public static class HTMLEditorKit.InsertHTMLTextAction

extends HTMLEditorKit.HTMLTextAction

InsertHTMLTextAction can be used to insert an arbitrary string of HTML into an existing HTML document. At least two HTML.Tags need to be supplied. The first Tag, parentTag, identifies the parent in the document to add the elements to. The second tag, addTag, identifies the first tag that should be added to the document as seen in the HTML string. One important thing to remember, is that the parser is going to generate all the appropriate tags, even if they aren't in the HTML string passed in.

For example, lets say you wanted to create an action to insert a table into the body. The parentTag would be HTML.Tag.BODY, addTag would be HTML.Tag.TABLE, and the string could be something like <table><tr><td></td></tr></table>.

There is also an option to supply an alternate parentTag and addTag. These will be checked for if there is no parentTag at offset.

protected void insertHTML(JEditorPane editor,

A cover for HTMLEditorKit.insertHTML. If an exception it thrown it is wrapped in a RuntimeException and thrown.

protected void insertAtBoundary(JEditorPane editor,
                                HTMLDocument doc,
                                int offset,

This is invoked when inserting at a boundary. It determines the number of pops, and then the number of pushes that need to be performed, and then invokes insertHTML.

Since:

1.3

insertAtBoundry

protected void insertAtBoundry(JEditorPane editor,
                               HTMLDocument doc,
                               int offset,

Deprecated. As of Java 2 platform v1.3, use insertAtBoundary

This is invoked when inserting at a boundary. It determines the number of pops, and then the number of pushes that need to be performed, and then invokes insertHTML.

                      HTML.Tag tag,
                      HTML.Tag addTag)

If there is an Element with name tag at offset, this will invoke either insertAtBoundary or insertHTML. This returns true if there is a match, and one of the inserts is invoked.

adjustSelection

void adjustSelection(JEditorPane pane,
                     HTMLDocument doc,
                     int startOffset,
