Want to verify this is the cause of crashes inside the property code,
since if it's not we have a much bigger problem.
This means all listeners are recursive, with a parent-chain walk on each
setValue call, as has been the case since 'forever'.
COMPARE -> SG_CHECK_EQUAL
COMPARE_EP -> SG_CHECK_EQUAL_EP
COMPARE_EP2 -> SG_CHECK_EQUAL_EP2
VERIFY -> SG_VERIFY
Also remove duplicate private definitions of these macros in test
modules, using instead those defined in simgear/misc/test_macros.hxx.
Change most places we control (i.e not helper libs) to use SGPath
to represent a path, instead of using std::string. Extend SGPath
API to explicitly expose the path in either UTF-8 or the
system 8-bit encoding.
add a create-flag to the node() method of a PropertyObject,
defaulting to false to maintain existing behaviour.
This could be used to add a listener to a non-existing property
without having to write a dummy-value beforehand.
Usage:
myPropertyObject->node() returns the corresponding node or NULL if
does not exist or has not been accessed before.
myPropertyObject->node(true) returns the corresponding node, never NULL.
If the property does not exist, it will gets created.
No need for this anymore as PRESERVE now works as expected.
Otherwise old canvasses are restored and do not work anymore
as the placements of the new canvasses do not apply.
Get rid of the possibilty to keep delted children. This was not
used actively, required unnecessary memory for each property node
and lead to subtile bugs, as creating a node after a node with
the same path has been deleted resulted in getting the old node
back instead of a cleanly initialized one.
Store unhandled xml attributes in a subnode named _attr_ for each
node on parsing propertylist files. This allows retrieving them at
a later stage where there is no access to the source xml file any
more.
Search the tree for leaves / sub-trees with a particular attribute set.
This permits both sparse selection as well as selection by sub-tree.
(This is needed for PRESERVE attribute, and once new reset is switched
on, will enable 'normal' copyProperties to revert to ignoring
attributes completely)
- without this change, elements aren't un-ref-ed and hence destroyed
until the actual dtor runs, which is too late (other systems may be
destroyed already)
Bug 1190, fix route-manager -> GPS activation on Windows
(and probably a couple of unrelated issues).
SGPropertyChangeCallback was missing a suitable copy-constructor,
leading to incorrect behaviour on compilers where the operation
is not elided. Such as MSVC.
Nodes inside the osg scenegraph now hold a strong reference to
the according canvas element. Canvas elements in turn now only
hold a weak reference to the according node. This simplifies
for example the canvas::Group as it does not need to keep a
list of children on its own anymore. This is now stored inside
the scenegraph (as it was already before).
The restructuring will also allow to use a canvas::Group for
the canvas gui inside FlightGear and share for example the
handling of stacking based on z-index.
