Well, I got signals to work on the first pass, minus the stupid typo that kept it from compiling at all. I'm sure something is #%!＠!ing stupid in it, but you can now attach lisp callbacks to GTK widgets, and they are done appropriately. If anyone wants to play around with it, please check out the latest CVS version. This test app should get you going. Another sick & twisted thing you might want to try is using: (setq box (frame-property (selected-frame) 'container-widget)) (setq widget (... muck with other widgets here ...)) (gtk-box-pack-start box widget nil t 5) (gtk-widget-show-all widget) That should stick whatever widgets you want at the top of the screen. I think it is doable to implement menus and toolbars using this instead of C code. There are a few functions that are not currently implemented... I'm not sure how to deal with functions that return things via pointers (some functions in GTK even return SINGLE values (integers even!) like this - lame!) I'm going to take a look at guile-gtk to see how they fixed that, but they have taken a fundamentally different approach and have a defs file that generates gobs of C code that you then compile, instead of calling the functions from the DLL directly. hrm. -Bill P.
