JButton.setEnabled(false) doesn't show as greyed off

[dtqui]

Hi,

I have this menu with consist of several JButtons which contains ImageIcon to represent them.

At a click of any of the buttons, the respective screens will show and the menu buttons will be disabled.

However, the behaviour of my menu disabling buttons is weird, sometimes it disable all, sometimes, a few of them only. Another weird thing is, the buttons are actually disabled(i can't click on it) but the image is still shown as enabled.

Anyone came across this?

Is it just a problem with the screen not being redrawn? Do you have to explicitly call paint() or refresh() or something?

You could always switch the text of the button using an HTML formatted string to be greyed out:
<font color=grey>Button Text</font>

It should grey out on it's own if you setEnabled(false); ... But I've had this problem a couple of times as well.

I think, if you use Images in menues, there is no method, to render them greyed out automatically.
You have to create the images used to mean 'diabled' on your own...

Hi all,

I've solved the problem, thanks to stevexff. I just added a repaint() after I disabled the buttons.

jstreich, I think you misunderstood. It's pure image on the button which didn't get greyed off, not the text.

stefanwagner, according to Java Tutorial at

http://java.sun.com/docs/books/tutorial/uiswing/components/button.html

the buttons can be disabled using setEnabled(false).

Thanks for replying.
