If you want to use the checkbox, then you could change the way it works
The below code, substituted in pyvcp_widgets.py, will create an extra IN pin called pyvcp.{whateveryounamedcheckbox}.changepin
It toggles the state of the checkbox, when set TRUE.
(it will not toggle again until pin goes FALSE to prevent a race condition)
Activating will either check or uncheck the checkbox, depending upon its current state, user click on the checkbox will revert the state.
As with all parsel-tongue, be very careful of indentation if you cut and paste this
You can amend to suit.
For instance: if you will only ever want to uncheck the box, just change the conditional test in update()
so that it only toggles the value in self.v if that value is true.

EDIT added another reset of IN pin to ensure it is done, whatever the result of the conditional test
Thank you for providing this! This is just what I was looking for. I need a checkbox that I can reset after a particular operation so that the user always has to click it, if needed, before starting the operation again. I like it!
[strike]One newbie question, however. I see in the lib directory that there is a pyvcp_widgets.py file and a pyvcp_widgets.pyc file. If this change is made to the .py file, is there some kind of compile step required to make the .pyc file before it can be used?[/strike] Update: Ignore this question, I found the answer in your other posts.
Another question, however, is if, instead of 'changepin', I could simply have a 'statepin' where you can actually set the state to 0 or 1? I would think this would be straightforward, but I'm confused by the role of the 'reset' attribute... Perhaps it's to address the fact that this is toggling, rather than setting the value?
