env: ubuntu 8.04 jdk1.6.0
this is a checkbox list ctrl for developer java swing application.
it is very simple. you only require implements a method!
require apache commons-lang.jar
For example:
langList = new CheckboxList(ts){
@Override
public Object getDataLabel(Object data){
Book a = (Book)data;
return a.getTitle();
}
};
centerPane.add(langList, BorderLayout.CENTER);
ArrayList as = langList.getSelectedData();
the ts is a Object array that your checkboxlist model.
you will implements the getDataLabel method.
get user's chooser is simple, only invoke langList.getSelectedData()
