Notice in C# to add a callback to an event, we use the following syntax: /* Connect the "clicked" signal of the button to our callback */ button.Clicked += new EventHandler (callback);In Java it is: checkButton1.addListener(new ToggleListener() { public void toggleEvent(ToggleEvent event) { if (checkButton1.getState()) checkButton3.setSensitive(false); else checkButton3.setSensitive(true); } });
FWIW, this illustrates why Java frequently turns out verbose. ("Noun-orientedness" is not it.) In Java it is necessary to assign a name to concepts that need no name at all in more dynamic languages. Here addListener is replaced with an operator in C#, ToggleListener is represented by the function signature, and the use of the ToggleEvent is probably optional. The current Java model frequently requires the programmer to express things in an awkward way compared with other languages.
However, with Sun's Java implementation going GPL, there's finally hope for solving this stuff. Coders who want to improve Java no longer have to feel like they're working for Sun without wages; now they can be part of the established free software community and work toward a common good. Very cool.
