Oh, I see.

Got it.

Thanks, Mark.

Thanks, guys.

All great solutions.

I think " the owner of " was the most ideal for my purposes.
That said, it didn't work perfectly with my nested groups. Strangely, the top group was acknowledged by just one of its two subgroups, and ignored by the other (which instead identified the current card ...

Is there any way I can tell what - if any - named group(s) a particular object/control is a member of?

Or, to use an alternative approach, is there any way I can list the member objects of a particular group?

Thanks, Mark.

That works well.

Good idea.

But, however the routine were implemented, I would still prefer for it to be called when the user selects Edit:Undo from the menus.

Surely selecting any menu item ought to trigger a system message that one could intercept?

Alternatively, does anyone know how I could modify the Edit ...

Well, I peek at the clipboard data - but I don't "mess around" with it beyond that. By convention, when you paste from the clipboard, the clipboard data remains unchanged so you might even paste again (a second, third or fourth copy - even if the original instruction had only been to "cut").

But ...

Thanks, Mark.

That's a bit remiss, don't you think?

It seems I CAN intercept the undoKey * - which, surely, is always Cmd-Z (or Ctrl+Z on Windows);

and it seems I can even intercept a message ( undoChanged ) when the action to be undone updates to some new action.

So why wouldn't Rev developers ...

I want to enable my user to drag from point A to point B and for this to draw a curved line with an arrowhead at the end.

But I can't figure out a quick way to do this.

It's simple to get Rev to draw an oval between points A and B.

Surely, if Rev can calculate an oval, then it should be able to ...

I have a facility that enables users to delete fields from my main stack, using the list in a palette:

on deleteKey
` get the value of the selectedLine
` cut field it of card 1 of stack "organiser 4"
` send mouseup to button "List Fields" of card 1 of stack "organiser 4" -- updates the field list ...

Thank you all. I will look up dialogData.

Thank you so much. I think that was exactly what I was after.

I had to set up OK and Cancel buttons along the following lines:

on mouseUp
global Clicked
put "OK" into Clicked
close this stack
end mouseUp

Once closed, the calling script resumes, and can glean information from the altered card ...

I'd like to use a stack as a sort of input dialog box.

There would be various fields and radio buttons in the "dialog" stack.

I'd like my script to pause for input, show the "dialog" window and allow the user to input data.

When the user hits an "OK" button, or the return key, I would like the ...

Actually, I have just discovered that, greyed-out buttons notwithstanding, I CAN actually change the object numbers/positions - by typing new values into the layer field of the "Size and Position" object Inspector.

I cannot type new values into the number field, for some reason (greyed out); but ...

I have a background group in a stack which contains - I hope - all the fields and buttons on the card (some twenty odd).

For some reason, I am no longer able to rearrange the tabbing order as I would wish. Any field, no matter what its number, will only allow me to "Send Forward" or "Send to Front ...
