not dived and tray or scoreboard focussed. This lets platform decide
to display top-level focus via mods to all elements. Second, when
moving focus to top level from dived, claim not to have handled the
key event (but return true if needs redraw). This allows platform to
handle shifting focus without requiring callback (which removed.)
the next object using a callback to the platform to determine what, if
any, object is next. Adjust curses platform to cooperate. Works
well. Palm is next.
scoreboard and tray on palm; make center drill into the focussed object and
spacebar come back up then move the focus among them. Integrate with other
focussable objects on main form. Go from separate drawCursor routines to
same for all three, with cursor only visible when focus is drilled down.
On curses, add a hilite rect routine that can be called after text is laid
down, and use for cursors.
util_trayHiddenChange, which means an API change. In board, calculate
bottom of board based on bottom of tray when tray is hidden, and round
so that it's an exact multiple of cell height. In wince, take
advantage of the new parameter to fix the scrollbar so that very
constrained boards can be scrolled even when the tray is hidden.
distinction between obscuring and completely hiding. In former case,
erase the tray rather than draw it partially hidden. This means
drawing the tray before rather than after the board, which is a big
change that so far doesn't seem to have hurt anything. If it does, it
might be necessary to draw it before and after the board.
