Mostly necessary because SDL doesn't properly return mouse buttons X1/X2
on Linux/X11, see https://bugzilla.libsdl.org/show_bug.cgi?id=2310
Not sure if this is possible with Windows, DIMOFS_BUTTON7 seems to be
the highest constant there.
Also passing sdlevent.wheel.y directly as scroll delta
The d3bfg internal SE_CHAR events were documented as "evValue is an
ascii char", but are actually at least UTF-16, as returned by
Windows WM_CHAR events.
We now assume it's UTF-32 (UTF-16 has the same values mostly)
and the SDL backend now puts UTF-32 chars into SE_CHAR events.
In the Windows backend I make sure that no surrogate UTF-16 chars are
emitted + I added support for WM_UNICODE messages.
Now I can input Ümläuts intö the conßole window \o/
Sys_GetEvent()
* renamed res_none to no_more_events, because that's what the
caller assumes when getting that event
* don't return res_none on unhandled events, instead get the next event
until there is a handled event or no more events
(=> if -> while, return res_none -> continue)
* Mapping to Doom3 keynum handled differently for SDL1 vs SDL2, see below
For SDL2 we don't use SDL_KeyToDoom3Key on the keysym anymore, but map
the SDL2 scancode to Doom3/Direct-Input scancodes instead (the keynum_t
K_* constants are really used as scancodes!).
This mapping is done in sdl2_scancode_mappings.h scancodeToKeyNum[].
In sdl_events.cpp there are static SDLScanCodeToKeyNum() and
KeyNumToSDLScanCode() functions that use this scancodeToKeyNum[] array.
Sys_GetKeyName() now does something sensible for SDL2 by using
KeyNumToSDLScanCode()
This is also used to implement idKeyInput::LocalizedKeyName() for SDL-targets
(for SDL1.2 the behavior doesn't change much, though, as it doesn't have
consistent scancodes - Sys_GetKeyName() will just return NULL and
idKeyInput::LocalizedKeyName() will fall back to the old default)
turns out that both d3bfg and cegui use direct input scancode numbers
to represent keys internally.. now isn't that fucking convenient!
d3bfg was missing some, though, so I added them
strdup() and free() aren't really the right tool if the size of the
buffer is known anyway (and quite small, currently 32 chars)
while at it, I renamed s and s_pos to str and str_pos for better
readability
* Tested in Linux with both XBox360 wireless and Logitech F710 gamepads.
Should work with any XBox gamepad clone wired/wireless.
* Works well using SDL 1.2 or SDL 2.0
* SDL scan values are currently hard-coded. Note sure how to implement
remapping at the moment (config file, GUI, ...).
For some reason SDL.h (or headers included by it) need some
string functions (like strncmp) in inline-functions (that we
don't even use).
Str.h has #defines preventing their usage.. so #undef those in
the (few) sourcefiles that need SDL headers
All these files were almost identical, so there is no good reason to
have them twice..
and change CMakeLists.txt accordingly
(Not that this commit won't compile because some #includes are still
broken - will be fixed in the next one)
