Re: [Jgeneral] wd setlocale
The patch that I sent earlier is backward compatible: it will allow just "event" verb in child locale, while preserving the three existing handlers with the priority: - PID_handler - PID_CID_event - event_CURRENT_ <-- new - PID_default http://www.jsoftware.com/pipermail/general/2008-March/031629.html Note 1: the event_CURRENT_ is processed only if "syslocalec" is non-blank AND "event" verb exists. Note 2: in locating child handler in control locale, inheritence need to be considered to allow cascaded handlers. E.g. base-->mouse gesture-->pan/zoom handler-->image viewer. But I believe it works so already: nc<'names' 3 nc<'names_base_' 3 nc<'names_z_' 3 > Analogously, if wdhandler is called in a form object locale, would you like > the option that wdhandler just call event? No, that's not feasible and will break existing code. In particular, form locale should be able to handle events for multiple form IDs. In contrast to form locale handler, in control locale the control ID and the form ID are known and unique for a given instance of control object. For form locales though, the difference between form instance and "static" form locale is only ability to create multiple forms simultaneously. Whereas within the (either type of) locale you still need to distinguish between form IDs and control IDs.

Re: [Jgeneral] wd setlocale
If wdhandler is called in a child object locale, you would like wdhandler to
just call event. Makes sense.
Analogously, if wdhandler is called in a form object locale, would you like
the option that wdhandler just call event?
The point is that PID and CID are probably not needed and indeed are a
nuisance if called in an object locale.
We can't make the change for forms as too much would break. Perhaps a form
style could indicate this option. Perhaps a setlocale parameter could select
the plain event option. In this case the changes would be to the wd'q'
result and not to the wdhandler definition.
Your point deserves attention. It would be nice if it can be done in a
manner that is backwards compatible, is clean in 603, and doesn't require to
much messing around with 602.

Up to calling wdhandler is fine.
The problem is in what wdhanlder is calling.
It is currently calling verb:
PID_CID_event''
So it prevents having generic controls without
creating every time the cascade of verbs:
PID_CID_event=: event
for each instance.
To fix this, wdhandeler should call simply
event''
if it exists or proceed as it does right now
otherwise.

The intent of wd'setlocale' is that wdhandler is called in the desired
locale. In the splitter example this would be in the object locale of the
splitter class. There should be no requirement for wdhandler to look at
syslocalec, just as there is no need for it to look as syslocalep.

Here's a pattern for "wd setlocale" from jsplitter.ijs:
(PID,'_',ID,'_paint')=: paint
(PID,'_',ID,'_mbldown')=: mbldown
(PID,'_',ID,'_mblup')=: mblup
(PID,'_',ID,'_mmove')=: mmove
HWNDC=: wd 'qhwndc ',ID
wd 'setlocale ',ID,' ',>coname''
It seems to beat the raison d'etre of "wd setlocale":
if it is necessary to create event verbs
for each control instance, that's no better
than before--when such event verbs were defined
in parent form as handlers in control locale:
(PID,'_',ID,'_mmove')=: ('mmove_',ctl_loc,'_')~
what would be really nice, is if it weren't necessary
to define event verbs; "wd setlocale" should suffice
to tell that for such parent and for such child id
here's the locale (control instance) that would have
the handelrs in the simple form "mmove" (without "PID_ID_"):
mmove=: 3 : 0
... do move
)
Maybe it's already there and somebody does not
fully understand something. If it's not there it
should be easy to realize such logic in the main
wdhandeler based on the wdq values.
