Combobox backgroundcolor in Windows 7

Classic Servoy

Hi,

We use comboboxes with valuelists.

In WindowsXp the normal background is White and the disabled background is Grey.
So we used the following code to correct this

application.setUIProperty("ComboBox.disabledBackground", new Packages.javax.swing.plaf.ColorUIResource(java.awt.Color.WHITE));
application.setUIProperty("ComboBox.disabledForeground", new Packages.javax.swing.plaf.ColorUIResource(java.awt.Color.BLACK));

In Windows 7 the normal background color is grey and also the disabled background is grey.

The code

application.setUIProperty("ComboBox.disabledBackground", new Packages.javax.swing.plaf.ColorUIResource(java.awt.Color.WHITE));
application.setUIProperty("ComboBox.disabledForeground", new Packages.javax.swing.plaf.ColorUIResource(java.awt.Color.BLACK));

does not work.

I also tried

application.setUIProperty("ComboBox.background", new Packages.javax.swing.plaf.ColorUIResource(java.awt.Color.WHITE));
application.setUIProperty("ComboBox.foreground", new Packages.javax.swing.plaf.ColorUIResource(java.awt.Color.BLACK));

but that does also not work.

Any ideas to set the background color of a combobox ??

Regards,

Hans

yes backgrounds you can’t seem to set in windows 7. That just takes the look and feel of the system.

this does work:

application.setUIProperty(“ComboBox.disabledForeground”, new Packages.javax.swing.plaf.ColorUIResource(java.awt.Color.BLACK));

i can enable something that some part of the combobox is honoring the background but that makes it quite ugly:

thanks jcompagner, you have open my mind!

Starting from your reply, I’have found the solution for the problem.
You have to set the Look & Feel of the system for this element.

On SolutionOpen() function I’ve added this line

application.setUIProperty(“ComboBoxUI”, ‘com.sun.java.swing.plaf.motif.MotifComboBoxUI’);

You can also use this other L&F, but I prefer the first :D

application.setUIProperty(“ComboBoxUI”, ‘javax.swing.plaf.metal.MetalComboBoxUI’);

Finally I post this link:

It contains the settings for L&F in Java 1.5.0 and 1.6.0 (Windows + Mac + Linux).
