The `racket/gui' re-implementation has improved over the past two weeks. It's still not ready for everyday use or even bug reports, but it's getting closer. The most visible difference is that controls and canvases refresh and resize more cleanly. The least visible difference is that a complete memory-management strategy is in place (e.g., unused widgets are garbage-collected).
The code is still hosted here: http://github.com/mflatt/gr2 Beware that I occasionally pull with `--rebase' from the main Racket repository and push to gr2 with `--force'. Sam helpfully filled in a binding to the the Gtk file dialog. If anyone is interested in helping further, here's my current wish list: * Standard file dialogs under Cocoa. * Enabling a canvas to serve as an OpenGL context. * Implement `printer-dc%' along with platform-specific printer and print-setup dialogs. Some other things I'm still working on: * Display shortcut bindings in Gtk menus, get all keybindings working, and generally sort out the fine points of keyboard events. * Everything related to `cursor%'. * Make Cocoa `tab-panel%' look right in no-border mode (like in DrRacket's main window). * Sort out `register-collecting-blit', which is tough to reconcile both with implementing the binding in Racket and with a refresh model that effectively prohibits direct drawing onto the screen. * Smooth over the difference between platform-specific and platform-independent bitmap rendering. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
