Purpose

To create a DirectFB native backend for Mozilla. See below for more detailed goals and milestones.

Introduction / Motivation

Many of DirectFBs users seem to developing embedded multimedia applications. Its low level nature, running under linux, the low memory footprint and the many powerful graphics functions make DirectFB a natural choice for such applications.

A common practice for such applications, especially strongly upheld in the new area of 'Enhanced Television', is to create the interfaces for the application using Browser technology. Such interfaces typically make heavy use of JavaScript and Dynamic HTML to enable a familiar user experience for the application.

The use of a browser can also be imagined in many other applications, providing a good motivation to port a browser to DFB. Mozilla, as the Open Source alternative with the most fully developed JavaScript and DHTML support, is the best choice of browser.

Approach

Initial examination and discussion of the code seems to point in the direction of the BeOS or MacOS Mozilla backend being the best starting point for a DFB port.

Goals / Milestones

Possible goals:

• Gecko display under DFB
• Mouse control under DFB
• Firefox for DFB
• Minimo for DFB
• Clipboard Support (?)
• Drag and Drop Support (?)
• Moving window positions / adjusting sizes from JavaScript
• Controlling window transparency from JavaScript
• Controlling video provider from JavaScript
