[Moose-dev] Re: adding scroll bars to Roassal Visualization

> 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.

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 >> >> >> On 5 Jun 2012, at 23:24, Alexandre Bergel wrote: >> >>> I started to work on it. Not perfect, but a good start I feel.
