How do I get a JEditorPane to highlight the full width of a line (not just the text)?

---------------------------------
|Here is some text                |
|some more text                   |
 ---------------------------------

---------------------------------
[Here is some text]               |
|some more text                   |
 ---------------------------------

---------------------------------
[Here is some text                ]
|some more text                   |
 ---------------------------------

textPane.setSelectionColor(new Color(1.0f, 1.0f, 1.0f, 0.0f));
