Horray, this works! I'm now able to display content and it's nicely line-wrapped, etc. Only one problem: Now I have a ton of "editors" which were probably never meant to be used like this for hundreds of little "microblogs". ;) The main issue is that scrolling with all these editor canvases in place is super slow and really chews up CPU. (When I'm not scrolling, it seems fine.) I wonder if there are any obvious hacks I could perform? Caching things (is it possible to grab a bitmap of the current text editor's display content?), replacing the canvases with blank content when not being looked at, etc? -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
