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.
The general idea is to help clean up some aspects of the FDM init and be
able to provide startup conditions in a less ambiguous manner.
Previously, things like positions, orientations, and velocites were set on
"the bus". These had to be read by the FDMs which then were supposed to
initialized themselves to those values and turn write around and start
modifying those values. It was messy and cumbersome.
Now, all the initial fdm conditions are written to a sub-[property-]tree
under /sim/presets/
The values in /sim/presets/ always stay set to what the user has specified.
The user can change these at his/her liesure, and then request a "reset"
which will reset to the new conditions. I don't even want to say how this
worked before. :-)
Now, an script, or gui interface can stage a set of initial conditions while
the sim is running (without disrupting it), and then call "reset" to commit
the change.
People who should worry about all this are FDM writters, and a small few
others who care about over all program structure and flow.
This adds supports for a language specific font, defined in locale.xml
I've also moved the fgInitLocale() routine from main.cxx to fg_init.cxx
to prevent an ungly extern definition in options.cxx.
When the scroll bar slider is dragged, the list scrolls only far
enough to see all items; only the arrow buttons can scroll it so far
that the last item goes to the top of the view.
Fix scroll bar proportional size: was wrong when the list was only
a little longer than the visible area.
Minor fixes such as "delete files[i];" -> "delete[] files[i];"
(where the item being deleted is an array of characters) and removal of
global variables.
Smooth scrolling when dragging the slider: one item at a time,
rather than one tenth of the list at a time.
Fix a bug that would have occurred if instantiated with arrows=2.
Sort properties primarily by name and then by numerical index
order, rather than a simple ASCII string order. E.g. "js[1]", "js[2]",
"js[10]" rather than "js[1]", "js[10]", "js[2]".
Avoid crashing if the selected property path does not exist;
display an empty list instead. This cannot happen when the property
picker is working properly, but did happen due to missing indices prior
to this patch, and could happen if the user is allowed to type a
pathname, as in the http and telnet interfaces.
Fix truncation of strings to PUSTRING_MAX: was wrong when string
length was exactly 80.
Fix: move the scroll bar to the top each time a new list is
displayed. It was left at its previous position, while the top of the
new list was displayed, not corresponding to the slider.
Use getDisplayName instead of duplicated code: gives a better
decision on whether to display the index, and avoids invalid property
paths being generated which would previously crash find_props().
Replace unnecessary node lookups by name with direct access: tidier
and more efficient. E.g. "getValueTypeString
(node->getNode(name.c_str()))" -> "getValueTypeString (child)".
Here is a FGIO class derived from FGSubsystem that replaces the fgIOInit()
and fgIOProcess() functions. The FGIO::update(double delta) doesn't use the
delta argument yet. I suspect it could be used as a replacement for the
calculated interval value but I'm not familiar enough with that piece of code
just yet.
I've also added two "command properties" to fg_commands.cxx that select the
next or previous view. Writing any value to these properties triggers the
corresponding action. As an example I modified my keyboard.xml:
<key n="118">
<name>v</name>
<desc>Next view</desc>
<binding>
<command>property-assign</command>
<property>/command/view/next</property>
<value type="bool">true</value>
</binding>
</key>
<key n="86">
<name>V</name>
<desc>Prev view</desc>
<binding>
<command>property-assign</command>
<property>/command/view/prev</property>
<value type="bool">true</value>
</binding>
</key>
And of course these actions can also be triggered from external scripts via
the props server.
- Removed some old cruft.
- Removed some support for older versions of automake which technically was
correct, but caused the newer automakes to squawk warnings during an
initial sanity check (which isn't done very intelligently.)
NOTE: this fix is technically not correct for older version of automake.
These older version use the variable "INCLUDES" internally and could have
them already set to an important value. That is why we were appending
our values to them. However, newer versions of automake don't set this
value themselves so it is an error to append to a non-existant variable.
We seem to "get away" with overwriting the value on older versions of
automake, but if you have problems, consider upgrading to at least
automake-1.5.

Turns out it was a problem with a long string, not the font. Plib is limited
to 80 characters in things like this listbox. BTW I checked and all the fonts
are missing those characters. So, no point in changing.
Description:
Fixed segfault caused by long string.
