Okay, so here you go:
types.h
#ifndef TYPES_H
#define TYPES_H
#include <QObject>
#include <QVector>
#include <QVariant>
#include <QVariantList>
struct Bottle
{
Q_GADGET
Q_PROPERTY(QString name MEMBER m_name)
Q_PROPERTY(qreal size MEMBER m_size)
public:
QString m_name;
qreal m_size;
};
class DataSource : public QObject
{
Q_OBJECT
public:
Q_INVOKABLE QVariantList getData();
};
#endif // TYPES_H
main.cpp
#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QQmlContext>
#include "types.h"
QVariantList DataSource::getData()
{
return {
QVariant::fromValue<Bottle>({ "First bottle", 0.75 }),
QVariant::fromValue<Bottle>({ "Second bottle", 0.70 })
};
}
int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;
engine.addImportPath(QStringLiteral("qrc:/"));
QUrl url(QStringLiteral("qrc:/main.qml"));
QObject::connect(&engine, &QQmlApplicationEngine::objectCreated, &app, [url] (QObject * obj, const QUrl & objUrl) -> void {
if (!obj && url == objUrl)
QCoreApplication::exit(-1);
}, Qt::QueuedConnection);
DataSource source;
engine.rootContext()->setContextProperty(QStringLiteral("DataSource"), &source);
qmlRegisterUncreatableType<Bottle>("Example", 1, 0, "Bottle", "");
engine.load(url);
return app.exec();
}
main.qml
import QtQuick 2.15
import QtQuick.Window 2.15
import QtQuick.Controls 2.15
import Example 1.0
Window {
id: mainWindow
visible: true
width: 300
height: 200
title: qsTr("Some title")
Component {
id: template
Text {
text: "defaultText"
}
}
Column {
Component.onCompleted: DataSource.getData().forEach(function(element) {
template.createObject(this, { text: element.name });
}, this)
}
}
PS. QML is damn annoying ...
