So it *is* inconsistent. Or, at the very least, poorly documented. And, for my purposes, if the PowerButton can received a resizeControl handler, I'd really like to see the PDF widget get the message also. The XPDF external requires, as its target for a drawing area, a Graphic inside a Group, and the containing group gets resizeControl. You can use that resizeControl to show/hide scrollbars as appropriate based on zoom; set the scroll to keep a highlighted part of the PDF in view when resized; and more. For a migration path from the XPDF External to the PDF Widget, the PDF Widget should support resizeControl as well. ___ 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

Re: resizeControl wishes...
Thank you Richard. I see what the issue for me was. Groups do indeed receive a resizeControl message automatically if the rect is changed by script. However, the message (resizeControl) use seems inconsistent. For example, while a group does received the resizeControl message, a field does not seem to. Also, what I specifically ran into was that the PDF Widget does not received a resizeControl handler (and it would be really useful if it did!) I'll submit an enhancement request (below) for adding resizeControl to the PDF Widget (assuming it's possible), but I don't have the time to determine what widgets support resizeControl and which don't and what LC objects (other than groups) support resizeControl and which don't. https://quality.livecode.com/show_bug.cgi?id=24437 ___ 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

He's asking about resizing that takes place outside of direct user interaction with the pointer tool, such as during a resizeStack event. Paul Dupuis wrote: > resizeControl is sent "only sent when the user resizes a control by > dragging its handles.

IIRC the change you're looking for was introduced way back when the DataGrid premiered. Without it the DG wouldn't be able to cleanly update its internal groups. Here's a simple test stack confirming the change: https://fourthworld.net/lc/Resize%20Confirmation.livecode -- Card script: on resizeStack set the rect of grp 1 to the rect of this cd end resizeStack -- Group script: on resizeControl put item 2 of the loc of this card into tMid set the rect of fld 1 to the left of me,the top of me,the right of me,tMid set the rect of fld 2 to the left of me, tMid, the right of me, the bottom of me end resizeControl Tip: Set the lockLoc of such groups to true, to override the engine's default behavior of adjusting group size to fit contents. Now that the engine sends resizeControl to groups under both user interaction and script directive, handling the resizeStack message is MUCH easier than before. Among other things, it lets you encapsulate code within groups for reuse. But even if your groups are one-offs not needed elsewhere, the benefits of encapsulating the LOGIC of putting things where you want them is immense. It's so much easier to express the placement of objects within a group than relative to the group within a card. I'd guess that not having this sooner, and not documenting it after delivery, may contribute to the cottage industry of clck-click-click-click-click-click-click-click-click-click options for handling resizing with things like the Geometry Manager and various other tools and options. All of them are utimately responding to the resizeStack message, but in a generalized way that adds a large layer of complexity, and sometimes uncertainty. Handling resizeStack directly is with-the-grain; it uses the power of the engine to its most efficient, preditable, and robust advangage to put things exactly where you want them. -- Richard Gaskin FourthWorld.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

If you *change* the size of a group by script, then that group *does* receive a resizeControl message. Note that it does *not* receive a mesage just because the rect changes - only if the size changes. So if you do something like repeat 10 times add 1 to X set the rect of grp "A" to X,Y, X+100, Y+100 end repeat then grp "A" will get either 0 or 1 message (from the first time through the loop). If you do repeat 10 times add 1 to X set the rect of grp "A" to 100,Y, X+100, Y+100 end repeat it will receive either 9 or 10 messages. So, essentially I think, your wish is already true :-) Alex. (Yes, tested pretty thoroughly in 10.0DP6 but I believe also true in earlier versions; I had to re-test this two days ago while playing with the recent benchmarking of groups vs cards). ___ 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
Re: resizeControl wishes...
Paul. “reSizeControl” is a message. What I mean by that is if you are already running under script control, why do you need to send such a message at all? Can’t your handler do whatever you needed to if the user did the actual resize action?

resizeControl wishes...
resizeControl is sent "only sent when the user resizes a control by dragging its handles. It is not sent if a handler changes the size of a control by changing its properties (width, height, and so on)." Does anyone else really really wish that resizeControl was set when the control's size is changed via script? I sure do! For example, I have cards with multiple groups of objects on them. Each of my groups (and sometimes sub-groups) have resizeControl handlers that position everything in the groups appropriately. I do this for portability. If I copy the group to somewhere else, the handler (resizeControl) that knows how everything is to be moved and resized goes with the copied group. My card script has a "resizeStack" handler that just sets the rects of the top level groups and dispatches resizeControl to each group on the card after changing its rect. I really wish I could eliminate these "dispatch" (or send) commands. I forget to include them some times, simple expecting (even though I know better) that if I change the size (rect) of a control with a "resizeControl" handler, that that resizeControl handler should execute! Anyone else wish that resizeControl would get executed if a control's size is changed by script? It just seems counter-intuitive that it does not. ___ 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
