*"Event handling, and the philosopher's keyboard"*
I've downloaded Stef and Igor's EventModel to play with their new event
model :). I've created KeydownEvent and KeyupEvent in contrast to the
generic KeyboardEvent with all the information. It's very simple code,
but, that is the api I'm talking about.
Gofer it
squeaksource: 'GuilleUtils';
package: 'EventModel';
load
| ann evt |
ann := SystemInputEventAnnouncer new.
ann subscribe: SystemInputEvent send: #dispatchEvent: to: World activeHand.
10 timesRepeat: [
500 milliSeconds asDelay wait.
evt := Sensor nextEvent.
evt ifNotNil: [
ann handleEvent: evt
].
].
I don't know what other people happen to think about it :/, but a simple
path to include this stuff in the image without breaking everything should
be:
1) since keyup and keydown events are not used in any morph in the core,
adding the new keydown and keyup should not break anything.
2) fetch a #keyStroke: implementor
3) if it's handling shortcuts instead of only chars (like cmd+smthg,
ctrl+smthng), create an issue "put my shortcut handling in #keyDown: please"
4) solve the issue
5) if (#keyStrokes: toRefactor) > 0 : goto 2
After all that, the keyStroke users should only be using keyCharacter, and
the refactor to use a simplified KeystrokeEvent is pretty straight forward
:).

Andreas Raab suggested here to follow the X11 table, since it seems to be
the more complete one :):
