What is a QML file?

Language file used by Qt SDK, a desktop, mobile, and embedded UI development framework for C++ and QML languages; contains JavaScript-based QML source code encoded in UTF-8 format; often used to develop mobile applications and components such as buttons.

More Information

A QML file will always start with at least one import statement (since QML does not import any modules by default an import statement is necessary, or else no elements will be available). Here is a basic example of a QML file:
import QtQuick 1.0
Rectangle {
    width: 120; height: 160;
    resources: [
        Component {
            id: contactDelegate
            Text {
                text: modelData.firstName + " " + modelData.lastName
    ListView {
        anchors.fill: parent
        model: contactModel
        delegate: contactDelegate
