Refresh Button Widget

KNIME Quick Form Nodes version 4.4.0.v202102240912 by KNIME AG, Zurich, Switzerland

Creates a button widget with configurable text which emits reactivity events in component visualizations. These events trigger partial re-execution within a component of downstream nodes, allowing users to leverage the power of the KNIME Reactive Visualization framework and create interactive web applications and visualizations in real- time.

Interactive View: Refresh Button Widget

Displays a button with text and an optional label which emits reactivity events to re-execute downstream nodes.

Output Ports

Variable output port to connect to nodes which should be re-executed when the widget is clicked. Nodes downstream 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.
