The Nasal/Canvas data structures will be transparently created and compiled for each MFD. Each MFD consists of an arbitrary number of buttons, modes and pages. Each MFD can be instantiated multiple times, and each MFD is designed to be aircraft/instrument agnostic, i.e. also works just in a conventional Canvas dialog. Buttons can trigger and switch between modes, and modes may have pages (conventionally implemented through a single SVG file). Each page consists of an arbitrary number of page elements, which can in turn be animated/updated via listeners and timers. Should look at existing displays, especially the [[NavDisplay]] and the update() method in navdisplay.mfd, but the most complete test-case would probably be the [[Avidyne Entegra R9]] }} | The Nasal/Canvas data structures will be transparently created and compiled for each MFD.

[[File:Canvas-mfd-framework-prototyping.png|thumb|This is an adapted version of the [[Garmin GPSMap 196]] that is currently being developed by F-JJTH. Here, the whole instrument is entirely set up in XML space, including buttons/event handling, but also the embedded canvas region that serves as the 'screen'. The idea is to allow arbitrary MFDs to be specified in an aircraft-agnostic fashion, including displays like a PFD, [[NavDisplay]] or EFB. For details, please see [[Canvas Glass Cockpit Efforts]].]] | |||
