[Pythoncard-users] Multiple Selection List

[Michele C. <mca...@in...>]

Hi,
following the same approach of PythonCard's components, I
tried to add a multiselection list (as opposed to the single
selection one avaialable 'List') by simply copy-paste-modify
the code for List in list.py under components.  
Aside from the type field, which contains LB_MULTIPLE
instead of LB_SINGLE, a couple of changes in the getter and
setter and the class name not much was needed.
Problems arise though when I open the layout editor.  First
of all, the MultiSelList doesn't appear in the components
list.  Furthermore, when I click on List to instantiate a
new layout component, it actually instantiate a MultiSelList
instead of the usual List. I suppose there is something
going on with the registration of the class with the engine,
as the console spits an error out because the class key
lookup for MultiSelList in the component class dictionary
failed (in registry.py).

I also tried adding the new component in a another folder
appcomponents as that seems the way suggested.  No luck.

Do you have any hint on what it takes to add this new
class/component or alternatively extend the current 'List'
to be either ways (multi selection AND single selection
(default so that it does not clash with the tools already
developed)?

My Best Regards,
Thanks for this amazingly simple GUI framework.
