Hi All,
I am using Windows XP and jdk1.6.0_16
On a JPanel, I want to make a simple 4 rows by 4
columns: a grid/ "scratch pad" that I can list two digit
numbers i.e. 10,12,...45.. one number each of the 16 cells.
I have tried a TextArea to do that. But using tabs is
a problem, to make it appear to be rows, columns.
Yet in a further search for a suitable demo,
this demo was written to demonstrate a TextPane. But while
testing/reading there was coding error of
"int tabWidth = charWidth charactersPerTab;"

This line of the example is missing the * to multiply the character
width by the number of characters per tab.

In reading for further discovery the
This read:
"Note that the implementations of these methods are
inefficient, so they are usually overridden with more
efficient toolkit-specific implementations."

I am looking for further help with this problem
Your help is appreciated.

I'm not sure I would tackle the problem this way. I would probably just
use a grid of JLabels and post my numbers in those. Or I would draw
them directly onto a JPanel if I needed more complicated formatting.
