- \qmlclass Timer QmlTimer
- \brief The Timer item triggers a handler at a specified interval.
-
- A timer can be used to trigger an action either once, or repeatedly
- at a given interval.
-
- Here is a timer that shows the current date and time, and updates
- the text every 500 milliseconds:
-
- \qml
- Timer {
- interval: 500; running: true; repeat: true
- onTriggered: time.text = Date().toString()
- }
- Text {
- id: time
- }
- \endqml
-
- QmlTimer is synchronized with the animation timer. Since the animation
- timer is usually set to 60fps, the resolution of QmlTimer will be
- at best 16ms.
-
- If the Timer is running and one of its properties is changed, the
- elapsed time will be reset. For example, if a Timer with interval of
- 1000ms has its \e repeat property changed 500ms after starting, the
- elapsed time will be reset to 0, and the Timer will be triggered
- 1000ms later.
