You mean the increment size used by the "spinner" widget (button
with paired up & down arrows)?

Right click on the spinner arrows and select from the menu
that appears. I'm not sure if there is a way to do this by
program control.

The default behavior is add/subtract (as opposed to multiply/divide),
and the default increment depends on the smallest significant
digit of the initial value.

Examples:
<pre>initial value step size
0-9 1
3.141 0.001
90 10</pre>

There is no way under program control to set the increment/decrement value for default field editors. That would require a new method to the ValueFieldEditor
class, see:

and/or yet another optional argument to
xvalue and xpvalue.
