registerComboEvents

protected void registerComboEvents()

handleComboKeyStrokes

protected void handleComboKeyStrokes()

This routine will add the key handlers necessary for searching through combos by the key pressed (as Windows does, and as Swing does). This code really isn't too pretty, as SWT deactivates the key events if SWT.READ_ONLY is specified, so I have to handle that too, also you can't consume KeyEvents under a Combo (must be a bug), so I use a timer over the event pump to reset values. As I say, it's dirty but it works.
