-/** Store a function object and execute it asynchronous.
-
- The features of this class are:
- a) It provides a wrapper around a VCL Timer so that generic function
- objects can be used.
- b) When more than one function objects are posted to be executed later
- then the pending ones are erased and only the last one will actually be
- executed.
-
- Use this class like this:
- aInstanceOfAsynchronousCall.Post(
- ::boost::bind(
- ::std::mem_fun(&DrawViewShell::SwitchPage),
- pDrawViewShell,
- 11));
