A JEditorPane is for displaying HTML.
You should be using a JTextArea if you are showing plain text or JTextPane if you are using text with attributes.
JTextArea has a get line height method.
JTextPane doesn't have a method but you can get the font of the JTextPane and then get the FontMetrics of the Font and then get the line height information from the metrics.

I use JEditorPane because c source code is not plain text.I insert html in it ,for keyword highlight.
The question is that FontMetrics does not work.
my code is :
jEditorpane.getFontMetrics(jEditorpane.getFont());
but the actual font is : <font size="..">...</font>.

Well you shouldn't be changing the font size of the text. Editors should just highlight keywords not change the size.

I would use a JTextPane then. Its easier to use attributes than to play with HTML. Simple example:

thats right. and this is why you should never say that c source code is not plain text. that conveys a wrong information to new people.regardsAniruddhaAniruddha-Herea at 2007-7-12 18:28:56 >
