RE: custom border

Hi,

It is indeed possible to create a custom border.

Please see the snippet at the end of this mail. The snippet is meant for ULC
6.1.

Moreover, please refer to ULC 6.1's ULC Extension Guide before you implement
your own extension.

I hope this helps.

Thanks and regards,

Janak

Subject: custom border



Hi all,

Is it possible to create custom borders in ulc by extending ULCAbstract
border.  I have a ULCTable and I have used a custom cell renderer to draw
borders around multiple cells using ULCMatteBorder, but I would like to
specify a custom color for the top, left, right, and bottom of the border.

Thanks for your help,
