Hi guys,
I found code and read a bunch on the renderer stuff, but I still can't figure out how to change font.
This is what i have so far:
This changes the color depending on if the item on the row has severity A, B, C, D, etc.... How can I change whether to make a row bold dependinds on severity as well?
I have tried adding this adaptee.setFont(boldFont); to all the cases in the the switch statement, but nothing gets switched. Can someone help me?
Thanks,
