If you want to display what sources are routed to a particular set of router outputs the way to do this is using a new property of our Output Selector control.

Source Labels on Output Selectors

region

From Helm 4.3.0.5 onwards, Output Selectors have a new property called “SourceLabels”. This property controls the appearance of current source names on output selector buttons. To show the source names, set the SourceLabel Opacity to 1, and use the SourceLabel TextTop property to position the Source Labels within the buttons.

The source labels will update whenever the routes are changed, and will also follow changes to the current group of the Output Selector.

By changing the styling of buttons and text opacity the Output Selector can also become a simple routing status indicator.
