RE:Rounded Border

Posted by Kishori Sharan on August 17, 2000 at 1:24 PM

Hi Girish
You can have a rounded edge border for a button using SoftBevelBorder class . The syntax will be
your_button.setBorder ( new SoftBevelBorder ( BevelBorder.RAISED ) );
It does give a rounded edge border, but can be noticed only when you look at it carefully.If you are not satisfied with this then you can also create your own border. I have created a custom border KSoftBorder in the following example just to show you how to create a custom border. If you need a new one you can create own fancy borders...
Thanx
Kishori
