JDateChooser setEnabled Color
Biagio
I'm using the powerfull JDateChooser JCalendar library 1.3.3.
Unfortunately, when the component is setEnabled (false) the color of
date is a gray almost unreadable.
I tried to change color, but when the component is disabled is not
possibile, it is always gray.
I would like to get a look like JTextField.setEditable (false).
Does anyone have any suggestions?
Thanks
Biagio

I assume you mean com.toedter.calendar.JDateChooser, found here:

The color has nothing to do with JDateChooser; it is specified by the
user interface default, which varies for each look and feel.

Because JDateChooser has a com.toedter.calendar.JTextFieldDateEditor, a
subclass of javax.swing.JFormattedTextField, you can set the disabled
color of any particular instance:
JDateChooser jdc = new JDateChooser();
jdc.setEnabled(false);
((JTextFieldDateEditor)jdc.getDateEditor())
.setDisabledTextColor(Color.darkGray);
Alternatively, you can change the UI manager's default, but I'd be wary
of veering too far from the familiar interface; it may be worthwhile to
choose a color derived from the expected value.
String name = "FormattedTextField.inactiveForeground";
ColorUIResource color = (ColorUIResource) UIManager.get(name);
UIManager.put(name, color.darker());
As an aside, I was recently critical of the demo's layout:
<http://groups.google.com/group/comp.lang.java.programmer/msg/39c807ad8e131973>
Line 132 in com.toedter.calendar.demo.JCalendarDemo is the problem:
splitPane.setDividerLocation(190);
Simply remove it to allow pack() to do the right thing.

Ah - didn't realise it was only the demo program you were unhappy about...
Anyway, the aforementioned additions were:
- nullText property - if the JDC's date is null then display any null
text, for example "Open Ended"
- selectOnFocus property - optionally select the text when the editor
gets the focus
- dateVerifier property - an interface that JDC calls back on to allow
client code to indicate whether a date is selectable; calendar buttons
are disabled for invalid dates and the editors skip to the next valid
date in the "direction of travel"
- use action map to (ctrl-c) popup the calendar; (ctrl-n) set to null
- provide access to the DateFormat inside so you can (eg) set its timezone
I'm in the process of pulling together other people's mods and will
github all this soon...

Honestly, I didn't know either. :-) It was just the first thing I ran
across, and I feared it was an ill omen. Of course, the more I use it,
the more I like it.

The dateVerifier looked especially appealing, although I'd since
reverted to the stock 1.3.3. It's clear you've worked with it
extensively; I'd welcome any comment you have on my response to the OP.

Excellent.

Looks like its gone down a storm...
I'd agree that tweaking the UI defaults is not generally a good idea
but that if you do, stick to the ones that are common (or at least always
likely to be present) across all L&F you might be running under. If you
want to see what UI defaults there are then I recommend Rob Camick's
utility for browsing them:

@Biagio - of course all your text fields will look the same when disabled,
so your problem is not limited to JDateChooser's text field....
