Hello ,I want to add a button which is not contained in xwiki by default,
on the toolbar of the wysiwyg editor ,I have read the java source of it
,and still have some problems .So I want to know is there any document
about this , for the plugin contains so complex and unfamiliar class to
me that I was puzzled(Of course ,most of the reason is that I am a newbie
in programmes. ) .Thank you .
