Here is a small abstract about the current state of the discussion:
Some properties can not be supported on some widgetsets, because it would
require a lot of work, which no laz devel wants to do. OTOH some native
features are so great, that the LCL should support them, but only on a subset
of the widgetsets.
The main problem is how can the programmer see, what property/method is
available on what platform. The documentation is a good place, but not
sufficient. It should be marked in the OI and identifier completion as well.
The information can not be stored in the LCL alone and must be readable when
cross designing. So one solution could be a xml file in each widgetset. This
kind of information is needed by other libs as well. For example database
front/backends. So maybe a more generic solution is needed.
