QML Tutorial for Beginners

QML (Qt Quick) is a declarative user interface language that makes it easy to create fun and dynamic applications. Let's dive into QML with this step-by-step tutorial for beginners:

Hello World in QML
To get started, we'll create a simple "Hello World" application in QML:

This QML code defines a Rectangle element as the root object with a size of 200x200. Inside the Rectangle, we have a Text element that displays the text "Hello World!" centered within the parent Rectangle.

	import QtQuick 2.0
	Rectangle {
	width: 200; height: 200
	Text {
	text: "Hello World!"
	font.pointSize: 24
	anchors.centerIn: parent
	}
	}

Running QML Files
To run QML files, we need a corresponding .cpp file that imports the QML module and loads the QML source:

	#include <QGuiApplication>
	#include <QQmlApplicationEngine>
	int main(int argc, char *argv[]) {
	QGuiApplication app(argc, argv);
	QQmlApplicationEngine engine;
	engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
	return app.exec();
	}

This will load the QML file at "qrc:/main.qml" and display our "Hello World!" text.

Basic Components
QML has many built-in components for creating user interfaces:

Rectangle - A contanier with width, height and color.
Text - Text display component.
Button
Image
Label
ComboBox
ListView
GridView
and many more...
That covers the basics of getting started with QML!
