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
"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.
