使用NPAPI界面加载flash .swf

Question

I tried to write a program with load a SWF file directly, and I am going to use NPAPI to implement that program.

But, I don't know how to start it. I mean how to communication between cocoa and NPAPI? And how to build the architecture of program?

I searched Google in many times, there is no many useful information for this topic.

I hope anyone can help me.

Any suggestion will be appreciated.

Answer 1

Building an NPAPI host is non-trivial; if you really want to do it yourself from scratch your best bet would be to look at the source for Gecko, WebKit, and/or Chromium, and re-use whatever you can from there (assuming your app's source license makes that possible).

Other than that, Mozilla's NPAPI documentation is the best source, along with the list of accepted NPAPI extensions for more recent changes (since you mentioned the Mac, you'll need to read and understand at least the Cocoa, Core Graphics, Core Animation, and negotiation proposals). Just keep in mind that a lot of how NPAPI works is de-facto standard based on what other browsers do, so just the documentation won't be enough.

You mentioned in a comment that you don't want to use WebKit because of a "security issue"—if you know of a security issue in WebKit, why not fix it instead of building a really complicated system from scratch? It's very, very unlikely that if you make a from-scratch implementation of an NPAPI host you will end up making fewer security mistakes than exist in a mature implementation that's been tested, debugged, and improved over the course of a number of years.

Particularly given the amount of plugin background you seem to have so far, I would strongly recommend that you use FireBreath . It will at least get you through the plugin part. The rest is up to you, and it won't be simple.

One thing to know is that different browsers on Mac OS X use different drawing models and different event models. For event models, the general rule of thumb is that 32 bit browsers support Carbon and 64 bit support Cocoa, though some 32 bit browser support Cocoa. Depending on 32/64 bit and the browser (and version) you may need to draw with QuickDraw, Cocoa, CoreAnimation, or CoreGraphics.

There is more information about this on the FireBreath wiki (main website).
