qml qrc alias

In QML, the qrc alias is used to specify the location of resources such as images, videos, and other assets in a Qt Resource File.

The qrc alias allows you to refer to these resources using a simple syntax, making it easy to manage and access them in your QML application.

To use the qrc alias, you need to first define it in your QML file using the following syntax:

import QtQuick 2.0

QtObject {
    id: resourceRoot
    property alias myImage: Qt.resolvedUrl("qrc:/images/myimage.png")
}

In the above example, we are defining a qrc alias called "myImage" that points to the image file "myimage.png" located in the "images" folder of our Qt Resource File.

We can then use this alias to load the image in our QML code like this:

import QtQuick 2.0

Rectangle {
    width: 100
    height: 100
    Image {
        source: resourceRoot.myImage
    }
}

By using the qrc alias, we can easily load resources without having to worry about their absolute file paths, making our QML code more flexible and easier to maintain.
