Java Forum / GUI / May 2005Giving 2d shapes a raised appearance
Hi, Is there a simple means of giving a java.awt.Rectangle a raised or 3D appearance? Cheers! > Is there a simple means of giving a java.awt.Rectangle a raised or 3D > appearance? If you can live with a sometimes cheap looking shadow effect, then draw two rectangles of the same size, but with a slight x and y offset (e.g. 5, 5 pixels offset) of the the origin. E.g. give both rectangles a black border, but fill the first (lower) rectangle with black, and fill the second (upper) rectangle with white. /Thomas  SignatureThe comp.lang.java.gui FAQ: ftp://ftp.cs.uu.nl/pub/NEWS.ANSWERS/computer-lang/java/gui/faq Beveled border http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/BorderFactory.html > Is there a simple means of giving a java.awt.Rectangle a raised or 3D > appearance? Have you tried giving it a RaisedBevelBorder? SignatureRegards, John McGrath > Have you tried giving it a RaisedBevelBorder? Borders are intended for Component decoration. Rectangle, however, is basically a Shape. You can abuse most Border implementations and convince them to paint on an arbitrary location on some JPanel's Graphics2D context. You have to provide some fake Component. However, this usually only works, because the Border implementations don't interact much with the Component. But this is an implementation details, and Sun might at any point in time decide to do things differently. Therefore I wouldn't use a Border. Instead I would paint the two to three lines per side myself. /Thomas SignatureThe comp.lang.java.gui FAQ: ftp://ftp.cs.uu.nl/pub/NEWS.ANSWERS/computer-lang/java/gui/faq > > Have you tried giving it a RaisedBevelBorder? > > Borders are intended for Component decoration. Rectangle, however, is > basically a Shape. Yes, I did not read the question carefully and I was thinking he was talking about a component, not a Shape. Still, I would recommend looking at a raised BevelBorder and other Border classes to find one that provides the desired effect, and then look at the source code to see how to implement the effect.

That works, but not very well, IMO. The Graphics context only contains a single color, so the draw/fill 3D operations need to derive multiple colors from the current color using operations like the Color darker() and brighter() methods. I find it works much better if you choose the colors yourself and draw the individual lines. SignatureRegards, John McGrath Free MagazinesGet these publications absolutely FREE for up to 12 months.
