As the Wx roadmap points out, all major goals for the next big release are met. They write: "We hope to make 3.0 in the first half of 2010.". Yes, Wx development is slow (meaning conservative) but why wait for so long?
For the Perl world Wxwidgets 3.0 could have some impact. The unification of several codebases speeds up development and Wx, already mature and feature-rich could improve faster to something that enables professional large WxPerl apps. Something I've been advocating for years.
I hope it improves especially in following parts: writeable XRC, more consistent AuiNotebook (see my last post), native filebrowser as a an integrated widget (not a dialog), improving WxHTML, simpler API and more powerful tree control, easier access to the accelerator table. I like it very much that Wx people care about details and gradually improve to remove all the itches sooner or later and there are lot more corners to sweep. But i have the feeling that some larger things are still missing. When i have some ideas about that i will post it.
