Re: [platform-swt-dev] GTK List is done

[Steve_Northover@xxxxxxx]

First off - it's fortunate that I don't care about building Eclipse!

I did search Google for gtk_clist_moveto()to find out what people were
saying (Google also searches groups) but couldn't find a discussion of the
suggested work around.  It's a pain of course, leads to "duplication of state"
and probably flashes - wait till it's visible, then scroll.  So, I'm going to hold off
on the work around in SWT for now but keep the suggestion in mind.

Do you know the exact reason it fails in GTK?  For example, on Windows, way
back in 3.11, the text widget had this bug and it was related to the size of the widget
(a zero/small sized widget did not know how to scroll).

Yes, that's the case.  I think what people usually do is add a hack to
save what you want to move to, and move when you come onscreen, for
example. We've been encouraging a workaround here since GTK 1.2.x is
in the "don't touch it in ways that might break things" phase of its
lifecycle.

I didn't realize SWT used native list/tree - this is another painful
aspect from the 1.2/2.0 angle, since GtkTreeView is much superior from
both an API and UI standpoint to GtkCList/CTree. CList/CTree are still
in 2.0 (and likely 2.2 and 2.4 as well), but they are discouraged for
use in new code.
