And use it in preference to the crusty old XSetScreenSaver API. This
should work on modern systems (though might need to support the dbus
method too, but that can wait).
Some of them were actual leaks, but tracking memory should be a lot
easier now. However, there's a lot of room for optimization of
allocations (eg, recylcling of hierarchies. There is now 1 active
allocation (according to tracy) when nq exits: Qgetline's string buffer
(I think an api change is in order).
This relies on my fork of tracy: https://github.com/taniwha/tracy
on the wip-c-vulkan branch. Everything is still rather flaky though.
This necessitated the jump to vulkan 1.2 as a requirement.
This fixes the weird slug when running nq on windows. It turns out it
was the "friendly neighbor" sleep code activating due to bitrot. In
addition, there are cvars for enabling unfocused sleep (defaults off)
and disabling minimized sleep (defaults on).
A lot is broken, especially direct input, but things are working. Better
yet, it seems the X11 and Windows key bindings are at least mostly
compatible.
The event handling changes take care of VagueLobster's segfaults on
startup for all renderers (vulkan will still be iffy depending on his
hardware: it dies on my GTX 965 M, probably due to memory and QF's
shadows). One nice side effect is it takes care of the broken CD audio
event handling (does anyone even care, though?).
This seems to be more for legacy X11 (ie, without fixes etc), but
fullscreen really shouldn't affect grabbing directly (rather, it should
be up to the client whether grabbing (and thus warping) is enabled at
all.
It's currently very simplistic (visible, not visible), but it gets
things started for making QF more usable in a windowed environment (not
having a visible cursor was fine in DOS, or when full screen, but not
when windowed (and not actively playing).
I never liked it, but with C2x coming out, it's best to handle bools
properly. I haven't gone through all the uses of int as bool (I'll leave
that for fixing when I encounter them), but this gets QF working with
both c2x (really, gnu2x because of raw strings).
It seems that the mouse escaping the barriers requires some combination
of hitting two at once, and holding your mouth just right (something
about sliding the mouse up and down one barrier near the other).
However, sending the mouse back to the center of the screen when it
touches a barrier makes such sliding impossible.
This seems to fix#38
I obviously need a better way to test legacy code because the fix for
unsigned-int behavior with clang broke mouse warping when using
XGrabPointer instead of XInput2's XIGrabEnter.
Currently only for gl/glsl/vulkan. However, rather than futzing with
con_width and con_height (and trying to guess good values), con_scale
(currently an integer) gives consistent pixel scaling regardless of
window size.
A listener is used instead of (really, as well as) ie_app_window events
because systems that need to know about windows sizes may not have
anything to do with input and the event system.
This breaks console scaling for now (con_width and con_height are gone),
but is a major step towards window resize support as console stuff
should never have been in viddef_t in the first place.
The client screen init code now sets up a screen view (actually the
renderer's scr_view) that is passed to the client console so it can know
the size of the screen. The same view is used by the status bar code.
Also, the ram/cache/paused icon drawing is moved into the client screen
update code. A bit of duplication, but I do plan on merging that
eventually.
The misinterpretations were due to either the cvar not being accessed
directly by the engine, but via only the callback, or the cvars were
accesssed only by progs (in which case, they should be float). The
remainder are a potential enum (hud gravity) and a "too hard basket"
(rcon password: need to figure out how I want to handle secret strings).
This is an extremely extensive patch as it hits every cvar, and every
usage of the cvars. Cvars no longer store the value they control,
instead, they use a cexpr value object to reference the value and
specify the value's type (currently, a null type is used for strings).
Non-string cvars are passed through cexpr, allowing expressions in the
cvars' settings. Also, cvars have returned to an enhanced version of the
original (id quake) registration scheme.
As a minor benefit, relevant code having direct access to the
cvar-controlled variables is probably a slight optimization as it
removed a pointer dereference, and the variables can be located for data
locality.
The static cvar descriptors are made private as an additional safety
layer, though there's nothing stopping external modification via
Cvar_FindVar (which is needed for adding listeners).
While not used yet (partly due to working out the design), cvars can
have a validation function.
Registering a cvar allows a primary listener (and its data) to be
specified: it will always be called first when the cvar is modified. The
combination of proper listeners and direct access to the controlled
variable greatly simplifies the more complex cvar interactions as much
less null checking is required, and there's no need for one cvar's
callback to call another's.
nq-x11 is known to work at least well enough for the demos. More testing
will come.
