Thanks. That works. But looks like it only works when initially drawing the polygon as opposed to also working when editing an existing polygon. I have a similar tool to this that shows the area when drawing, just trying to figure out how to get it to work when editing an existing polygon. I was hoping to build on my own tool if there was an easy what to get a hold of some other signal that gets fired while editing.

You might want to take ispiration from their code. Regards, Harrissou Le mar. 11 mars 2025 à 15:55, Catania, Luke A ERDC-RDE-GRL-VA CIV via QGIS-Developer <qgis-developer@lists.osgeo.org <mailto:qgis-developer@lists.osgeo.org> > a écrit : I need to calculate these values on the fly while I am in an edit session resizing a polygon or a line. I need the user to see this calculation while they are editing not after the edits are committed. I already have the UI set up to capture after commit, but I need to capture while they are moving vertices and update the values in the UI, so they don’t keep editing and then committing just to see if they are close. I want them to know before they commit. Any idea how to achieve this?
