Defines a logging category in QML. More...
| Import Statement: | import QtQml |
| Since: | Qt 5.8 |
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" defaultLogLevel: LoggingCategory.Warning } Component.onCompleted: { console.log(category, "message"); } }
Note: As the creation of objects is expensive, it is encouraged to put the needed LoggingCategory definitions into a singleton and import this where needed.
