Description

create a Jlabel using the html tags.
do not set the foreground/background colors
via the html
The text will show up black. If you have a Look and Feel
that has a
black/dark background, the text cannot be read.
I cannont set explicitly set the
color because the LnF could
be switched back to a light background - which
would cause
light colored text to be difficult to read.
Code:
package solipsys.lf.plutonium;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Test {
static JFrame foo;
public static void main( String[] arg )
{
try {
UIManager.setLookAndFeel( "solipsys.lf.plutonium.PlutoniumLookAndFeel" );
} catch ( Exception e ) { }
foo = new JFrame( "HTML TAG TEST" );
foo.setSize( 500, 200 );
foo.getContentPane().setLayout( new GridLayout( 3, 1 ) );
foo.getContentPane().add( new JLabel( "You Can Read this. There is a label beneath this too." ));
foo.getContentPane().add( new JLabel( "<html><body> Can You Read This? </a></body></html>" ));
JButton sw = new JButton( "Switch to Motif" );
sw.addActionListener( new ActionListener() {
public void actionPerformed( ActionEvent evt ) {
try {
UIManager.setLookAndFeel( "com.sun.java.swing.plaf.motif.MotifLookAndFeel" );
SwingUtilities.updateComponentTreeUI( foo );
} catch ( Exception e ) { e.printStackTrace(); }
}
});
foo.getContentPane().add(sw );
foo.setVisible( true );
}

As the submitter points out, the html support does not pick up the background/foreground/font from the component it is in. This should be changed (although at this point changing it to pick up the colors might cause developers confusion).

Ok, BasicDocument (a subclass of HTMLDocument) now registers a special subclass of Color for the body foreground color. When getForeground is invoked if the return value is this special color, implying the developer hasn't specifically set a color in the html, the foreground from the component is returned.

Suns HTML text implementation doesn't fit in very well
with the way things are done regularly. Supposing
you had specified a color and the UI's L&F was supported,
which color is used in that case. The complete lack
of documentation describing the use of html text
and it's effects is pretty annoying too.
Why when
I put html text on a jbutton and then disable it,
is the text not disabled?
Why can't I have more than one line of text in a label
or button without using html text and without subclassing
the component and using 1 label for each line of text?
I guess Sun never thought "gee maybe people will want to put
more than one line of text on a button and have it
work predictably".

In the latest Swing (it says 1.2.2) I got with JBuilder
3.5, using HTML text in a JLabel still resulted in the text
being printed in black. The setForeground() Color I used
for the JLabel and the setFont() Font that I set for the
JLabel did NOT appear when the JLabel was displayed.
