Detailed Description

A logging category can be passed to console.log() and friends as the first argument. If supplied to to the logger the LoggingCategory's name will be used as Logging Category otherwise the default logging category will be used.

import QtQuick 2.8

Item {
    LoggingCategory {
        id: category
        name: "com.qt.category"

    Component.onCompleted: {
