Re: [xmlvm-users] java.awt.Color and family

[Wolfgang K. <wol...@xm...>]

The only features a UIButton supports right now is creation, setting its
title and to register an event handler. Especially all the color stuff
you mentioned is currently not supported. What you saw in the Java
version of UIButton (these methods based on java.awt.Color) are only
used inside our Java emulator to create a UIAlertView with properly
colored buttons. This Java implementation should be fixed as soon as we
support color operations based in UIColor. And thanks for mentioning the
UIButtonTest. Since this uses the java.awt.Color based methods it cannot
be cross-compiled. I think we should remove that from the repository to
avoid confusion.

Coming to the String question. I lately noticed that the
java_lang_String implementation is based on NSMutableString. This should
be fixed since in Java strings are immutable. That's one thing I have on
my list - but not with highest priority.
