This is a plugin sample which demonstrates how with minimal modifications
|
|
in the 4.x legacy plugin code to achieve scripting functionality despite
|
|
of Mozilla not supporting LiveConnect in the way it was supported in
|
|
Netscape Communicator.
|
|
|
|
To build the sample:
|
|
|
|
1. create .xpt and nsI4xScrPlugin.h out of nsI4xScrPlugin.idl file
|
|
using Netscape idl compiler xpidl.exe. The command options are:
|
|
xpidl -m header nsI4xScrPlugin.idl
|
|
xpidl -m typelib nsI4xScrPlugin.idl
|
|
nsISupports.idl and nsrootidl.idl are needed for this.
|
|
|
|
2. create a project and build np4xscr.dll -- the plugin itself
|
|
|
|
3. place .xpt file in the components directory and the dll in the
|
|
plugins directory
|
|
|
|
4. load test.html and see it in work
|
|
|
|
The current sample code was written for Windows but can be easily
|
|
modified for other platforms.
|
|
|
|
Important notice: although developers who work on xpcom plugins
|
|
are strongly encouraged to use Netscape macros for common interface
|
|
method declarations and implementations, in the present sample we
|
|
decided to use their manual implementation. This is because the technique
|
|
shown in the sample may be useful for plugins which are supposed to
|
|
work under both Mozilla based browsers and Netscape Communicator
|
|
(4.x browsers). Using the macros requires linking against some
|
|
libraries which are not present in 4.x browsers (xpcom.lib, nspr.lib).
|
|
|
|
Files which under other circumstances would benefit from using
|
|
the macros are nsScriptablePeer.h and nsScriptablePeer.cpp. The versions
|
|
which use macros are also included (nsScriptablePeer1.h and
|
|
nsScriptablePeer1.cpp) for reference purposes.
|
|
|
|
Some header files from mozilla/dist/include and some .idl files from
|
|
mozilla/dist/idl are still needed to successfully build the sample.
