Make fdm listener single-fire, don't listen to /sim/signals/reinit. This
allows the Canvas to stay with the same placement through reinit, after
both the 777 and 747 were having problems. I don't see any reason for
having to recreate it all, and the cleanup function is still there (e.g.
for independent windows, to have their .del() call the ND's .del()).
renamed handle_reinit() -> del()
This also makes sure the /canvas/by-index/canvas[3/4]/ nodes are removed
and then recrated, as well as making sure the MapStructure del() path is
followed and working. Unfortunately the NDs are still blank after reinit.
In time for 3.0. The API is still not fully complete, and not fully
cleaned up, but this is good enough for this release cycle (and it
should offer benefit longer term, if not now -- hopefully performance as
well).
Many thanks to Hooray as well, who has helped prepare things while I
could not, and often suggested ideas.
- move SVG to Canvas directory
- add basic wxradar
- differentiate between track and heading
- improve altitude arc
- add range arcs
- display correct ETA for next waypoint
- get rid of global variables and use instance variables
- identified all important drawing routines and move them into *.draw files
- changed to dynamic loading of *.draw *.model and *.layer files
- implemented poor-man's controller hash to move use-case specific conditionals out of the draw files, and back into the instantiation, i.e. Gijs' EFIS class
- started identifying stuff that is not specific to drawing, but to what is to be drawn, i.e. Model stuff - such as positioned queries, moved those out into *.model files
- some more work on supporting more than a single ND MFD instance per aircraft
- renamed a handful of SVG identifiers to avoid naming conflicts and to simplify usage of SVG IDs as member fields
- moved all of the setlistener setup out of the fdm-initialized stub right into the ctor of the Efis class (actually that's controller stuff...)
- initial MapStructure framework
- aircraft-agnostic NavDisplay class
- preparations for deprecating map.nas
- additions to canvas.map
- preparations for making NDStyles configurable via XML
- first stab at refactoring the map.nas module, and trying to let the API evolve according to our requirements
- split up the module into separate files (some of them will disappear soon)
- split up the "drawing" loops into separate functions so that they can be individually called
- move actual "drawing" to map_layers.nas
- introduce some OOP helpers to prepare a pure Layer-based design
- prepare helpers: LayeredMap, GenericMap, AirportMap (TODO: use a real "Layer" class)
- move airport features (taxiways, runways, parking, tower) to separate layers (i.e. canvas groups)
- avoid using a single update callback and use different layer-specific callbacks to update individual layers more efficiently
- add some boilerplate hashes to prepare the MVC design
- allow lazy updating of layers, where canvas groups are only populated on demand, to save some time during instantiation, i.e. loading an airport without "parking" selected, will only populate the layer once the checkbox is checked
- extend the original code such that it supports showing multiple airports at once
- add some proof of concept "navaid" layer using SVG files for navaid symbols (added only NDB symbol from wikimedia commons)
regressions:
- runway highlighting needs to be re-implemented
- parking highlighting will be done differently
- enforcing a specific drawing order for layers is currently not explicitly supported, so that taxiways may be rendered on top of runways
Also:
- integrated with the latest changes in git/master (HEAD) -i.e. metar support
- further generalized map.nas
- partially moved instantiation from Nasal space to XML space (WIP)
- create "toggle layer" checkboxes procedurally in Nasal space
- prepared the code to be better reusable in other dialogs (e.g. route manager, map dialog etc)
- completely removed the "highlighting" (runway/parking) feature for now, because we talked about re-implementing it anyhow
