Introduction
Re-register to feedback from the video system when either
the video system or the control system restarts
Create a user interface
When either the video system or the control system restarts, the control system
must re-register to the events that the video system sends when someone uses
the Touch 10 in-room controls or pushes a new in-room control panel to the
API for in-room control
Touch 10.
Widgets For terminal output mode:
xfeedback register event/UserInterface/Extensions/Widget

Initialize all widgets
It is important that the control system initializes all the widgets on the Touch 10
in-room control panel in the following situations:
• When the control system connects to the video system for the first time.
• When the video system restarts.
• When the control system restarts.
• When a new in-room control panel is exported to the video system (as
response to a LayoutUpdated event).
If this is not done, then the Touch 10 may show incorrect values and not truly
reflect the status of the room.
Use the command to set the initial values.
SetValue
Always send values back to the video system when
something changes
To avoid unexpected behavior and ambiguities, the control system must
send commands to the video system when something changes. This
SetValue
applies also when the change is triggered by someone using the controls on
the Touch 10.
For example, it makes no difference if you use a slider on the Touch 10 in-
control panel to dim the light, or a physical dimmer in the room, or another
touch panel. The control system must always send the dimmer value back to
the video system using the
