Ah, ok, just comparing now. I added this pdtk_canvas-getscroll to Pd- extended 0.42.5-2009-11-12. We currently have four to compare: Ico's, Pd, Pd-extended, and Pd-Gui-Rewrite.
- Pd-extended will correctly handle the scrollbars if you select some objects and move them with Shift-arrow, the other three do not (some better than others)
- when you select all and mouse drag components out of the current view, Pd-extended updates scrollbars immediately, Pd and Pd-devel update the scrollbars once you release the mouse, and Ico's gave me an error saying "Error: can't read "::scroll(.x6d5610)"
- when you resize the window, Pd-devel updates the scrollbars live, Pd- extended updates live with glitches, Pd updates on release, Ico's gave me an error saying "Error: can't read "::scroll(.x6d5610)"

- 0 0 coordinate-centric design IMHO does not make sense. From
historical perspective, old patches should still TTBOMK open just fine. Yet, if 0 0 approach is still imposed, it results in unintuitive behavior of scrollbars. e.g. try the following on 0.43 (or previous versions without the suggested patch):
create an object->create another object and slide it to the right until it goes outside the canvas area->a horizontal scrollbar will indicate there is more stuff to the right->scroll to the right and at this point you may find both of your objects (effectively your whole patch) within the canvas, yet the scrollbar will suggest there is something to the left when there isn't.
After testing this a bit more, here's a small correction. My implementation does pack everything to the right or the left depending upon where the whole canvas is located in respect to the 0 0 coord. This does not however affect older patches. That said, I still feel this is more desirable and ultimately can be further adjusted as necessary.
Best wishes,
Ico
I wanted to try this now that I have a moment, but I couldn't find the patch. Did you add it to the patch tracker?
