} }

this code is correct? add number with background color Now i use 4 window with different background color

please give any other solution add background color?

Hi Is this picture a result of running your code? Looks good. What is the issue with the code?

[maxmurugan]

No issue just clarify background color code

[board707]

The code is generally correct. When you use a .setTextColor() with drawString(), only the second parameter (background) in the setTextColor is meaningful, since the text color is overwritten in the drawString(). When you use a setTextColor with marquee, both parameters matter, since the marquee does not have a separate color setting

thanks a lot
