Hi, WebKit developers,

I'm trying to understand how plugins are supported in WebKit. At first, 
I'd like to implement a dummy plugin which can be used to handle any 
<object>, <embed> and <applet> tags and just prints the requested URL, 
mimeType, etc. passed to it.

Here is what I have done so far:
   - some methods in PluginInfoStore are implemented, including: 
createPluginInfoForPluginAtIndex, pluginCount, pluginNameForMIMEType, 
   - refreshPlugins method is implemented
   - createPlugin method in FrameLoaderClientJava is implemented
   - settings->setPluginsEnabled(true) is called
   - a new class PluginWidgetJava extends Widget is created and used in 
createPlugin method

When I load a page with any embedded objects like Flash clips, I get two 
method calls:


and the clip is replaced by server with an animated gif. What other 
stuff should I implement? Note, at the current moment I don't want to 
have an arbitrary NPAPI plugin working, just would like to understand 
the whole plugin-related machinery.
