Hot-plug support is done via "connections" (not sure I'm happy with the
name) that provide a user specifiable name to input devices. The
connections record the device name (eg, "6d spacemouse") and id (usually
usb path for evdev devices, but may be the device unique id if
available) and whether automatic reconnection should match just the
device name or both device name and id (prevents problems with changing
the device connected to the one usb port).
Input Mapping Tables are still at the core as they are a good concept,
however they include both axis and button mappings, and the size is not
hard-coded, but dependent on the known devices. Not much actually works
yet (nq segfaults when a key is pressed).
For drivers that support it. Polling is still supported and forces the
select timeout to 0 if any driver requires polling. For now, the default
timeout when all drivers use select is 10ms.
I had forgotten that _size was the number of rows in the map, not the
number of objects (1024 objects per row). This fixes the missed device
removal messages. And probably a slew of other bugs I'd yet to encounter
:P
This includes device add and remove events, and axis and buttons for
evdev. Will need to sort out X11 input later, but next is getting qwaq
responding.
The common input code (input outer loop and event handling) has been
moved into libQFinput, and modified to have the concept of input drivers
that are registered by the appropriate system-level code (x11, win,
etc).
As well, my evdev input library code (with hotplug support) has been
added, but is not yet fully functional. However, the idea is that it
will be available on all systems that support evdev (Linux, and from
what I've read, FreeBSD).
