[Mozile] Just the commands, please

[James A. Overton]

Hi Gary,

You're right that the docs don't give a good explanation for how to  
do what you want to do. So I put together a new demo:

http://mozile.mozdev.org/0.8/demos/custom.html

The demo uses the Mozile rich editing code and the default Mozile  
Editing Scheme, but not the GUI and toolbar. Some example commands  
are created using JavaScript. You can also create custom commands by  
modifying the lib/xhtml.rng file, and the docs explain how to do that.

You call can call any command using mozile.execCommand 
('commandName'), and that will execute the command and add it to the  
undo stack. In the demo I call mozile.execCommand() with "onclick"  
event handlers.

The default MES defines a whole range of commands. If you don't want  
these commands you can remove this line

	mozile.useSchema("lib/xhtml.rng");

and then then only the commands you define will be available.

As for defining new commands, there are lots of examples in lib/ 
xhtml.rng, a couple more in the new demo, and there's this  
documentation which summarizes the various command classes:

file:///Users/james/Development/CVS/mozile/www/0.8/doc/html/ 
mozile.html#Commands

You can usually do what you want by using Wrap, Insert, Replace, or  
Style. More advanced commands start with the Command class and then  
define new test(), prepare(), execute(), and unexecute() methods.

Let me know if this new demo is what you're looking for, and what  
else you need to know.

James
