Moving controls smoothly around the screen

Pete.


I am not understanding. Are there several objects (buttons and/or groups), but at least one group, under each button?


And there are a bunch of these "object stacks" vertically aligned, so there is a column of them?


I would have thought you would show and hide as needed, within each " object stack".



But you say:


I need to move all the objects underneath down to make room for the hidden group associated with the button to be displayed.



If you are moving these objects, where are they moving to? You don't mean they are moving from layer to layer, do you? 



You say you are using a "show" command to "move" the objects. If this is just how you are describing it, then why not just show or hide the objects in any particular "stack" by grouping them on the fly, if you need to, and applying the visual effect to the group. You would have to manage the members of the ad hoc group, but that should be straightforward.

I have a stack with a number of buttons and groups on
it,all vertically aligned.  The groups are initially hidden so the screen
looks like it has a series of buttons on it.

When a button is clicked, I need to move all the objects underneath down to
make room for the hidden group associated with the button to be displayed.

Also have the same situation (but in reverse) when a button is clicked and
its group is already visible.  In that case, I need to hide the group and
slide all the objects under it up to fill the gap.

I use the "show group ... with visual effect" command to smoothly reveal
the group (hide group... with visual effect to hide it) but I'm stuck on
how to move the other objects in an equally smooth way.  Ideally, I'd like
them to move in lock step with the group.

I've tried various forms of the move command  and settings of the lockMove
property but can't seem to get it to work, probably because I'm not
understanding all the options.  After the group is shown/hidden, the rest
of the objects just snap to their new positions rather than move smoothly.

It's almost like I need the move command to have a "with visual effect"
option.  I have a horrible feeling this is going to involve a bunch of
repeat loops to move objects around in small increments at specified
intervals but clinging to the hope the there might be anLC built-in way to
do it.
