Hello,
Now you confirm that its the way to go, I'll improve the solution and will commit my changes in Roassal repo. I'll keep you updated with progress and questions :-).
cheers, usman

Look good!
A couple of comments:
- the size of scrollbar should depends on the size of the view
- the scrollbar seems "to escape" where its space. It leave the window
- When I drag the visualization from its background, the scrollbar seems
to move with the visualization itself
I think those are the most important points. I would be happy if you could continue your effort. This is important, many are asking for this.
Cheers, Alexandre

Hello,
Here is a proposition for scrollbars in Roassal. The idea is show
scrollbars only when the cursor goes in the blue region in the figure (colored blue for illustrated purpose only, otherwise it would be transparent). A test script is also attached. I built this on the implementation provided by Alex. As this is just a mock, there are still some points to be resolved (redrawing bars in case of window resize, dragging still makes disappear vertical bar). But these issues can be addressed once we know what is intended to be retained in Roassal.
Did you guys discuss on these lines or something completely different?
regards, Usman

I am sure that Alex can build the scrollbar inside Roassal :). We already discussed about how it should work, and I do not think it is that difficult.

alex I understand your concerns but without scrollbar this is not so great. So we will probably have to extend roassal in our corners.

Would it not be good to put classic pharo scrollbars (as was the
case with Mondrian, see the attached screenshot from a mondrian visualization) for Roassal visualizations?
This is not possible for several reasons:
- if I had Morphic scrollbar, then keeping Roassal dialect
independent will be harder
- I would like Roassal to be _really_ scalable in the future (my
goal is 1 000 000 nodes). Relying on Morphic for the scrolling may impede this goal.
I will try to come with an implementation for this soon.

Hi Usman,
I have been slow on this. Thanks for pushing! I will try to come with an implementation for next Sunday.
Cheers, Alexandre

Hi Alex,
Do you plan to evolve progress bars in Roassal in the direction
suggested by Doru?

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
