where chosen to match the SGPropertyNode::WRITE/READ symbol names and
should make it more consistent, but this isn't really something that
should be exposed to the Nasal developer.)
* depreciate __xmlFindNextElement and use __xmlGetNode instead
* xmlGetNextElement now returns char* instead of void* for furute use
* add preliminary support for wildcards in the search path ('*' and '?')
them to the final place depending on OS and Desktop Environment (just
like man pages and binaries). Otherwise the installer would need access to
$FG_ROOT only for the icons, which is an undesirable dependency.
[1] there's a lock on the $FG_ROOT/icons/ dir, so I'll remove
them later from the old place.
we know the stack trace), it's better to use a separate function for
it, as this can be used conditionally, as in:
setlistener("/the/property", func(n) {
if (n.getValue() < 0) # who's writing negative numbers to /the/property?!
abort(); # let's check the backtrace ...
});
and its function called. This is useful for debugging purposes, to get
a core dump which unveils which C++ code was writing to the property.
This isn't any more of a security problem as other Nasal code that
makes fgfs crash, such as: var x = func call(x); x(); The difference
is that the listener doesn't use up all memory before and is much quicker.
- don't allow to do that from any XML file. This is to prevent malign
code from writing a new fg-home in ~/.fgfs/autosave.xml or other files
in ~/.fgfs/.
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.
- don't keep oodles of class member variables public (eek!)
- use ::hasValue() instead of ::getType() != SGPropertyNode::NONE
- consistency fixes and cosmetics
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.
