have no children (in which case they default to 1px thickness & stretch).
This allows to just write <hrule/> instead of <hrule><dummy/></hrule>.
One can still use <hrule><pref-height>3</pref-height></hrule>, of course.

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:
disabled (rw ... reading/writing), upper case letters: enabled (RWAUT)
- 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
only used by the <list> widget. It allows to "dialog-update" the list,
which rescans the <value> children and redraws the list widget with new
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.
- abstract out generation and destruction of plib string arrays
- abstract out generation of lists from <value> children

Nasal's cmdarg(). That way dialogs can generate dynamic content, such as
list entries.
list) and the arrows are clicked (patch sent to plib; workaround it to
be removed once fgfs officially depends on a plib version that includes
the fix)
- fix (very unlikely) crash in case the widget is redrawn between list
destruction and setting of the new list.

<property>, except if they are activated, in which case the user input

the user selected a different widget, then its contents were dropped.
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. :-)

because this creates an empty entry if it didn't exist. This made the

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
parameters, when puFont knows its pointsize anyway. Didn't want to change
that yet, though.) Now the HELVETICA_10 font makes actually sense. :-)
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.
[new_gui is] "using copies of puFont objects that are not yet initialized, I
think that dependant of link order (and so tor execution order) it can
work or not. Changing puFont font by puFont *font should work in all cases."
