Calls to updateValues can cause nested calls invalidating
the char* passed as argument, if retrieved from a
SGPropertyNode.
Probably SGPropertyNode should also be modified to return
a std::string instead of a pointer to an internal buffer.
- no dependency on libJpeg or Simgear
- no duplicate rendering of the scene (uses a draw callback)
- supports other image types, eg PNG
- threaded so doesn't block the main loop ever
By Gijs with additions by James. Menubar is disabled at present
since it's not usable and potentially inferior to other solutions,
but committing the code so it doesn't rot.
Restarting the GUI could cause Cocoa menus to misbehave, due to
destruction behaviour of SGBinding. Use new clear() helper in the
short term to work around this.
In threaded OSG drawing, MapWidget::draw runs in the render
thread context, but touches lots of main thread state. Move most of the
work to an update() helper run on the main thread instead, so draw()
mostly makes pure GL calls.
(This is a fix for 3.0, the real solution is to migrate to a
Canvas-based map and GUI)
Write PID file to FG_HOME, use this to detect multiple launches.
When this situation is detected, set a marker property and place various
objects into read-only mode, such as the NavCache and TerraSync.
PID file is created using open+unlink semantics on POSIX, and
DELETE_ON_CLOSE on Windows, so it will be removed when fgfs exits,
even if killed or crashes.
This allows us to display a platform-native dialog for problems
which occur early in startup (before we can show a PUI/Canvas dialog).
In particular this improves feedback where FG_HOME, FG_DATA or
aircraft selection is wrong, all of which happen very early in startup.
Adding a spherical projection mode which will work at the poles and
+180/-180 line correctly. Not yet enabled since it has other issues to
be addressed.
Ensure all FGPositioned related functions return SGSharedPtr
instead of raw pointers to allow automatic conversion to
nasal ghosts without custom helper functions.
This adds the framework for platform cursor implementations; Windows and X11 to be done.
It also extend the mouse-input code to generate hover events suitable for driving tooltips.
Note there should be no visible functionality change from this commit, since everything
is inactive until fgdata changes are made.
This was a bogus concept, either runways have a reciprocal or not (if singled-ended), really this was simply exposing an artefact of the apt.dat encoding. Change to an API which gives what is actually wanted - the ability to extract an airport's runways without any reciprocals included.
Add a puaListBox which can show the contents of a log-buffer. Currently only two buffer sources are supported more to follow (and the dialog XML updates).
As an opt-in API, allow clients to request partial results, with a time-bounded cutoff. Use this to keep the MapWidget responsive even when many airports are being added to the cache (e.g., zooming out or panning rapidly when zoomed out)
Record the historical flight-path (by default, since last takeoff). Optionally display the flight-path in the map; other visualisations (e.g., an 'in-world' view) could also be created. Nasal API to follow so Canvas-map or FMS can show the same data.
Altitude and attitude (Euler angles) are currently recorded but not used anywhere.
If the size of a Canvas changes also the texture id
changes. We now retrieve the texture id for the CanvasWidget
every frame to ensure it uses the latest texture instance.
Was only cleaning up the PUI menubar, not old bindings / names. This led to duplicate bindings, each time the GUI was reset, which can happen for various reasons.
puObject only provides float, not double, which causes precision/rounding
issues with some numerical values (try "114.2").
Work around: obtain string value, and manually convert with proper double
precision.
Cache the parsed navigation and airport data in a binary file to reduce
startup times and memory consumption (since only referenced FGPositioned
elements are held in memory).
Data will be reimported when the mod-time of any input file is changed.
If a global file is changed (nav.dat, awy.dat, apt.dat, etc), the cache
will be completely rebuilt, which takes approximately 30 seconds on
moderate hardware. (Future work may reduce this).
so package builders don't need local patches.
Also, instead of hardcoded firefox, use "xdg-open" or "sensible-browser"

(Not affecting Mac/Win which are hard-coded anyway).
- Refactor and unify common functionality of canvas::Window and
canvas::Image
- Make canvas::Image actually work
- Allow using canvases inside canvas::Image
* Use new canvas:// "protocol" to allow using canvases in
place of images
- Prepare for categorizing canvases:
* Move canvases to /canvas/by-index
* Later support linking to other nodes in subbranches of
/canvas
- Allow hiding objects
- Use UTF-8 encoding for text elements
- Add paramter max-width to text elements
- Support stroke-linecap for path elements
- Fix mouse coords
- Set better mipmap filter
Convert the route-manager to use a flight-plan internally, and expose
flightplan, leg and procedure data to Nasal. Move the Level-D parser
into its own file.
Adapt FGPUIMenuBar to use new Locale module.
Adds support for separate "key" property for menu items, so keyboard hints
are no longer part of the item's label (and do not need to be part of the
translated text resources).
Copies HELVETICA_12 from PLIB to FG, adding some more chars needed for
Latin1/ISO-8859-1 (West European languages).
(SANS_12B and HELVETICA_14 also support Latin1, but not the other default
PLIB fonts).
Replace deprecated "old-help-dialog" command with generic "open-browser".
Can also be used to add links to aircraft manuals in the menubar (local
file or http) , i.e.
<binding>
<command>open-browser</command>
<path>Aircraft/ogeL/FlightManual.html</path>
</binding>
Make sure actual snap shot is executed in graphics context.
(Revert the revert :) - since the basic issue in simgear is solved now)
(patch requires simgear+fgdata update!)
Panning feature looked broken to some users since auto-center is enabled
by default which blocks panning. center-on-aircraft is now disabled
automatically when view is panned.
_dialog_props holds SGSharedPtrs (pointers managed by reference counters).
Explicitly casting the object to an unmanaged SGPropertyNode* and deleting it
may cause heap corruption, since the following assignment "_dialog_props[..] = ..."
also tries to delete the (already deleted) object.
Supports various new editing features, including dragging to re-order, and
+/- keys to adjust the target altitude for a waypoint. Also displays some
additional information, and will display *even* more once I land airways/
SID/STAR support.
Guard against invalid font names in panel XML files, and make font name
comparisons case-insensitive so that 'helvetica', 'Helvetica' or 'HELVETICA'
work as expected.
Patches for configure.ac and Makefile.am files in FG/SG so Mac developers can build these in a unix way.
These also enables Mac developers to choose either PLIB framework or PLIB static libs.
This can be used to validate atomic branches after individual members
have been changed.
(This is useful no matter how the discussion on aggregate property types
ends, and not meant to enforce/accelerate a decision.)
Can't reproduce the problem that r1.103 meant to fix, but it
caused another problem: MMB dragging events weren't passed,
so e.g. power lever control in the bo105 stopped working.

via style definition, but it's very rarely used and a change now
is probably not worth it as we'll probably switch to osgWidget,
anyway.)
displayed garbage in the title line if one left a directory. Jester
spent a lot of time finding the cause: a bug that must have been
there since ... forever: fgfs reported to PUI the string addresses
as returned by SGPropertyNode::getStringValue() without considering
that this address isn't valid after the next write access to that
node! It's almost a miracle that it worked so well for so long,
despite that issue. (I also used to opportunity for some more
cleanup -- so I'm to blame for any newly introduced bugs, and
also for reverting some of Jester's cleanups. :-)
CameraGroup supports cameras opened in different windows or in the
same window, with flexible view and perspective specification.
Clean up mouse click handling via osgViewer. Don't let any camera
"have focus;" this forces events to be reported in window coordinates
and simplifies life. Don't use the osgViewer::View::requestWarpPointer
method; instead use our own code which only deals with window
coordinates.
Make glut and sdl versions work with CameraGroup too.
- this exposed a bizarre issue on Mac where dragging in <AGL/agl.h> in
extensions.hxx was pulling in all of Carbon to the global namespace
- very scary. As a result, I now need to explicitly include CoreFoundation
in fg_init.cxx.
- change SG_USING_STD(x) to using std::x
SimGear change. It changes all the SG_xxxx to be the 'real' includes, and gets
rid of many #ifdef SG_HAVE_STD_INCLUDES. As an added bonus, rather than
replacing 'SG_USING_NAMESPACE(std)' with 'using namespace std', I just fixed
the small number of places to use std:: explicitly. So we're no longer polluting
the global namespace with the entire contents of std, in many cases.
There is one more 'mechanical' change to come - getting rid of SG_USING_STD(X),
but I want to keep that separate from everything else. (There's another
mechnical change, replacing <math.h> with <cmath> and so on *everywhere*, but
one step at a time)
PLETE_FUNCTIONAL from SimGear and FlightGear.
As a result, SG_HAVE_STD_INCLUDES is now *always* set, so I will get the boring
fixes for that done, but separately. I'm still auditing the other things in comp
ilers.h - there's a lot that can die now BORLAND is gone.
- drop unused parts (MouseQuat/GuiQuat)
- move "old-reinit-dialog" fgcommand to fg_command.cxx under new name
"reset" for now. (May later get merged with fgcommand "reinit".)
- move reInit() to fg_init.cxx: This was used by Shift-Esc and
Menu->File-Reset (via fgcommand "old-reinit-dialog"). We have already
a similar function fgReInitSubsystems() in fg_init.cxx, so these two
functions will probably get merged later.)
After the changes that moved the GUI and HUD to a slave camera, the
texture-based fonts wouldn't display. The main fixes here are making
sure that the TXF textures are all loaded into the font cache early,
and explicitly setting the active texture unit in the GUI / HUD
drawImplementation.
Switch to defining PU_USE_NONE and providing our own callback
functions to pui for "get window" and "get window size." A new
WindowSystemAdapter class assigns ID numbers to windows for the
purpose of identifying them to plib; the window size can be extracted
from the osg::GraphicsContext class in all the different
implementations (osgViewer, glut, sdl).
Implement a GraphicsContextOperation that runs code in a particular
graphics context, perhaps in another thread, and provides an
isFinished() method to test if the operation has finished. This allows
us to initialize plib PUI properly if there are multiple graphics
contexts without using fgMakeCurrent(). fgMakeCurrent() can't work in
multi-threaded OSG configurations.
Eliminate fgMakeCurrent() and all its uses, either by using
GraphicsContextOperation or by seeing that it is not necessary.
Attach the GUI camera as a slave camera.
Don't manipulate the OSG state in the drawImplementation() functions
for SGHUDAndPanelDrawable and SGPuDrawable; it's not needed.
- it's unused
- it's hardcoded (we already got rid of all other hardcoded dialogs)
- we'll have to consider switching to osgWidget, which is planned to
get imported into osg. It's unlikely that we add *more* of PLIB
in the meantime.

show "secret" values, that is: values of nodes with children. These
can be used like all normal (leaf) properties, but their values were
until now only shown in writeProperties() dumps. Also show the
number of attached listeners. Example: foo = 'bar' (string, AU, L3).
dialog.cxx: add warning message for broken <format>s; cosmetics

This allows to just write <hrule/> instead of <hrule><dummy/></hrule>.

SGPropertyNode to guarded ones. This is also done for JSBSim/JSBSim.hxx,
for which JSB had given explicit permission a while ago. I postponed that
back then, but now is the time.
there's a bug that I had copied: update() checks each list node: if it
has no children, then a listener is attached. Later, when freeing the
children list, it assumed again that each node without children would
have a listener attached. This caused a crash when a node had children
before, but lost them in the meantime. Now we tried to remove a listener
where there never was one.
*many* years, so the property browser always leaked memory. I activated
this line in property_list.cxx and ... got a crash right there. So this
was the reason for it being commented out? Doing the same for now, until
I know the exact reason and can really fix it.
- backport submissions for plib 1.8.5:
* set slider size correctly
* remove slider/arrow when all entries fit into the view
* don't allow to scroll off the list
Unfortunately, there's no simple way to distinguish them. plib has no
user defined widget classes, and getTypeString() -- which could be used
for that -- isn't virtual. Sigh. I'll discuss the problem on the plib list.
For now I can only offer an ugly workaround. (Don't look closely!)
from plib's file-picker, where it made some sense to keep the current path as
string, and to chop off elements when leaving a dir, and adding them when
entering. But it doesn't make the least sense in SGPropertyNode space, where
we already have everything to move in a tree.
- add R & W flags for TRACE_READ and TRACE_WRITE. Remember: lower case letters:

- remove some verbosity & further cleanup ... to make further work easier :-)
- PropertyObject: remove additional "values" member again
- don't create entry lists for <list>, <select>, and <combo> at dialog
creation and delete them on dialog close, but let a separate class
fgValueList handle this. The three widgets are now subclassed and the
derived widget lets fgValueList manage the lists
- make <select> consistent with <list>. This breaks backwards
compatibility, but not a single dialog in fgfs uses it and did so
since ... forever. (Shoot me!)
Rationale: now that dialogs are a bit more dynamic than they used to be
(thanks to embedded Nasal), we have to delete and recreate entry lists
during dialog use. Deleting only at dialog closing doesn't cut it anymore.
Especially list widgets that are updated several times per second would
use up a lot of memory otherwise. The route-manager doesn't update that
often, but it did already leak. One TODO less. :-)
signals, this is meant for attaching listeners. The ufo will use that to
hide/reveal the status line in screenshots. The following signal properties
are now available:
/sim/signals/exit ... set to 1 right before quitting
/sim/signals/reinit ... set to 1 on re-init (Shift-Esc)
/sim/signals/screenshot ... set to 1 before and to 0 after screenshot
/sim/signals/click ... set to 1 after mouse clicks at terrain, signalling
that the geo coords in /sim/input/click/ were updated

contents. The old contents are only freed at dialog close, which should
eventually get changed.
two almost identical functions for these methods. It only forces to repeat
the redundancy for every small change to either.

be removed once fgfs officially depends on a plib version that includes
the fix)

Fix that by setting the "DownCallback" for live input fields.

rethink that special meaning of negative coords altogether.
Erik Hofman:
This patch contains an update to net_ctrls.hxx that adds an extra 100 bytes
(or an equivalent of 25 (u)int32_t types) of reserved space. This could be
used to make the protocol forward and backward compatibel within a certain
scope. Be sure to read the instructions at the begining of the header file
when addinf new variables.
it's also possible to enable/disable menu/item entries with higher numbers.
This can be useful for adding entries from other config files (aircraft
specific or local). I'd say aircraft files can use indices starting with
[100] and local files starting with [1000]. Such high number will never
collide with an entry in menubar.xml, even if entries are added/removed
there.
Unfortunately, we don't have an easy way to access the puObjects
only by knowing the respective XML property node, because the
menu structure was built by plib from string lists. That's why
we walk the puMenuBar tree and store {property node}->{puObject*}
pairs in a map. With this infrastructure in place we can now
easily enable/disable entries, but we can also make other changes
to menu buttons as we see need. The structure of puMenuBar is
described in the pui documentation, so it's less of a hack than
it looks. :-)

that we never want to draw outside the screen area; for this to work
we need to write the original x/y coords back to overwrite the absolute,

bindings.
there was the situation where four directories contained jst two files,
of which three directories were aircraft related, and one directory contained
test code from Curt that might be better of in SimGear anyhow.
This is just a patch to move a bunch of files to new locations. In case of
local changes to any of them you can do the following:
move replay.[ch]xx from src/Replay to src/Aircraft
move control.[ch]xx from src/Control to src/Aircraft
move ssgEntityArray.[ch]xx from src/Objects to simgear/screen
In addition it has been decided only to use .[ch]xx files in all directories
unless it's contained within an FDM specific directory, in which case the
author is free to do whatever (s)he wants.
In this repspect the following files have been renamed in src/Multiplayer:
tiny_xdr.[ch]pp has become tiny_xdr.[ch]xx
multiplaymgr.[ch]pp has become multiplaymgr.[ch]xx
it isn't there, this is a bug. Thus centralize the error message so that it
doesn't have to be repeated everywhere. Of course, the calling code should
still consider that a returned property node may be 0.

or data blocks) from layouter and dialog creator. This is required for
dynamically generated/modified dialogs. Parts in the XML file can be
hidden and turned on by the C++ code. Other hidden parts can be used
as templates that are multiply used. Hidden datablocks can contain
strings that are used in dialog context, that are easier to translate
or modify in the XML file.
I have done a valgrind run in flightgear. Just start it up and close it at the
fist change I had about half an hour later.

This adds a TACAN instrument to the inventory. Range and bearing are calculated

Attached is a patch to the airport data storage that I would like committed
after review if acceptable. Currently the storage of airports mapped by ID
is by locally created objects - about 12 Meg or so created on the stack if
I am not mistaken. I've changed this to creating the airports on the heap,
and storing pointers to them - see FGAirportList.add(...) in
src/Airports/simple.cxx. I believe that this is probably better practice,
and it's certainly cured some strange problems I was seeing when accessing
the airport data with some gps unit code. Changes resulting from this have
cascaded through a few files which access the data - 11 files are modified
in all. Melchior and Durk - you might want to test this and shout if there
are problems since the metar and traffic code are probably the biggest
users of the airport data. I've also added a fuzzy search function that
returns the next matching airport code in ASCII sequence in order to
support gps units that have autocompletion of partially entered codes.
More generally, the simple airport class seems to have grown a lot with the
fairly recent addition of the parking, runway preference and schedule time
code. It is no longer just an encapsulation of the global airport data
file, and has grown to 552 bytes in size when unpopulated (about 1/2 a K!).
My personal opinion is that we should look to just store the basic data in
apt.dat for all global airports in a simple airport class, plus globally
needed data (metar available?), and then have the traffic, AI and ATC
subsystems create more advanced airports for themselves as needed in the
area of interest. Once a significant number of airports worldwide have
ground networks and parking defined, it will be impractical and unnecessary
to store them all in memory. That's just a thought for the future though.
Somehow the MIPSpro compiler doesn't like an STL map entry being called
using a variable when the reference is an object and not a pointer to an
object.
Preliminary support for a fontcache is added which prevents fonts from
being loaded more than once and takes care of freeing them up again.
The fontcache isn't used yet since there seems to be a problem somewhere.
I have traced that reset on carrier problem down to several problems. One of
them is the fact that on reset the carrier is updated while the aircraft is
not. That made the aircraft drop down an elevator sometimes. Depending on the
passed realtime while loading some parts of the scenery.
LayoutWidget::setDefaultFont() wants puFont* /and/ pointsize as extra

font similar to Helvetica/Swiss. The license doesn't allow to redistribute
modified fonts under the original name. While it's only a converted font,
and not manually modified, it can no longer be seen as original. Changes
so far are (a) conversion from vector to bitmap, (b) different empty space
width, (c) different & constant gap value, without other kerning information.
Further changes may be necessary in the future.

generated by freeglut's genfont utility. That application also generates
a copyright message that I did not copy into this file, because it is
wrong: the author of genfont claims copyright for data that *I* generated
using his program; this doesn't fly. Of course, the copyright will remain
in the (heavily edited) version of *his* code. I'll commit that, too.

- add <vrule>
