== Background ==
No easy way to browse a list of available fonts in the base package
== Idea ==
Implement a simple font browser using Nasal and Canvas
== Approach ==
since FlightGear uses OpenSceneGraph, and since [http://www.openscenegraph.org/index.php/documentation/user-guides/61-osgplugins OSG supports TXF ],  we might use Nasal/Canvas to display a list of fonts and even preview them inside fgfs (?)
To see for yourself, modify the Canvas image example to point to a font file:
* [[Canvas_Snippets#Adding_Raster_Images]]
* [[Canvas_Image]]
If this works, this can be trivially extended to show a list of all fonts including a preview, by adapting this snippet: [[Canvas_Snippets#Canvas_ScrollArea]]
Alternatively, it would be possible to render the menubar completely using the Canvas system: [[Howto:Making_a_Canvas_Menubar]]
