Quoting Milos Prudek :

How are the various GUI widgets defined in Script-Fu?

For instance Script-Fu/Decor/Fuzzy border: - Border size GUI widget is a "number with arrows". - Granularity GUI widget is a "slider with arrows".

I look at the fuzzyborder.scm file. These GUI widgets seem to be defined in "(script-fu-register)":

SF-ADJUSTMENT _"Border size" '(16 1 300 1 10 0 1) SF-ADJUSTMENT _"Granularity (1 is Low)" '(4 1 16 0.25 5 2 0)

They are both SF-ADJUSTMENT, so why is the first GUI a "number with arrows" and the second is "slider with arrows"? And what do the numbers (16 1 300 1 10 0 1) mean?

The last argument determines the widget type. The list of numbers corresponds to (respectively):

'initial_value' -- starting value (subsequent calls will use LAST_VALUE instead)
'minimum' -- lowest value possible
'maximum' -- highest value possible
'step_size' -- amount to increment/decrement if clicked with mouse button #1 'page_size' -- amount to increment/decrement if clicked with mouse button #2 'digits' -- the number of decimal places: 0 = integers, 1 = tenths, 2 = hundredths, ...
'widget_type' -- 0 = slider, 1 = spinbutton

@ Sven Neumann, thanks for clarifying how the interaction mode works.

Wow. Thank you. Is this documented somewhere?

It is documented in test-sphere.scm which is distributed with the source code. It would be nice if someone turned this into a document that we could publish on gimp.org.
