How can i get the values from a ETO form back to canvas in real time ?

Are you showing the forms through a cusotm plugin or via the script components?

Ah sorry, Python’s not my thing. @eirannejad can maybe help?

Hi vanderwee dario,

Here’s an example of live interaction with the eto window via a scripted component.

After the update, ghenv does indeed work without an error. However, expiring/recomputing from within the ValueChanged callback doesn’t seem to propagate to the rest of the canvas: I tested comp.Document.Solution.DelayedExpire(comp), comp.ExpireSolution(True), and the latter wrapped in Rhino.RhinoApp.InvokeOnUiThread() — in all three cases, the connected output Panel keeps showing the old value until I manually click “Run” in the external script editor. Any idea what’s still missing here, or is this simply not fully implemented yet in this build?
