If you look at the docs for handle-gesture, it says "Outputs f if the
gesture was handled, and t if the gesture should be passed on to the
gadget's parent.".
http://docs.factorcode.org/content/word-handle-gesture,ui.gestures.html
I would guess it's because your editor is wrapped by a main-gadget and any
actions that are ui.commands are "handled" by the editor and not passed to
the parent gadget.
https://github.com/slavapestov/factor/blob/master/basis/ui/gadgets/editors/editors.factor#L425
So, "left" is handled (meaning ``f`` don't pass to parent):
IN: scratchpad T{ key-down f f "LEFT" } <editor> get-gesture-handler .
[ \ previous-character invoke-command ]
IN: scratchpad T{ key-down f f "LEFT" } <editor> handle-gesture .
f
But, "up" is not (because it isn't a multiline-editor):
IN: scratchpad T{ key-down f f "UP" } <editor> get-gesture-handler .
f
IN: scratchpad T{ key-down f f "UP" } <editor> handle-gesture .
t
If you want an editor that always passes gestures, then...
TUPLE: my-editor < editor ;
: <my-editor> ( -- editor )
my-editor new-editor ;
M: my-editor handle-gesture call-next-method drop t ;
Hope that helps!
