Controls and properties
Controls are the basic building blocks of overlays which are used to visualise data
- A control can be used on its own to display data.
- You can create gauges by placing controls together on the design area and configuring them individually to work as a whole.
- When you add controls to the design area, they automatically get assigned to the default group. You can re-assign them to other groups using "Group" property.
- Properties of the controls in Advanced overlay editor are highly configurable.
- Most of the properties can be configured with two values; default value and run time value.
The run time value of a property can be any one of the following:
- text string, numeric or an empty value
- A variable: For example to show the speed we can set the variable VAR_0015
- Reference to a custom (user) property definition E.g. [0], [1] …
- An equation consist of Variables, Mathematical functions, Conditional statements, and custom (user) property references.
The application supports the following control types:
- Bitmap - This is used to display a static image to the user
- Simple Text - This is used to display a static text to the user
- Digital Display - This is used to display variable information in the form of a digital number
- Track Map - This control is used to draw the path traversed by the vehicle
- Dynamic Line - A versatile data display control that can be configured to display data in different ways
- Video Source - This is used add PIP videos to the overlay
- Graph - This is used to display a line graph to show how the value of a variable changes over time
