PYVCP - SCALE Widget - Set Initial value

I've created some really nice panels now... I usually include a SCALE widget to control the jog feed rate.

Typically this scale will go from 1 to 60... depending on the machine... and as such, will initially come up as 1. I always forget that... and click a jog button... then wonder why the machine "didn't move"... but it did... just VERY slowly. So I wanted it to start up faster than that.... a different initial value.

Here is the typical code I use...
<vbox>
<relief>RAISED</relief>
<bd>2</bd>
<label>
<text>"Jog Speed"</text>
<font>("Helvetica",10)</font>
</label>
<scale>
<font>("Helvetica",10)</font>
<halpin>"jog-speed"</halpin>
<orient>HORIZONTAL</orient>
<resolution>1</resolution>
<min_>1</min_>
<max_>60</max_>
</scale>
</vbox>

I wanted it to start off initially as 15 instead of 1... so I looked at the SPINBOX widget which has
<initval>15</initval>
So I decided to give it a try... the PYVCP document didn't say anything about it... but I figured it would probably work. ;)

It works!
(Just wanted to pass that info along to someone else who might need it.)

Here is the code I used if you want to tinker with it...
<vbox>
<relief>RAISED</relief>
<bd>2</bd>
<label>
<text>"Jog Speed"</text>
<font>("Helvetica",10)</font>
</label>
<scale>
<font>("Helvetica",10)</font>
<halpin>"jog-speed"</halpin>
<orient>HORIZONTAL</orient>
<resolution>1</resolution>
<initval>15</initval>
<min_>1</min_>
<max_>60</max_>
</scale>
</vbox>

I looked in the manual and initval is indeed in the scale description.

I just looked again... you are right... I must have missed it.
(2:00am programming caught up with me I guess.)

Thanks,
Jerry

That's up to you, if you edit the original post to just explain what you did it would be informative to others that search the forum.

I'll leave it... you are correct... it could help another coffee deprived programmer...
