Hi,

�

This seems correct to me: a transformMorph is the one which shift its contents (and reset the origin to its top left corner ?).

Not really. The contract of submorphBounds should be that it returns an absolute coordinate, as far as I understand.

In owner coordinates it says. (TransformMorph)

However, it effectively returns a 0@0 origin.

Why do you use a TransformMorph there?

It is used for example in ScrollPane. This means that if you embed a TextMorph inside a ScrollPane, you will have the same problem with completion:

scrollPane := ScrollPane new.
pasteUpMorph := PasteUpMorph new.
scrollPane scroller addMorph: pasteUpMorph.
scrollPane openInWindow top: 100; left: 100.

pasteUpMorph submorphBounds "(0@0) corner: (50@40)"

Yes.

What do you want to do about it? Rewrite a scroll pane in a different way? Or make sure that everything which creates over-morphs ask for global coordinates?

I guess this has also something to do with the glamour bug inside tabs, no?
