2011-10-13input: change pointer screen crossing behaviour for multiple ScreenRecsPeter Hutterer1-2/+3
miPointerSetPosition traditionally took coordinates on a per-screen basis, triggering a screen switch when these went out-of-bounds. For absolute devices, this prevented screen crossing in the negative x/y direction. This patch changes the event generation patch to handle screen coordinates in a desktop range (i.e. all screens together). Screen switches are triggered when these coordinates are not on the current screen. This unifies the pointer behaviour of single ScreenRec multihead and multiple ScreenRecs multihead in that the cursor by default moves about the whole screen rather than be confined to one single screen. The transformation matrix may then be used to actually confine the cursor to the screen again. Note: fill_pointer_events has to deal with several different coordinate systems. Make sure you read the comment before trying to understand the code. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

2011-09-30Input: Add smooth-scrolling support to GetPointerEventsPeter Hutterer2-0/+43
For scroll wheel support, we used to send buttons 4/5 and 6/7 for horizontal/vertical positive/negative scroll events. For touchpads, we really want more fine-grained scroll values. GetPointerEvents now accepts both old-school scroll button presses, and new-style scroll axis events, while emitting both types of events to support both old and new clients. This works with the new XIScrollClass to mark axes as scrolling axes. Drivers mark any valuators that send scroll events with SetScrollValuator. (Currently missing: the XIDeviceChangeEvent being sent when a driver changes a scroll axis at run-time. This can be added later.) Note: the SCROLL_TYPE enums are intentionally different values to the XI2 proto values to avoid copy/overlapping range bugs.

To be used for smooth scrolling with future driver APIs, replacing Rel Vert Wheel and Rel Horiz Wheel axes, which have not been used in any open driver to date.
