Hi all,
Today Peter Hutterer posted a preliminary feature list of Xinput 2. I have forwarded the email to here so that Vitaly and others can check it out and see if it offers what we need in Wine. If you have comments I would send them to the xorg list.
Regards, Roderick Colenbrander
--- Xorg mail --- Subject: [RFC] Preliminary XI 2 feature list
Following XDS, various notes, the discussions and preliminary executive decisions by me, here's a first draft of XI2 features. If you have anything to add, please speak up.
Time-line: I'd like to get it into server 1.6 but it doesn't look particularly likely. 7.5 is more likely.
- Compatibility with XI 1.x, although some requests will be deactivated or of limited functionality. - 16 bit device IDs - All events available as XGE events. - Event selection through event masks (instead or in addition to the event classes). i.e. the common cases of "select from all devices" and "select from all master devices" will be simplified. - Devices may have relative + absolute axes simultaneously, and change the mode on any of these axes at runtime. - Relative coordinates as a separate event. - 32 bit keycodes (reliant on XKB2) - ListInputDevices will include the currently attached Slave - Axis and button labelling through device properties. - subpixel resolution (from relative devices) available to clients. i.e. you get the data in screen coordinates, but with subpixel resolution available as fixed floating point. - no window access protocol, this will be thrown out. - dynamic device classes - device may add/remove classes at runtime. - aspect-ratio scaling of valuators.
Probable implementation details: - libXi: "namespacing": i.e. X<dosomething> will be XI<dosomething> - server-internal use of XGE events, XI 1.x events emulated when needed. - some standardisation on axis label Atom names. - Clients have to announce XI2 support, otherwise they will be treated as XI 1.x clients.
Once the feature discussion is complete, I'll get a protocol spec out.
Cheers, Peter _______________________________________________ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
