Need sample code for custom KNIME node to show busy processing

KNIME Development
#1

Need some visual clue to show a custom KNIME node busy processing.  Currently, the KNIME node is just doing processing without any visual clue that it is doing that.  The KNIME node could run for many hours.  Some simple GUI implementation, such as constantly being updated short text, blinking dot or moving progress bar would do.  If there is some sample code around, please point me to it.

Thanks in advance.

Use ExecutionContext.setProgress(...) in your execute method. The ExecutionContext is passed as parameter.

Thank you Thor.  It works well.  The custom node becomes very informative when the setProgress() call is added in the execute() method.
