Hi sylia,

please read this tutorial: https://tech.knime.org/developer-guide

You will use a SettingsModelString in combination with a text field or some input box, there are a number of dialog components.  Referring to https://tech.knime.org/developer/example-nodemodel in line 101 you can get the string by m_colSel.getStringValue().

Best, Frank

Thanks Frank  :)
