| 27 <interface name="zwp_stylus_v1" version="1"> |
| 28 <description summary="extends wl_pointer with events for on-screen stylus"> |
| 29 Allows a wl_pointer to represent an on-screen stylus. The client can |
| 30 interpret the on-screen stylus like any other mouse device, and use |
| 31 this protocol to obtain detail information about the type of stylus, |
| 32 as well as the force and tilt of the tool. |
| 33 |
| 34 These events are to be fired by the server within the same frame as other |
| 35 wl_pointer events. |
| 36 |
| 37 Warning! The protocol described in this file is experimental and |
| 38 backward incompatible changes may be made. Backward compatible changes |
| 39 may be added together with the corresponding uinterface version bump. |
| 40 Backward incompatible changes are done by bumping the version number in |
| 41 the protocol and uinterface names and resetting the interface version. |
| 42 Once the protocol is to be declared stable, the 'z' prefix and the |
| 43 version number in the protocol and interface names are removed and the |
| 44 interface version number is reset. |
