Here follows a list of the topics (in no particular order) we see a need for, in the
next time.
Best regards, Pascal
PG.01a Idle driver: after a given time w/o inputs,
execute a given program; multiple handlers can
be chained, e.g. one for pointer blanking, one
for backlight off, one for sleep mode, etc.
=> TBD
PG.01b Pointer blanking and imagery change: we have multiple sub-input
drivers (we'll probably write a superdriver and have ts, backpad
and keys as sub-drivers); each subdriver, when generating events
may change the pointer imagery and en/disable delayed pointer
blanking
=> Function to change ptr img/blking: TBD
=> super input driver: SMARTDATA
PG.02 Input driver for SoftKeys: tsinput.c should
generate key events when a pen up occures outside
the lcd area.
=> SMARTDATA
PG.03 Agree upon a convention to pass parameters to
a driver: currently via env vars. Env vars seems
okay, since passing a bunch of cmd-line params and
propagating to drivers is a bit heavy.
=> ALL
PG.04 Demo application with all widgets, and always up-to-date
=> Does it already exist ?
PG.05 Autoconf
=> SMARTDATA
PG.06 fonts: - possibility to set global default font explicitely
- for a context, possibility to set default font to
override global one
=> MICAH ?
PG.07 Do some profiling
=> TBD
PG.08 Rendering acceleration for linear 1, 2 and 4 (in C, not asm)
=> TBD
PG.09 EZ328 driver: - check cleanup after exit (xcopilot crashes)
- possibility to have the 1st lcd line off pgui
to use it as debug indicators
=> SMARTDATA
PG.10 Finder:
terminology: finder = desktop + taskbar; desktop = apps icons
- desktop: icons a la Palm, with grouping (tabs, menu ?)
- taskbar:
o when app running, a button to return to desktop
o when desktop visible, several standard indicators;
some of them also visible when app running
o indicators: area in the taskbar that app can access;
e.g. time/date, charge/battery level, alert (new SMS,
appointment), hw-module-related (e.g. GPS coordinates)
- description file for apps; format ? XML is really too heavy !!
- apps located on filesystem, url or database (TBD)
- an app may request GUI space (replacing the desktop), space in
the taskbar, or even nothing (e.g. could splash a popup upon
alert)
- server port to change config: add/remove/move app, control
taskbar
- keys (soft, hard, or gui button) call a menu with shortcuts:
favourites, and most-recent-used stuff
=> ALL: more ideas
=> SMARTDATA: implem.
PG.11 For apps wanting to show an indicator there are two possibilities:
- getting the taskbar handle, they could create a canvas in it
(currently not possible)
- making a connection to the finder, telling it to create/remove/modify
a canvas and receive click events
=> TBD
PG.12 GUI handling similar to cell-phones: Focus movable with 2 (or 4)
keys; focused widget actionned by key; in dialog boxes, yes/no
(= left/right) buttons clickable by two keys
=> TBD
