I'm afraid this seems to be missing in the documentation. If you add a resize method to your extension, that will be called on resize, not the paint method.</P><P></P><P>Erik Wetterberg</P><P></P><P>If you find this helps you, please mark the answeras helpful and/or correct.</P></BODY></HTML> Mon, 05 Feb 2018 09:04:19 GMT https://community.qlik.com/t5/Integration-Extension-APIs/How-to-know-if-a-repaint-was-triggered-by-new-data/m-p/49441#M741 ErikWetterberg 2018-02-05T09:04:19Z
