FGQCanvas

A Qt-based remote canvas application for FlightGear. This app can connect to a FlightGear instance which has the built-in HTTPD server enabled and display any canvas in real-time.

Usage

Start FlightGear with the '--httpd' option, passing a port number. This can be done in the 'additional options' box if using the launcher.

• --httpd=8080

Start FGQCanvas and enter the WebSocket url, with a suitable host-name and port. Provide the path to the Canvas you want to display (this part will become smarter in the future!)

Examples URLs:

• ws://localhost:8080/PropertyTreeMirror
• ws://mycomputer.local:8001/PropertyTreeMirror

Example Canvas path:

• /canvas/by-index/texture[0]/

Limitations

• Clipping is still being worked on
• Fonts are not loaded from the host instance yet
• Image loading is still being worked on, no support for remote image loading yet.
• Performance is mediocre due to proof-of-concept implementation
• No input event support yet

Future plans

• Finish image, clip and font loading
• Switch to OpenGL rendering
• Support event-input to the Canvas
• Rewrite to use Skia
