[mobile-devel] Bible - Tree navigation for General Books

[Martin Denham]

Thanks for your inputs.

After seeing the Qt interface (nice!) I thought of using something like the
JSTree JQuery plugin in a WebView to present a tree to the user but I have
concerns that it might not look very consistent with the rest of the app and
Android in general.

Then I realised that we already have a (sort of) tree based key in the main
bible modules i.e. book/chapter/verse, and that was originally presented
using ListViews on a series of pages.  So my current thought is to do a
simple series of ListViews drilling down the tree, similarly to the original
chapter/verse navigation, at least for the first implementation.  Clearly
this will be consistent with Android and would have been consistent with the
rest of the app if we had not migrated to grids for bible nav.  For
consistency I could try using a grid to represent GenBook tree keys but with
variable size names it would end up a mess.
