As said to Bill, there won't be any changes in this area for 601. Down the road we probably won't extend the events handled for built in controls, but probably will move more towards, controls built on an isigraph. Note that grid and plot are quite complex controls and that grid has its own scrollbars. The event set for the isigraph is now complete so you should be able to do most of what you want. We really don't want to talk about this now. But suspect it will be a hot topic once the final release is out.

Subject: Liberty for Events! WAS: [Jbeta] scrollbar event


I wish I understood the event system better.  My primitive
view is that the OS sends J a bunch of events, and J decides
which ones it will handle and which it will pass to user code,
and discards the rest.

Like Bill says, nowadays J can handle a lot of events.
Why not have a foreign that lets the J app indicate what
events it will handle?  Then there will be no need
for system modification every time a user makes a
good case for an event.  The call would be something like

EVENT_HOVER 9!:51 <'hover'

to start handling the HOVER event.

For events associated with a form, the event will pass to wdhandler
to be processed in the form's locale.  The right argument to
9!:51 is the name of the handler (wdhandler will append
form_  and child_  as appropriate).

For other events, the given handler will be called directly.

Subject: [Jbeta] scrollbar event

can scrollbar trigger an event while dragging the thumb? IMO
hardware is much
faster than that of 10 years ago, more events can be handled
when running J.
