Hi,

I want to be able to resize a font that is used within my styled JTextPane
so that it grows both horizontally and vertically when the form resizes.
I have the code to rescale the font (posted below), and that can be applied
to a label which works fine.

What I want to do is set this newly rescaled font as the font for the styled
JTextPane, but I cannot seem to make it work.
I have tried setting the font using textPane.setFont(), I have also tried
resetting the styles but there is only a fotnSize atrribute not a specific
method for setting the real font to be used for a style..

From the code below, assume that handleResize() is called from a component
listener - when the component resizes. This is definitely being called.
Assume also that addStyles() is using a JTextPane set as a class level var,
as is the _font.

The rescale appears to work for the label but not the text pane.
Any ideas,

Steve
