Stored procedures
The RulerVisible property is used to:
  • Determine if a playhead is visible in a TimeLine control.
  • Show or hide a playhead in a TimeLine control.
Reminder: The playhead of a TimeLine control is a bold vertical line that represents a specific point in the control. The style of the playhead can be defined in the "Style" tab of the TimeLine control ("Selected time").
Example
// Set the playhead to 5 seconds
TL_TimeLine.RulerVisible = True
TL_TimeLine.RulerValue = 5
