How to get line number of current cursor?

Posted: 4/19/2006 12:12:00 PM

java-programmer, How to get line number of current cursor? I try to get the line number of current that cursor is on from the
JEditorPane.
I found method getSelectionStart() and getSelectedText(), but it not
has the getSelectedLine() or ...

So, anyone know how to get the current line number that cursor is on.
Thanks.

This depends on your document. E.g. if you use a
javax.swing.text.PlainDocument, then it should be easy:

JEditorPane editor = ...
PlainDocument doc = (PlainDocument) editor.getDocument();
int offset = editor.getCaretPosition();
int lineNbr = doc.getDefaultRootElement().getElementIndex(offset);

Other document types behave totally different. E.g. HTMLDocument builds
a hierarchical Element structure where each Element represents a
structural block of HTML, and not just a line of text.
