touchpad: Drop the scroll direction lock, increase threshold instead

The direction lock was intended to avoid erroneous horizontal scroll events
when scrolling vertically (and vice versa). Some testing on my touchpad here
shows that it is too easy to accidentally lock the direction when no lock is
intended (e.g. moving around an image). And quite hard to figure out what a
pure vertical gesture is.

I get movements from 90 degrees to 70 degrees for something my brain would
consider vertical scrolling. Depending on the hand position, the fingers
actually perform a slight curve, not a straight line.

Hence - drop the direction lock, but increase the threshold a little. It
doesn't totally avoid horizontal scroll events but keeps them minimal.

one for usec/nanosec. So at 32 bits our ms containing integer will wrap
in 50 days, while the kernels seconds storing integer lasts a lot longer.
So when we wrap our ms timestamps, we will be programming the timer-fds
with a seconds value in the past.

So change all our internal timestamps to uint64_t to avoid the wrapping
when programming the timer-fds. Note that we move from 64-bit timestamps to
32-bit timestamps when calling the foo_notify_bar functions from
libinput-private.h. Having 64 bit timestamps has no use past this point,
since the wayland input protocol uses 32 bit timestamps (and clients will
have to deal with wrapping).

10 years agotouchpad: Add clickpad-style software buttons
Peter Hutterer [Thu, 27 Mar 2014 23:44:11 +0000 (09:44 +1000)]
touchpad: Add clickpad-style software buttons

Almost all non Apple touchpads have visible markings for software button areas,
so limit clickfinger behavior to Apple clickpads, and implement software button
areas for others.

This is a slightly fancier implementation than the simplest model and ported
over from libtouchpad. It implements a state machine for the software buttons
with left and right buttons currently implemented. Buttons are oriented
left-to-right, in a horizontal bar. No random button placement allowed.

In general, the procedure is:
- if a finger sets down in the left button area, a click is a left click
- if a finger sets down in the right button area, a click is a right click
- if a finger leaves the button area, a click is a left click
- if a finger starts outside the button area, a click is a left click

Two timeouts are used to handle buttons more smoothly:
- if a finger sets down in a button area but "immediately" moves over
  to a different area, that area takes effect on a click.
- if a finger leaves a button area and "immediately" clicks or moves back into
  the area, the button still takes effect on a click.
- if a finger changes between areas and stays there for a timeout, that area
  takes effect on a click.

Note the button area states are named BOTTOM_foo to make it easier to later
add support for a top button area such as can be found on the Thinkpad [2-5]40
series.

Introduce seat wide button and key count API

Compositors will need to keep provide virtual devices of supported
generic device types (pointer, keyboard, touch etc). Events from each
device capable of a certain device type abstraction should be combined
as if it was only one device.

For key and button events this means counting presses of every key or
button. With this patch, libinput provides two new API for doing just
this; libinput_event_pointer_get_seat_button_count() and
libinput_event_keyboard_get_seat_key_count().

With these functions, a compositor can sort out what key or button events
that should be ignored for a virtual device. This could for example
look like:

event = libinput_get_event(libinput);
switch (libinput_event_get_type(event)) {
...
case LIBINPUT_EVENT_POINTER_BUTTON:
device = libinput_event_get_device(event);
seat = libinput_event_get_seat(device);
pevent = libinput_event_get_pointer_event(event);

if (libinput_event_pointer_get_button_state(pevent) &&
    libinput_event_pointer_get_seat_button_count(pevent) == 1)
notify_pointer_button_press(seat);
else if (libinput_event_pointer_get_button_state(pevent) &&
 libinput_event_pointer_get_seat_button_count(pevent) == 0)
