I just started implementing list box objects for production use. Is
there a "technical" good reason that the on outside call event is not available for these? Bill William W. Weale, III Business Owners Support, LLC.

Bill,
You have to use the "on outside call" event in the form method.

I'm trying to keep my code in "logical" places. Interprocess drag and
drop seems to be a natural use for lb objects. What's the logic behind having the ooc event available for subforms but not for list boxes? 8-) Bill On Nov 11, 2009, at 11:46 AM, Rudy Mortier, Two Way Communications bvba wrote: > Bill, > > You have to use the "on outside call" event in the form method. > > Hope this helps, > > > Rudy Mortier > Two Way Communications bvba ----------------- > > On 11-nov-09, at 17:44, Bill Weale wrote: > >> I just started implementing list box objects for production use.

I'm doing that as a matter of course.
But the interface allows the user to move or to copy--the copy happening if the alt/option key is pressed while dragging. If it's just a move, I need the destination object to call back to the source so its record can be deleted. I'd rather not delete until the destination drop has successfully occurred. --www On Nov 11, 2009, at 4:06 PM, Chip Scheide wrote: > if your dragging and drop try - on drop event > > On Wed, 11 Nov 2009 15:46:28 -0500, Bill Weale wrote: >> I'm trying to keep my code in "logical" places.

I havent visited my drag n drop code for some time, but as I recall I HAD to reach back to the originating object (arrays in this case) to get the needed info to correctly manage the drop - and (again as I recall) no reference to outside calls. BUT then again I wasnt updating anything from the source process On Wed, 11 Nov 2009 16:26:38 -0500, Bill Weale wrote: > I'm doing that as a matter of course. > > But the interface allows the user to move or to copy--the copy > happening if the alt/option key is pressed while dragging.

It sounds like you are putting code into object methods... You have the alternative of handling the On Outside Call in the *form method*. This may conflict with your concept of logical organization, but I believe it is flexible enough to permit the action validation you desire.

Hi Sean--
I'm aware that I can monitor for the event in the list box' form method. I can also poll an ip or process variable from LB method. I was just making the point that exposing the LB method to the ooc event seems so much to be an oversight that I wondered if there were a technical reason preventing it.

List boxes have their own unique set of form events 2. I need to communicate between 2 instances of the same object, each instance in its own process. This is really convenient because I can handle the whole operation from the beginning of the drag through validating and processing the drop in one method, even though its parts execute in different processes. > > You have the alternative of handling the On Outside Call in the *form > method*.

I agree; it's flexible enough, but not logical enough. 8-) Bill ********************************************************************** Get up to $600 to spend on Amazon.com this holiday season - http://www.4d.com/serverpromo.html 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4D.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4D_Tech-Unsubscribe@... ********************************************************************** |
