change tab size in JEditorPane

[Amer Qouneh]

Hi,

I am trying to change the size of TAB in an XML source document that
I open in a JEditorPane.
Now, it is 16 spaces I think, and I would like to make it 4.
JEditorPane does not have any public methods to set it to a new value
like JTextArea for example.
Does anyone know how to do this?

Thanks!
