[Thicky-dev] Back button

[Paul H. <pa...@ha...>]

Lads,

I've changed the back button processing for Thicky. This after a conversati=
on with Alan Francis as the airport on Friday.

One thing I hate about the web is the back button.  If you've done InBox ..=
 ViewMail .. Inbox .. ViewMail .. InBox (as links all in a hypothetical web=
mail app), then hit prev a few times you ar eall over the place. It is wors=
e when a post was involved. Tis hard for us as IT professions to understand=
 let alone anyone's gran.

Thicky now operates a stack concept.  Some pages are marked (they mark them=
selves) as BackPoints (like checkpoint). If you hit the back button many pa=
ges will be popped until you get to that back point.  If you hit Previous (=
yes it still exists), only a single page will be popped.  A page may late m=
ark itself as a backpoint (or unmark itself).

Seems to work well.  Try it out.

Related to this, it is possible that the previous button should dissapear f=
rom the nav bar leaving only the back button.  The point is that a page dev=
eloper may make breadcrumbs that would invoke back() or prev().

Regards,

- Paul
