RWebWindow.

It is normal xml::View, but controller should be derived from rootui5/panel/Controller. This class provides methods, which simplify handling of communication between server and client

First of all, when creating RWebWindow, one should configure panel name. Like:

 auto win = ROOT::RWebWindow::Create();

 win->SetPanelName("localapp.view.TestPanel");

Namespace "localapp" in this case corresponds to openui5 files, which will be loaded from current directory. Therefore "localapp.view.TestPanel" means view, which will be loaded from ./view/TestPanel.view.xml file.

Controller is configured in the XML file and called "localapp.controller.TestPanel". Means it will be loaded from ./controller/TestPanel.controller.js file.

In the controller one use onPanelInit and onPanelExit methods to handle initialization and close of widget. Method panelSend should be used to send string data to the server.
