Delphi开发npapi插件demo

Netscape Plugin Delphi Framework ================================ 26th December 1996 --- Mike Scott 100140.2420@compuserve.com The zip file contains a Netscape Navigator plugin framework and demo that shows how to make a Delphi form into a plugin. The files supplied are as follows: NPPlugin.pas The main plugin unit containing translations of the Netscape plugin interface and the Delphi plugin object-oriented framework which allows plugins to be created simply by subclassing from a TPlugin class then registering that class with the framework. NPSubCls.pas Contains a TPlugin subclass that subclasses the plugin window's window procedure. This allows you to intercept and handle Windows messages that are sent to the plugin window which Navigator creates for you to display your plugin in. NPForm.pas Contains a TForm descendant, TPluginForm, which you can use to turn Delphi forms into plugins. Simply descend your forms from TPluginForm and call the RegisterPluginForm procedure to tell the plugin framework which form class to instantiate for a given MIME type or set of MIME types. NPDemo.dpr A demo plugin DLL that you can compile with Delphi. Test.pas A simple test form that is turned into a plugin in Test.dfm the NPDemo sample. Plugin.rc A sample resource script showing how you set up the version info which Netscape Navigator uses to determine when to load your plugin. You need to set the MIME types that your plugin will respond to (or file extensions). Use BRCC to compile your resource script to a RES file. Plugin.res Compiled version of Plugin.rc resource file. NPDemo.html Sample HTML page showing an example of an EMBED tag that will load the NPDemo sample plugin. IMPORTANT ========= Netscape forgot to put this in the plugin SDK docs, but the name of a plugin DLL must begin with the letters 'NP', e.g. NPDEMO.DLL. If it doesn't then Navigator will refuse to have anything to do with it. Copyright (c) 1996 Mike Scott All Rights Reserved.
