Learning best practices of QML coding

It is important to follow certain best practices while coding in QML. You should keep the file under a certain line limit and should have consistent indentation and structural attributes, as well as following a standard naming convention.

You can structure your QML object attributes in the following order:

Rectangle {
// id of the object
// property declarations
// signal declarations
// javascript functions
// object properties
// child objects
// states
// transitions
}

If you are using multiple properties from a group of properties, then use group notation, as shown next:

Rectangle {
    anchors { 
        left: parent.left; top: parent.top
        right: parent.right; leftMargin: 20
    }
}

Treating groups of properties as a block can ease confusion and help relate the properties with other properties.
