Hello Alex,
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?
regards,
Usman

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
