yes. Seel also WObject::sender()

Which compiler? gcc compiles this fine:
enum Foo {FOO_ONE, FOO_TWO};
...
WSignalMapper<Foo> *sm = new WSignalMapper<Foo>(root());
sm->mapConnect(_editor->clicked(), FOO_ONE);

I think the proper syntax would be
setJavaScript("function(s,e){myfunction();}");. No need to further
complicate such simple functions!
