how can i change color of disabled jcombox

[RichersooN]

Hi is there any way to change default color when JComboBox is setEnabled false?


I used Nimbus Look and feel.. It seems that it doesnt fit my design the default color of grey when it is disabled... how can I change the default color of disabled JComboBox?

Try setBackground(Color). If that doesn't work, then you can't :/

setBackground(Color) didn't work.. It's just a simple color manipulation, why java can't:mad:

Java can but that requires you to specify your own look and feel in Swing. If you really need to change this color, I suggest subclassing the appropriate Nimbus ComboBoxUI implementation and using your own painting. But I have never done this so I'm not sure which class exactly to subclass and what methods to use and override. :/

Do you know how to override the JComboBox when it is click it doesn't anything

Have you tried using the UIManager to change the default colors? Something like:

Color newColor = new Color(250, 50, 50);  // or whatever color you want
UIManager.put("ComboBox.disabledBackground", newColor);

For more on this, please see this section of Rob Camick's excellent blog: uimanager-defaults

@Fubarable
That's pretty useful.

Did you try this method: public void enableInputMethods(boolean enable)? It's a method in the Component class (A JComboBox extends from that class).

How would that allow the changing of the color of JComboBox?

The component isn't completely disabled so you are able to set its foreground and background colours (as if it were completely enabled).

It won't let you change the color if it is disabled?? :eek:

Well, according to the OP and the L&F, nope; so my suggestion was to make the component act like it was disabled while it was still enabled (so the colours could be changed).

I just played around with JComboBox; it changes the background color normally enabled and disabled.

This works for me.

box.setBackground(Color.blue);
box.setEnabled(false);

The combo is made up of a textfield (or label) and a button. You need to find out how to access the textfield inside the combo.

Have you tried accessing the components inside the combo box? Changing the editor or renderer?

I refuse to believe it is not possible to do without Look and Feel.

this does not work and I'm suprised that it seems to be working for you, are you sure the background wasn't already blue?
I searched many forums for an answer to this as I had no luck with standard setForeground methods etc and changing the UImanager either as .put or getDefaults().put did not work.
the only solution I found that worked - and it's quite simple was

((JTextField) comboBox.getEditor().getEditorComponent()).setDisa bledTextColor(Color.#####);

apparently this is only supposed to work for enabled boxes but it worked for my disabled boxes perfectly and can be done befoer or after the box enabled is set to false

i can see from the time stamps that you most likely don't need or care about this anymore but thought I'd post it to make it easier for anyone else searching for a solution
