public boolean toggleBreakpoint(Context context,
This method does nothing, but returns true to the caller indicating that we've
fully handled the click. This effectively disables setting of breakpoints in the
node class this handler is bound to. Useful for disabling breakpoints in text
files or other file types that don't have breakpoint support, or types such as
some XML files that require breakpoints be set via design view and not through
the editor source view.
