Re: Drag and Drop in a locked field
Bonjour Bob, In some apps I am using the following script. It is an adaptation to drap and drop inside one field, of a script from Eric Chatonet he had written for drag and drop from one field to another. Besides the field, this script uses an extra field name tempo which allows to see what line one is dragging. A bug (# 6823) prevented this script to work well in a grouped field (but the Slug had writte a workaround). Seems that now this bug has been fixed : I just tried the script on a grouped field and it works.

Thanks I already went with GetInLine and I like the way it looks. Scott's stuff is always visually pleasing. Paypal donation on the way!

Re: Drag and Drop in a locked field
Sorry, its been awhile since I worked on it and so I should clarify: the 7766 bug only rears its head after using the pop-up menu. If you disable the pop-up menu option the drag drop works fine on x86. -- Mark -- View this message in context: http://runtime-revolution.278305.n4.nabble.com/Drag-and-Drop-in-a-locked-field-tp4374946p4377399.html Sent from the Revolution - User mailing list archive at Nabble.com. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Thanks Mark! Bunch of friendlier people I have never known! :-) So far I am using Scott's Getinline solution. I like his little drag insert graphic!

Re: Drag and Drop in a locked field
Thanks I will give it a go. I have it partially working, but I found if I drag too fast the engine selects another line before dragStart is triggered. Also I had to send dragEnter from the dragStart handler otherwise the process never kicked off. I tried sending dragStart in a mouseDown handler, but that didn't seem to fix it. Weird. This sort of thing should be automatic in the engine IMHO. Seems like a common thing to want to rearrange lines in a list by dragging and dropping.
