如何更改JComboBox的用户界面

Question

I like to change the UI of a JComboBox from the default metal look to some custom UI, see attached image.

I have tried changing all the UIDefaults for the JComboBox but to no success.

How does one achieve this?

Answer 1

You have to write your own ComboBoxUI class. I suggest to look at either Synth or Nimbus Look and Feel to make it easier.

Answer 2

您需要更改箭头图像，并在样式上为此JComboBox更改背景！

Answer 3

use WindowsLookAndFeel;

this works if and only if you are running your application in winows;

in your main you can do this before creating any UI:

try{
    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
}catch(Exception ignore){
}
