Here's the Airbus style:

Gijs and Hyde, could you please take a brief look and see if that breaks anything for you (if it does, please report back, if not, please commit those changes to fgdata): http://wiki.flightgear.org/Howto:Protot ... ge_changes

I've checked on 777 with this patch and not found any issue.
Gijs, Please check on 744 and push the change if it's OK.

Thanks,
Hyde

thanks for taking care of this, much appreciated !

For now, I will let this rest - but I am taking bug reports and feature requests - so anybody interested in creating a custom style, feel free to provide feedback to see if/how this can be made more useful, if in doubt add your ideas to the wiki article

Can anyone help me to solve the bug on the radial VOR which is not updated on change of the property "instrumentation/nav/radials/selected_deg" ?
I'm working on since 4 days without result :(

Like I said previously: we need to know, Is this issue specific to your changes or does it also appear with the default ND on the 744/772 ?
If in doubt, refer to the navdisplay code and its "controllers" for these things - these should trigger an update. If they don't, you have found a bug

Same problem on the 777.
The Airbus A330 doesn't display the radial VOR.

According to the code/property browser, the property name is selected-deg (dash/minus not underscore) - next, I would suggest to open the .mfd/.styles file and specifically look for any elements using that property and check the update predicate, for MapStructure layers proceed respectively - for debugging purposes, you can add print statements into the code to see if the code is getting called or not

Gijs, Please check on 744 and push the change if it's OK.


FYI: That is one of the reasons why I implemented the dialog so that it can show multiple different styles at once - so that people can more easily test different styles, without having to exit/restart fgfs or load other aircraft - for example, the OP mentioned he was going to develop a CitationX style - with the new dialog, the corresponding changes can be tested simultaneously - i.e. to make sure that they don't break the Boeing/Airbus styles, while the CitationX style is still under development.

Likewise, this should also make it much more straightforward to test refactoring related changes, such as cleaning up navdisplay.mfd (think the update() loop) - because the dialog will reload your changes from disk, without having to exit/restart fgfs, and it will display all styles at once.

This is the current state, in terms of code it gets away with being under 200 LOC (Nasal obviously):

http://wiki.flightgear.org/Howto:Protot ... play_Style

I am considering to directlly add a new "Citation" mode to the styles file that can be populated by others - obviously, that will require a new SVG file (compass rose, symbols etc) - but otherwise, developing new ND styles, and refactoring the existing ND code should be fairly straightforward now, because it is easy to directly test all sorts of features without having to load different aircraft.

And in fact, depending on how this unfolds (and spare time permitting obviously), the whole thing could be turned into some kind of "NavDisplay style editor" or even some integrated wizard to easily create/update styles without even having to use a text editor, which is one of the benefits of the declarative *.styles approach, because that can be easily converted to become XML or some other format that can be easily supported using a front-end like this.

It's a work in progress... but it takes a long time !!

I solved the problem with the radial vor !!!
For that, I followed the same method than the "range_dependant". I created a "course_dependant" for the VOR in the navdisplay.styles file and modified the navdisplay.mfd file to create "course_dependant_layers". It was also necessary to modify the VOR.symbol file.
The changes are identified by "##########" in the margin of each file.

http://www.mediafire.com/file/562gfpkfv2h2f22/navdisplay.styles
http://www.mediafire.com/file/ktmb3jd5ts60x7z/VOR.symbol

For the Citation and not to pollute the originals navdisplay files, I created NdDisplay ... files which are copies of the originals.

Are you familiar with using git, or if you aren't, would you be willing to review the corresponding tutorials on the wiki ?
If so, you could directly publish/share your changes via git (based on a fgdata clone ideally), so that they can be more easily reviewed/applied by Gijs and Hyde.

You can set up your own fgdata clone via sourceforge (see the wiki article for details), so that we can track your progress there - which will make it much easier for Gijs or Hyde to review your changes and get them committed.
