From jtextpane to jeditorpane

Question

I'd like to create a complete text editor so, i made these two code, but the first it's based on jtextpane and the second on a jeditorpane. I want to link toghether the second with the firt code , to have a cpmplete text editor. The problem is that i don't know how to do this. The fisrt think i thought to do was transform the jtext in the fisrt code in a jeditor but jeditor don't recognize the function 'append' .. Could someone help me? Thanks

Answer 1

Sorry. My problem is that I want to insert HTML inside the body tag of an HTML page, and I don't know any simple method to get a reference to the <body> element from the JEditorPane widget, I get a reference to the actual HTML document but I can't get a reference of a tag from HTMLDocument either. Thanks.
