Fixed that now.

I think this sort of feature is important, because it is has a long
tradition
in GUIs. VID is a remarkably small GUI framework and I believe RT
will evolve these sort of features in VID over time. Or someone else
will produce a framework that satisfies the standard features list.
A work in progress I guess.
Back to the code.
I've worked out now that by testing for mouse down I can set the focus.
I went on provide tabbing between multiple checkboxes.
For bonus marks, I tried highlighting which checkbox actually has focus.
I haven't thought about how to apply such findings to other styles.
I also don't know if I've broken any VID rules, so I don't know
how or whether it can be applied more generally.
But maybe it is a couple of steps closer.
modified-check-feel: [
; Basic highlighting of the checkbox with focus
redraw: function [face action pos] [bvlc cond-c cond-f] [
cond-c: equal? face/edge/color bvlc: svv/vid-colors/bevel
cond-f: equal? face system/view/focal-face
if equal? cond-c cond-f [
face/edge/color: either cond-f [black] [bvlc]
]
svvf/check/redraw face action pos
]
; Space bar toggles check - tab moves to next tabbed item
