I just started learning Java, and as a result made my first

Never mind the rest of the page; please look at the applet at the
bottom of the page. There is also a link to the source code. The
applet uses only what I believe to be "basic" Java, awt (no
Swing), basically because, well, I haven't studied that far yet.

I tried it only with the few computers and browsers that I have
access to, and it seemed to be alright. But some then on-line
viewers (I think mostly Mac users) complained that the font is too
big, so some of the labels near the buttons are not shown
completely, being crowded out by neighbouring buttons.

I do not use a layout manager; all buttons etc. get their
positioning from "setBounds", which specifies their location in
pixels.

The applet does not specify anything related to fonts, so I
suppose it uses some default. Is it possible to set this default
(in pixel size) such that it works on all systems?

Thanks in advance, Jan

Your applet is very cool. I found no problems with font size or layout
issues. As you have discovered however they do show up on some
platforms. Layout managers are fairly easy to use but you would have to
do some redesign of your Applet. Commonly, graphics are drawn onto
Panels or Canvases. These components can then be added to a top level
container such as an Applet or Frame.

I did find one interesting thing in your code that is often seen in
folks transitioning from C/C++.

C[0] = (M[0].x < 0) ? true : false;

< returns a boolean so your code would be the equivalent of:

if (M[0].x < 0 == true)
C[0] = true;
else
C[0] = false;

C[0] = M[0].x < 0;

will suffice and to a Java program eminently more readable.
