Refresh Button Widget

Adds a button widget with configurable text which can be used to refresh the composite view of the component. The button widget emits reactivity events that trigger the re-execution of downstream nodes in a component when clicked. It allows users to create interactive Data Apps and visualizations.

To use the node, connect the variable output port to the nodes which should be re-executed. The downstream nodes of those connected nodes will also be re-executed when the widget is clicked.

Output Ports

Variable output port to connect to nodes which should be re-executed when the widget is clicked. Downstream nodes of a node connected to this flow variable output port will also be re-executed, so it's only necessary to connect to the root node in each workflow branch for which re-execution is desired. The flow variable value is trivial and does not contain any information.
