Scheduler

Current Time Indicator

Documentation

This example shows how to enable the current time indication. The switches under the Scheduler allow you to specify how to indicate the current time: by using a specific indicator, shading or both of them. You can also specify how often the Scheduler updates their position using the «Update position in» number box under the widget.
