Until now, the new qwaq startup was used only in command-line tools and
console applications where things like Ruamoko security and having a
hunk were not an issue. Now the start up code (qwaq-*.c) can specify
that Ruamoko is to be secured and provide a hunk on a per-thread basis,
and the thread data is passed into the progs code via a progs resource.
It now uses the advanced command line parsing used by qwaq-curses and
qwaq-cmd, but currently disables multi-threading (I don't want to deal
with threading in the engine just yet). The int file is -graphics
because qwaq-x11 is really just the X11 target, qwaq-win is built for
windows, but they use the same basic startup (I hope).
This is needed for cleaning up excess memsets when loading files because
Hunk_RawAllocName has nonnull on its hunk pointer (as the rest of the
hunk functions really should, but not just yet).
This is actually a better solution to the renderer directly accessing
client code than provided by 7e078c7f9c.
Essentially, V_RenderView should not have been calling R_RenderView, and
CL_UpdateScreen should have been calling V_RenderView directly. The
issue was that the renderers expected the world entity model to be valid
at all times. Now, R_RenderView checks the world entity model's validity
and immediately bails if it is not, and R_ClearState (which is called
whenever the client disconnects and thus no longer has a world to
render) clears the world entity model. Thus R_RenderView can (and is)
now called unconditionally from within the renderer, simplifying
renderer-specific variants.
This should be a much friendlier way of "grabbing" input, though I
suspect that using raw keyboard events will result in a keyboard grab,
which is part of the reason for wanting a friendly grab.
There does seem to be a problem with the mouse sneaking out of the
top-right and bottom-left corners. I currently suspect a bug in the X
server, but further investigation is needed.
This is the first step in the long-sought goal of allowing the window
size to change, but is required for passing on getting window position
and size information (though size is in viddef, it makes sense to pass
both together).
Right now, only raw pointer motion and button events are handled, and
the mouse escapes the window, and there are some issues with focus in
focus-follows-mouse environments. However, this should be a much nicer
setup than DGA.
This has smashed the keydest handling for many things, and bindings, but
seems to be a good start with the new input system: the console in
qw-client-x11 is usable (keyboard-only).
The button and axis values have been removed from the knum_t enum as
mouse events are separate from key events, and other button and axis
inputs will be handled separately.
keys.c has been disabled in the build as it is obsolute (thus much of
the breakage).
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 is the simplest fix for the curses/input initialization order
issue. The terminal io code should still be moved to its own file,
really, but I think it can wait.
As it is now a completely separate sub-system, there is a bit of trouble
with mouse handling in that curses must be initialized before input for
the mouse to work properly, but the basic scheme seems to be working
nicely. I suspect the solution to the init order issue is to make have
the curses sub-system initialize the terminal input driver, at least for
mouse input (ie, maybe just enable/disable mouse handing).
The queues in the curses resources struct have been cleaned up and the
threading support code (including for the queues (pipes, really)) has
been moved to its own file.
The input test app currently just prints the devices and the events as
they come in, but demonstrates the new input system working in a
separate thread (though it is currently in with the curses thread).
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).
For now, the functions check for a null hunk pointer and use the global
hunk (initialized via Memory_Init) if necessary. However, Hunk_Init is
available (and used by Memory_Init) to create a hunk from any arbitrary
memory block. So long as that block is 64-byte aligned, allocations
within the hunk will remain 64-byte aligned.
After seeing set_size and thinking it redundant (thought it returned the
capacity of the set until I checked), I realized set_count would be a
much better name (set_count (node->successors) in qfcc does make much
more sense).
qwaq-curses has its place, but its use for running vkgen was really a
placeholder because I didn't feel like sorting out the different
initialization requirements at the time. qwaq-cmd has the (currently
unnecessary) threading power of qwaq-curses, but doesn't include any UI
stuff and thus doesn't need curses. The work also paves the way for
qwaq-x11 to become a proper engine (though sorting out its init will be
taken care of later).
Fixes#15.
This refactors (as such) keys.c so that it no longer depends on console
or gib, and pulls keys out of video targets. The eventual plan is to
move all high-level general input handling into libQFinput, and probably
low-level (eg, /dev/input handling for joysticks etc on Linux).
Fixes#8
And fix an error in floatview.
The z-transform program is so I can test out my math and eventually
develop some hopefully interesting sound generators.
The editor now uses the vertical scrollbar for handling mouse wheel
scrolling, thus keeping the scrollbar in sync.
Scrollbar index can now cover the full range (not sure why I had that
-1), and the potential divide by zero is avoided properly.
Thumb-tab now positioned properly when the range is 0.
This gets all the basic cursor motion from my old editor working.
arrow keys: left/right/up/down char/line
home/end: beginning/end of line
page up/down
and ctrl versions where left/right are prev/next work, up/down skip over
indents, home/end are beginning/end of screen, and page up/down are
beginning/end of text.
The word boundaries are currently vary simple, just transitions from
alnum_ (as it was in my old editor and in Borland's editors), but the
basic logic is working.
Currently, home always moves the cursor to the very first column, but
I'm considering making it move the cursor to the first non-space
character of the line if it's not already there, otherwise to the first
column (ie, the cursor will toggle between the two positions if it's in
one of them).
