I have a scrollable panel working (it didn't take long in the end). A
panel can now be much wider or higher than the available area, and the
user can scroll around using [Shift]F5, [Shift]F6, [Shift]F7, and
[Shift]F8. The user can also scroll the panel down to get a bigger
external view. Mouse clicks seem still to be working correctly.
To set the panel's (virtual) height and width, use the panel file's /w
and /h properties in a panel XML file; to set the initial x- and y-
offsets (untested), use the panel file's /x-offset and /y-offset
properties; to set the initial height of the external view (untested
and optional), use the panel file's /view-height property. Note that
none of these show up in the regular FGFS property manager.
Unfortunately, these patches will not affect your initialization
problems with the property manager -- I'm having a hard time tracking
them down because I cannot reproduce them.
I have also made some patches to main.cxx and views.cxx to do two
things:
1. Expand or shrink the external view as the panel moves up and down.
2. Set the window ratio correctly, so that we don't get an oval sun
and flat clouds when the panel is visible (the problem before was
integer division, so I added casts).
Unfortunately, the window ratio is not set properly at start-up --
there are too many dependencies, and I haven't figured that part out
yet. As soon as you hide and redisplay the panel or move it
vertically (i.e. force fgReshape to be called), you'll see the correct
ratio.
- /engines/engine0/rpm changed to read-only
- /engines/engine0/egt added (read-only)
- /controls/mixture added
- /controls/propellor-pitch added (not used for C172)
BFI:
- getEGT() added
- getMixture() and setMixture() added
- getPropAdvance() and setPropAdvance() added (= pitch)
- cleaned up reinit function a bit
- force reinit only when values are actually changed; for example,
setting the flight model to the current flight model will not cause
a reinit
LaRCSim:
- hook up mixture and pitch to FGControls (they were hard-coded
before)
- /engines/engine0/rpm changed to read-only
- /engines/engine0/egt added (read-only)
- /controls/mixture added
- /controls/propellor-pitch added (not used for C172)

LaRCSim:
- hook up mixture and pitch to FGControls (they were hard-coded
before)
and prop inertia and passed the timestep from LaRCsim in order to have
the engine rpm behaving according to the applied torque and the laws of
physics.
This set of changes cleans up my previous ones quite a bit:
[tony@valkyrie FlightGear]$ tar -ztf tp_changes.tgz
src/Controls/controls.cxx
src/Controls/controls.hxx
src/FDM/JSBsim.cxx
src/Main/fg_init.cxx
src/Main/options.cxx
src/Main/options.hxx
src/Joystick/joystick.cxx
controls.[ch]xx: removed the trimmed_throttle stuff. This undoes the
changes I submitted last time.
JSBsim.cxx: updates for the removal of the trimmed_throttle stuff
fg_init.cxx: removed the autothrottle logic. The autothrottle is now
off
by default.
options.[ch]xx: Sets trim_mode to false by default. It is enabled only
when --notrim is not used and JSBsim is the FDM.
joystick.cxx: Added logic for syncing the throttle lever. This is
only enabled when trim_mode is enabled. The way I
did it is, I hope, a good way of going about it.
I tested:
fgfs --fdm=larcsim
fgfs --fdm=jsb --aircraft=c172 --vc=100 --altitude=500
fgfs --notrim --fdm=jsb --aircraft=c172 --vc=100 --altitude=500
All work as intended, at least for me.
Make sure your joystick is calibrated and give:
fgfs --fdm=jsb --aircraft=c172 --vc=100 --altitude=500
a try, I think you just might be impressed.
I am. ;-)
