How to create a QML object displaying the properties of a C++ object?

Question

Qt

Those. Let's say we have a spaceship object in the game. All manipulations with it (including creation and deletion) are performed on the C++ side. QML is only required to draw it on the stage according to the current properties. How can this be implemented? The main problem is to create a QML object at the same time as a C++ object and at the same time ensure that the properties of the correct C++ object are displayed.

Answer 1

It is done quite simply:

• create a ship class, all the fields of which we pass through Q_PROPERTY
  
• register the ship type in the engine
  
• we create a wrapping class that will give a list of ships through QQmlListProperty and QList (or just throw our model inherited from QAbstractListModel into the engine)
  
• we get this list in QML and draw as we want
  

Answer 2

Qt allows you to create QML from a string:

var newObject = Qt.createQmlObject(
'import QtQuick 1.0;Rectangle {color: "red"; width: 20; height: 20}',
    parentItem, "dynamicSnippet1");

Then just add/change the required fields:
