while editing
Hi,
There is a CalcArea2 plugin whose description mentions it should be doing that
for polygons. You might want to take ispiration from their code.

:
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?
