如何为SWT组合中的单个项目设置不同的颜色

Question

I have a Combo dropdown in SWT and have been thinking of setting different colors to different items in my list based on some conditions. I'll decide later (ie if the String has over 5 characters the item should have a red background otherwise it should be green)

I managed to change the background of the whole Combo widget but have noticed no method to change the background for its individual items.

Color colorGreenSWT = new Color(null, 0, 255, 0);
Combo combo = new Combo(comp, SWT.DROP_DOWN);
String[] languages = { "i", "it", "item", "items", "more_items" };
for (int i = 0; i < languages.length; i++)
    combo.add(languages[i]);
combo.setBackground(colorGreenSWT);

So is there any method to select the background color for each item in part?

Combo does not allow that. The Nebula project has a TableCombo Widget [1] that might interest you. Also SWT has an extended custom combo called CCombo that you might want to look at [2].
