Hi there Armin - the LayoutHandlers within the Reorderer are now
parameterised with "parallel" and "perpendicular" "strategies" (if Colin
has had even a thimbleful of wine this evening he is going to come after
me now :) which are used to compute the results of keyboard and other
navigation. These directions are assessed relative to the "dominant"
orientation configured into the LayoutHandler (horizontal, vertical).
Around line 576 these are mapped onto methods of the corresponding name
in GeometricManager - the one of greatest interest to you is
"that.logicalFrom" defined at line 464. In order to configure
non-wrapped navigation, the best method would be to add an extra
argument to "getRelativeElement" above it to defeat wrapping and then
define a new GeometricManager strategy and label to go with it. The best
naming would probably be to rename the existing "logicalFrom" to
"logicalWrapFrom" by analogy to "lockedWrapFrom" below it, and call your
new strategy "logicalFrom". This is fine since these methods have never
been advertised as part of a public API...
Sorry for the slight obscurity of implementation but it at least means
that this work you are doing now has a clear place to take in an
existing infrastructure of named parameterisation :P
Do ask more if there are any further obscure points -
Cheers,
A.

Hi everyone,
I am intending to work on this JIRA
http://issues.fluidproject.org/browse/FLUID-3391
The idea is to make the wrapping around in the list reorderer
configurable since it might
confuse some users (especially blind user might find it challenging to
move an item in a
list with no end).
I tried to understand how it is done but I am lost. I did some diffs of
old code that fixed
JIRA http://issues.fluidproject.org/browse/FLUID-1491
which fixes the wrapping issue.
There are not much comments in the code explaining what is going on and
I would be
happy for any help that points me in the right direction.
I will be in tomorrow morning to work on this for 2 or 3 hours.
Thanks for any hint.
Armin
