input.cxx allocates memory for js->getNumAxes() axes and for jsCaps.wNumButtons
or MAX_JOYSTICK_BUTTONS buttons per joystick. But it doesn't check if some
xml config defines bindings for more axes/buttons, in which case it writes
to unallocated memory and causes crashes. This is a real world example:
sidewinder-force-feed-pro.xml defines 7 axes, but only newer versions of
this js do actually have that many. Older ones (-> gameport) don't. The patch
drops unused and unusable bindings.
motion.
- Track a timeout value so we can optionally hide the mouse pointer after
some user specified timeout period.
- in doMouseMotion() always update m.x and m.y even if we return early because
pui wanted the event. Without this, we can't reliably detect motion vs.
inactivity.
- in _update_mouse() add a dt parameter so we can decriment the timeout value
in "real" time.
- in _update_mouse() optionally hide the mouse pointer if m.timeout goes to
zero. Restore the pointer (and the timeout counter) if the mouse is moved.
anymore. Instead Frederic Bouvier suggests to add a <number> tag to
the axis definition which accepts values for <windows> and <unix>
for now but which can be extended later on:
<axis>
<desc>Rudder</desc>
<number>
<unix>2</unix>
<windows>3</windows>
</number>
<binding>
<command>property-scale</command>
<property>/controls/flight/rudder</property>
<offset type="double">0.0</offset>
<factor type="double">1.0</factor>
<power type="double">2.0</power>
</binding>
</axis>
command bindings accessible from XML. This still probably isn't a final
solution (which would drive the HUD from propery values), but it's a step
in the right direction anyway.
the keyboard modifiers outside of a key event handler, so adding the
fgGetKeyModifiers() call to doMouseMotion was broken. The user could
see "phantom" modifier keys.
to handlers which might want to assign it to a SGPropertyNode_ptr for
reference counting (Nasal does, for instance, to prevent garbage
collector interactions). If that smart pointer is then destroyed,
that will free this object while it is still live.
Simply use a SGPropertyNode_ptr here; the code ends up smaller as a
bonus, since FGBinding no longer has to deallocation for _arg.
Frederic Bouvier:
First, MSVC 7 bombs when a value greater than 255 is passed to
issomething(), so I copy k to a char (unsigned ) kc before calling
them.
Second, with my french keyboard, and I thing this is the same for
a great number of countries, some characters from the regular ASCII
set can only be get with ALt Gr that appears to be CTRL+ALT.
Especially, I can't select the second engine because '@' is
AltGr+'' nor all because '~' is AltGr+'' (and I have to hit space
after otherwise I can get or that are not used in french) and
FG try to cope with the modifiers.
So, currently, we have to mask out CTRL and ALT modifiers when they
are together. The current bingings don't allow 2 simultaneous to
be declared so it shouldn't break anything.
This patch adds an "interval-sec" property which allows fixing an interval in seconds (or fraction of seconds) for the repeats for emulated axis controls (digital hats) on joysticks.
scene management code and organizing it within simgear. My strategy is
to identify the code I want to move, and break it's direct flightgear
dependencies. Then it will be free to move over into the simgear package.
- Moved some property specific code into simgear/props/
- Split out the condition code from fgfs/src/Main/fg_props and put it
in it's own source file in simgear/props/
- Created a scene subdirectory for scenery, model, and material property
related code.
- Moved location.[ch]xx into simgear/scene/model/
- The location and condition code had dependencies on flightgear's global
state (all the globals-> stuff, the flightgear property tree, etc.) SimGear
code can't depend on it so that data has to be passed as parameters to the
functions/methods/constructors.
- This need to pass data as function parameters had a dramatic cascading
effect throughout the FlightGear code.
menubar. This one allows regular command bindings, with the
(temporary) condition that every menu item must have a unique text
label. The new menubar is disabled by default; to enable it,
configure --with-new-menubar.
Some more cmall changes to the SimGear header files and removed the
SG_HAVE_NATIVE_SGI_COMPILERS dependancies from FlightGear.
I've added a seperate JSBSim patch for the JSBSim source tree.
Indeed, there was no check for panel visibility in the input code. I
guess we've never noticed because nothing was fighting for the same
real estate in the past. This one-liner appears to fix the problem.
