I want to have a checkbox with multi-line text and I want to disable it sometimes.
- Simple JCheckBox works fine and gets disabled, but it's not multiline.
- Putting <html>line1<br>line2</html> provides correct size and layout, but when I disable the control, only the checkbox itself is grayed, the text remains black.
- I know I can change the HTML text color to gray, but this will not work for the "Classic Windows" look-and-feel where disabled text should rendered as "sunken". Or, actually, it will work, but the appearance will differ from other disabled controls nearby, which is not good.
- I can create a simple JCheckBox containing the first line of text and a JLabel with the second line and disable them simultaneously, but clicking the second line (the JLabel) doesn't activate the checkbox, and clicking the checkbox displays the keyboard focus only around the first line which confuses the user.
Is it possible to have a checkbox and its label as separate controls and have some kind of link between them, as in HTML? Probably I would be able to cook something from this.
Is it possible to subclass JButton and override something there, for example, to change the way the focus rectangle is drawn? The rectangle is drawn by com.sun.java.swing.plaf.windows.WindowsButtonUI but I'm kinda afraid of subclassing that class because it's too deep in the standard library and my application may break with a new JRE.
