Hi Alex,
Interesting, but it should be different :):
- the main purpose of the scrollbar is to show the position of the visible part within the
overall canvas. However, currently, the size of the scroll bar is constant, and thus it
does not solve the goal. To solve this, we need to be able to react to ROCamera bounds
change events.
- furthermore, when scrolling by clicking and dragging on the canvas, the scrollbars do
not get updated (even worse, the vertical one disappears).
- another characteristic of a scrollbar is to not be intrusive. We learnt that from Apple
that we actually not need a scrollbar when we have a good way to scroll. So, the bars
should be transparent and thinner.
Cheers,
Doru

I feel. Feel free to try:

| view els stack |
view := ROView new.
view add: ROElement sprite.
els := ROElement spritesFor: (1 to: 500).
els do: [ :el | el + ROLabel @ ROPopup ].
view addAll: (ROGridLayout on: els).
view @ RODraggable .
stack := ROViewStack new.
stack addView: view.
stack @ ROScrollbable.
stack open.

Hello,
How to we add horizontal and vertical scroll bars to a Roassal visualization. I browsed
through some examples but could not find one with these.
