Hey @mocoloco,
Should, that's why I asked.
Yeah, that is not the style of the classic API, there are only little error messages and things like that. What you can also do, is use the return value of SetParameter, a boolean. It will be False when setting the parameter failed.
I used 'Ge' to design all [...]
Eh, I understand, you mean from GeDialog, or what? I think it just stands for GenericDialog, it also pops up in thing like GeListNode or GeClipMap. There are some really old entities in the classic API and naming conventions were different then 😉 Ge is at least not a name for interface gadgets in our APIs.
Cheers,
Ferdinand
