Hi ArcEye.
Thank you for your efforts.
As I told to you I've not the expertise to make this kind of job.
So I really appreciate what you are doing and your ability to break the code.

Just a lowly user and hacker
I don't have push rights and have to rely on the submissions process to work.
I wasn't thinking of anything as complicated as that.
Just a directory tree that can be tar-balled, with the changed and added files at the appropriate levels.
I have stuff littered all over, which is why I went for the repo. I need to practice with git, so that seemed a good way to do it
I imagine a lot of your stuff is in configs, so that will carry over without problems so long as the bits they rely on get put back
regards

I was under the impression that you are a regular contributor and developer

The shadow tree idea is a bit of a challenge as I have not done this kind of thing for many years. You wont think that I wrote production control and release systems based on CVS for huge production systems. And that all done from remote servers. Now I feel stupid if I cant control what is happening on my source.

I figured out eventually why I kept getting notifications about this thread - I wrote the stuff and couldn't remember 
If all else fails, read the code
If you set param_pin to 1 in your .xml file, a pin will be created which can be used to update or read the value of the spinbox.
If you read through there are come other widgets I did the same with.
Seem to recall I wrote a component that saved all the values to file and reinstated them at next startup too, but that was a long time ago

class pyvcp_spinbox(Spinbox):
""" (control) controls a float, also shown as text.
reacts to the mouse wheel.
<spinbox>
[ <halpin>"my-spinbox"</halpin> ]
[ <min_>55</min_> ] sets the minimum value to 55
[ <max_>123</max_> ] sets the maximum value to 123
[ <initval>100</initval> ] sets intial value to 100 TJP 12 04 2007
[ <param_pin>1</param_pin>] creates param pin if > 0, set to initval, value can then be set externally, ArcEye 2013............
</spinbox>

self.param_pin = param_pin

halparam = "spinbox." + str(pyvcp_spinbox.n) + ".param_pin"
self.halparam=halparam
pycomp.newpin(halparam, HAL_FLOAT, HAL_IN)If you set param_pin to 1 in your .xml file, a pin will be created which can be used to update or read the value of the spinbox.
