Setting font of JSlider

[Fred]

How do I set the font of a JSlider after it has been created, such
that its size is correct if it is the child of a JPanel used to
display a border ? (I use the JPanel for the border instead of
putting the border on the JPanel because using Nimbus L&F the
JSlider's border gets drawn inside the JSlider, clipping its contents)

I create a JSlider and a Hashtable for the tickmark labels, then
create the ticmark labels.

Then later I try to set the font.
If I just set the font on the jSlider, nothing happens. I have to set
the font on each of the labels for the font to change. But then the
jSlider's width is incorrect, clipping the labels.

Even if I do not use Nimbus, the problem occurs.

slider.setMajorTickSpacing( 20 );
f = new Font( "Monospaced", Font.BOLD, 20 );

String smin = "10.000";
JLabel lab;
lab = new JLabel( smin );
// lab.setFont( f ); // If done here, the size is correct
labelTable.put( 0, lab );
slider.setLabelTable( labelTable );

Yup, it clips. After about a font size of 22, I get pretty noticeable
clipping. Also, the labels tend to display on top of each other.

Dems the breaks. Code has bugs. Submit a bug report to Oracle, and it
might be fixed in Java 8.

22 is a pretty big font size. Do you really need labels that big?

[Fred]

No, I don't. I was just using it in this example to make it obvious
that clipping happened.

Just to preface: I didn't copy and run your example, I made my own from
scratch, just to make certain that there weren't any hard to spot
assumptions in the code.

My code did not exhibit any clipping at all, that I could see, until at
LEAST 22 point. It was slightly visible on the bottom (first) 0 on the
scale. At 30-50 point, it was pretty unsightly. The font mattered too,
with some "bold" fonts not clipping at all until at least 50 point or so.

If you want my code as a base, I'll post it, but it's a little
complicated. I generated most of it with a GUI tool and the tool makes
a verbose amount of code. I think it's still readable though.

I am hazy on the details, but most of the trouble I remember came from
composite components. You have to get at the inner components of the
composite, and fiddle them individually.

The notes I wrote when the details were fresh should explain it. I
know for sure that applies to spinners, but I am not so sure it also
applies to sliders.

When I wrote my DateSpinner class, I propagated setxxx on the whole to
the relevant components. Sun should have done the same.

I can't come to bed just yet. Somebody is wrong on the Internet.

Another thing that will drive you batty is the rendering of such
elements can change quite drastically with the L&F. In other words,
there are L&F-specific bugs. You have check out how it looks in all
the L&Fs you permit.
