This subdirectory contains a set of widgets which implement the layout behaviour of Java's LayoutManager classes. You can see them on the widget palette in the 'Java Widgets' section. This directory contains this file, and two directories: lib/ This directory contains the source files for the widgets themselves, a makefile so that you can build them, and a static library which contains a build of the widgets for your system. When building generated code which used the Java widgets, you need to ensure that this library is linked in (the default makefile does this for you). h/ This directory contains the header files for the widgets; these should be included in any files which use them. The generated code contains appropriate #include statements, of course.
