JSpinner - disabled foreground color

Kurt Peters — Thu, Apr 23 2009 09:33:15 MDT

I have a JSpinner that I want to be able to optionally disable spinner input, but...

I still want to use the editor part as a display by slaving it to something else. That is working, but when I do a "setEnable(false)" the display turns gray.

I've tried significant options to make it NOT be gray, but can't get it to behave. I've defined
my own Jspinner class with

	@Override
	public void setForeground(Color inColor) {
		super.setForeground(inColor);
		 DefaultEditor editor = (DefaultEditor) getEditor();
	     editor.getTextField().setForeground(inColor);
	}

but that only changes the foreground in "NON DISABLED" mode. I need the foreground to change in DISABLED mode as well.

Any ideas?

As I said, I have my own JSpinner class now so modifying that isn't an issue.

Regards,
Kurt

JTextField tf = ((JSpinner.DefaultEditor)spinner.getEditor()).getTextField();
tf.setEnabled(false);
tf.setDisabledTextColor(UIManager.getColor("TextField.foreground"));

Thanks, that worked. How would a mere mortal figure that one out from the documentation?

My change foreground code is now:

	@Override
	public void setForeground(Color inColor) {
		super.setForeground(inColor);
		 DefaultEditor editor = (DefaultEditor) getEditor();
		 JTextField tf = editor.getTextField();
	     editor.getTextField().setForeground(inColor);
	     if (!isEnabled()) {
	    	 tf.setDisabledTextColor(UIManager.getColor("TextField.foreground"));
	     }
	}

I'm thinking it would get the color from the enabled one?

UIManager.getColor("TextField.foreground") gets whatever the 'default' is,
so should match the enabled one, but you can specify any color e.g.
tf.setDisabledTextColor(Color.YELLOW);

there is no real need to put it in the overridden setForeground().
on it's own in the constructor will do - once set, stays that value until changed,
regardless of whether the spinner is disabled/re-enabled/disabled again

forgot this bit

there are a huge number of methods in the JTextComponent api, so most of your document reading
in regard to text components (textfield, textArea etc) should be directed to "methods inherited from JTextComponent"
