<alex-weej> seb128: ok so re https://bugs.launchpad.net/ubuntu/+source/gtk+2.0/+bug/223170 basically i figure gtk has support for mouse scrolling via interpreting buttons 4 and 5 as "scroll up" and "scroll down" instructions which are the discrete movements we already have which are quite large i'm thinking gtk AND xorg-input-synaptics need support for delta-based scrolling <seb128> ah ok, I've no idea about that <alex-weej> so synaptics needs to generate a hypothetical "scroll dx=16,dy=23" event kind of thing and gtk needs to interpret it <seb128> for me mouse cursor movements are purely an xorg thing <alex-weej> yeah cursor movements are but scrolling is different right? <seb128> I don't use a trackpad and I guess I don't understand the feature request <alex-weej> oh ok <seb128> well, scrolling is just a reaction to xorg events no? <alex-weej> yeah <seb128> so for me what you want there is xorg to react differently to some action that will impact on events generated and on how gtk will react no? I'm not sure what gtk hacks you want there <alex-weej> the code that runs when i scroll a window some amount is in gtk, not xorg, right? <seb128> right but this code doesn't know what a trackpad is it just reacts to xorg events no? <alex-weej> so if xorg is firing these new fancy scroll dx=15,dy=-23 events 25 times a second <alex-weej> gtk needs to deal with it <alex-weej> seb128: i think, i mean i have no clue. my choice of gtk and synaptics as tasks was just an educated guess bryce: maybe you can add some info? <seb128> alex-weej: ok, so as said I don't know better about this so we are just both doing educated guess ;-) <alex-weej> ok, well i'll copy this chat onto the bug if that's OK and chase up some more X/GTK people <seb128> alex-weej: might be better to take than upstream directly, maybe there is somebody reading bugzilla and knowing better ;-) alex-weej: sure <alex-weej> seb128: thing is, it needs cooperation with xorg stuff so taking it to either X or GTK independently is gonna be pain
