Wow, I didn't think that would get broadcast to the world. ;-)

I'll just weigh in here briefly about the expectations from the Gtk#
|
||
|
|
side. Don't want anyone to think I'm ignoring the discussion. We are
|
||
|
|
definitely interested in a databinding solution for Gtk#.
|
||
|
|
|
||
|
|
Some observations:
|
||
|
|
|
||
|
|
Everyone seems to jump right to the tree model when they think
|
||
|
|
databinding. I'm not sure this is the best approach, although I
|
||
|
|
understand that TreeView/ComboBox are big draws.
|
||
|
|
|
||
|
|
If I were to approach a databinding solution, I would start with
|
||
|
|
something like a data bound checkbox and build the infrastructure it
|
||
|
|
takes to hook that into a "DataSource" and "Field". When you start
|
||
|
|
thinking this way, it becomes clear that the hooks for this need to go
|
||
|
|
deeper, at the Gtk.Widget level, probably.
|
||
|
|
|
||
|
|
While I'm not certain we want to follow the .Net mechanism exactly, I
|
||
|
|
want the user interface aspects to parallel the way databinding is
|
||
|
|
exposed in SWF. If we can reuse System.ComponentModel features to make
|
||
|
|
our lives easier, so much the better. We should try to better
|
||
|
|
understand how mono's System.Web and SWF databinding works before trying
|
||
|
|
to implement a solution for Gtk#.
|
||
|
|
|
||
|
|
I think it's good to pursue this is an external project for now as you
|
||
|
|
are doing. The majority of the code should probably be
|
||
|
|
internal/non-public API with the exception of the
|
||
|
|
DataSource/Field/etc... API. With proper planning, it should be
|
||
|
|
possible to develop as a standalone project to be merged into Gtk# when
|
||
|
|
it matures. Of course, since I'll have to maintain it going forward, it
|
||
|
|
will need to meet the standards that typically apply: coding standards,
|
||
|
|
readability, etc...
|
||
|
|
|
||
|
|
I'll follow your efforts as closely as I can and give feedback. Please
|
||
|
|
keep us posted.
