google (though as time passes, it's more and more spotty in its coverage) I hadn't really thought about gpm in particular, but wheel mice are doable with the extension I added a few years ago, and have tested in xterm (which is a binary change). That part is something that Daniel Baumann is steering toward in ncurses updates. For gpm specifically - that would still require some change (but doesn't require a whole new version of ncurses). Someone a few months ago stated that there's some patch (or configuration) where gpm would deliver button 4/5 events sort of like xterm, but looking at the gpm.h header, the only comments regarding wheel mice say it's not clear: /*....................................... Cfg buttons */ /* Each button has one bit in the 16 bit buttons field. * Mouse movement and wheel movement are not associated with a button * i.e. buttons=GPM_B_NONE in these cases * (except for ms3 mouse, for reasons unknown?) * The middle button if pressed down (or clicked) is independent of * the wheel "device" which it happens to be associated with * The use of GPM_B_UP/DOWN with ms3 is unclear. Maybe the wheel * could be rolled forward then backward * and this would generate a 'click' event on 'button 5' GPM_B_UP, * but really the expected behaviour of wheel is movement, typically * used for jump scrolling or for jumping between fields on a form. */ #define GPM_B_DOWN 32 #define GPM_B_UP 16 #define GPM_B_FOURTH 8 #define GPM_B_LEFT 4 #define GPM_B_MIDDLE 2 #define GPM_B_RIGHT 1 #define GPM_B_NONE 0 (since gpm's documentation is its source code...) -- Thomas E.
