I want JCheckBox Disabled color to be black. Any workaround ?

Hi,
I have JCheckBox and other components in a panel and I will print the panel. Before printing I will disable the JCheckBox and will show the user. After disabling, the JCheckBox Forground color is Gray and if i print it, it is hardly visible. Is it possible to change the fore ground color of the JCheckBox to Black for printing ??

Any suggestion or workaround is welcome.

Regards,
Prem.

YourCheckBox.setForeground(yourColor);
Will work even if is disabled.

Why are you disabling it?

Hi Ovi,
My code is like this:

boolean flag = ...; // i will read the data from a model
myCheckBox.setForeground( Color.black);
myCheckBox.setEnabled( flag);

But, still the check box is disabled and the color is gray and i am getting the same color in the hard copy.

Hi Objects,
I am reading the values from the model, so i am disabling the JCheckBox.

Regards,
Prem.

f you set the color other to the black before you disable'it you will see the difference.
The checkbox renderer only make a graphic filter on the foreground so a black foreground will become a less black one (gray) after the check box i disabled.

Still don't exactly inderstand your reason for disabling but why not use a glass pane instead of disabling the checkbox?

Ovi

boolean flag = ...; // i will read the data from a model
// myCheckBox.setForeground( Color.black);
myCheckBox.setEnabled( flag);
myCheckBox.setForeground(Color.blue); // or new Color(int, int, int);

If you want control of the disabled icon the you can explicitly set it using setDisabledIcon() setDisabledSelectedIcon() method:

eg.

cb.setDisabledIcon(cb.getIcon());
cb.setDisabledSelectedIcon(cb.getSelectedIcon());

will use the same icon when disabled as it does when it is enabled.

Is it possible to add a glassPane to a JPanel ??

Mick Barry

No but your frame will have one.

Mick Barry

No, you just use the one on your frame.

My parent component is Frame and not JFrame. So I think it is not possible to use Glass pane over my component.

Mick Barry

You could possibly switch to a JFrame.
Or define the disable icon you want to use as I suggested above.
Or find an alternative to disabling.

Your decision really :)

checkBox.setForeGround( color) won't work when the checkbox is disabled.

Mick Barry

Then simply assign the disabled icon that you want to use explicitly as I described above.
I believe it only greys out the icon, if you have not explicitly defined one.
