I am using html to create a multiline JButton, which works fine, but
when i disable the jbutton, the text is still the same color (it is not
faded), however, the Jbutton does become disabled.

anyone else run into this problem?

yes, did you read also about workaround there?

I suggest however to use a slightly another solution:

public class HtmlButton2 extends JButton {
private String html = "<html>";
private String disabledColor = "<font color=\"gray\">";

String enabledText;
String disabledText;
boolean isHtml;

public HtmlButton2() {
super();
}

public HtmlButton2(String text) {
super(text);
}

public void setText(String text) {
if (text.startsWith(html)) {
isHtml = true;
enabledText = text;
text = text.substring(html.length());
disabledText = html + disabledColor + text;

if (isEnabled()) {
setTextImpl(enabledText);
}
else {
setTextImpl(disabledText);
}
}
else {
isHtml = false;
enabledText = text;
disabledText = text;
setTextImpl(enabledText);
}
}

protected void setTextImpl(String text) {
super.setText(text);
}

public void setEnabled(boolean b) {
if (isHtml) {
if (b) {
setTextImpl(enabledText);
}
else {
setTextImpl(disabledText);
}
}
super.setEnabled(b);
}
}

Hi Andrey,

I tried this, and I got a problem at first, and found that you needed
to set the html and disabled fields as static, and then everything
works out. Thanks!
