Allow for advanced animations using easing functions and adapters
for interpolating specific property types (eg. CSS colors).
Old behavior should not have changed.
Ensure canvas displayed inside GUI windows are updated in the same
frame as the according window is made visible. This prevents
showing previous contents for the first frame.
This gives nice cursors when hovering and dragging slider and knob-animations, and the cursor is set correctly on mouse-up after the drag too. Makes directional knobs/sliders much easier to understand.
Ensure all FGPositioned related functions return SGSharedPtr
instead of raw pointers to allow automatic conversion to
nasal ghosts without custom helper functions.
Some cockpits rely on mouse position props being updated even when using a dragged pick-callback. Thanks to Clement for noticing. Re-structured so however we process the mouse (PUI, pick-callback, normal motion), we always update the props.
This adds the framework for platform cursor implementations; Windows and X11 to be done.
It also extend the mouse-input code to generate hover events suitable for driving tooltips.
Note there should be no visible functionality change from this commit, since everything
is inactive until fgdata changes are made.
For now it is available in the positioned Nasal
module. FGAirport is fully ported, but especially
procedures/navaids and free functions are still
missing.
Check for the 3rdparty dir in the parent of build dir, not the parent of the source dir. For the recommended build layout, this is the same location, but for super-builds using fgmeta it's not (and the source tree should not be touched).
If this causes anyone issues, please let me know, since it's possible more flexibility is needed to set the path explicitly.
In preparation for adding POI data, extend the FGPositioned type enum, and the cache code to handle arbitrary POI types. (Adding more in the future is straightforward now)
Also support removing user waypoints, which was requested by the Garmin G196 developers.
This was a bogus concept, either runways have a reciprocal or not (if singled-ended), really this was simply exposing an artefact of the apt.dat encoding. Change to an API which gives what is actually wanted - the ability to extract an airport's runways without any reciprocals included.
