I am trying to set the background color of a worksheet tab using Apache POI. I can\'t seem to figure out how to set the style on the tabs themselves though.

Thanks f

Answer 1

As commented by Piotr,
to color tabs in POI 3.11 i had to use:

import org.apache.poi.ss.usermodel.IndexedColors;
sheet.setTabColor(IndexedColors.BLACK.getIndex());

(Note that it is "IndexedColors", not "IndexedColor" like showed by Piotr.)
here is a list showing the colors: http://jlcon.iteye.com/blog/1122538

It would appear that it is not possible. boo. This was the best explanation of why:

Answer 3

As commented by Alfabravo... it's possible now to change the XSSFSheet tab color.

sheet.setTabColor(int colorIndex) 

is used for that, and so if we use

 sheet.setTabColor(num);

• num = 0 : set Black Color in tab.

• num = 1 : set White Color in tab.

• num = 2 : set Red Color in tab.

• num = 3 : set Green Color in tab.

• num = 4 : set Blue Color in tab.

• num = 5 : set Yellow Color in tab.

and so on.
