Hi!
Just to share our latest feature. We have implemented a simple mechanism in Roassal to prevent the environment to be sluggish with many elements.
The class RTCache has the effect to remove the elements from a view, create a bitmap from them, and add the bitmap to the view. Simple and effective. Consider the following script:
-=-=—=-=-=—=-=-=—=-=-=—=-=-=—= v := RTView new. v @ RTDraggableView.
colors := ColorPalette qualitative colors: 8 scheme:'Set1'.
elements := (RTEllipse new color: [ :aValue | colors atRandom alpha: 0.01 ]; size: #yourself) elementsOn: ((1 to: 500000) collect: [ :vv | 10 atRandom + 5 ]). elements do: [ :e | e translateTo: 500 atRandom @ 500 atRandom ]. v addAll: elements.
RTCache new cacheView: v. v -=-=—=-=-=—=-=-=—=-=-=—=-=-=—=
Without the line "RTCache new cacheView: v.” Pharo would be completely unresponsive. 500 000 elements is quite a lot.
The drawback is that all interaction with the elements are lost. I have some idea on how to add them back. We will work on this in future work.
Cheers, Alexandre
Clever! I'll be waiting for your idea on how to bring interaction back... I imagine something like coordinates on the bitmap to get the back elements as object again... Anyway surely will be an interesting solution, like this one.
Cheers,

I mean the one you are propossing with RTCache, not the one I just told :-P

Yes, very nice!
This is opening doors...
