+ @section overview_exceptions_strategies Strategies for exceptions handling
+
  There are several choice for using the exceptions in wxWidgets programs. First
  of all, you may not use them at all. As stated above, the library doesn't throw
  any exceptions by itself and so you don't have to worry about exceptions at all
  unless your own code throws them. This is, of course, the simplest solution but
  may be not the best one to deal with all possible errors.
+
  Another strategy is to use exceptions only to signal truly fatal errors. In
  this case you probably don't expect to recover from them and the default
  behaviour -- to simply terminate the program -- may be appropriate. If it is
- not, you may override #OnUnhandledException() 
+ not, you may override wxApp::OnUnhandledException()
  in your wxApp-derived class to perform any clean up tasks. Note, however, that
  any information about the exact exception type is lost when this function is
- called, so if you need you should override #OnRun() and
+ called, so if you need you should override wxApp::OnRun() and
  add a try/catch clause around the call of the base class version. This would
  allow you to catch any exceptions generated during the execution of the main
  event loop. To deal with the exceptions which may arise during the program
- startup and/or shutdown you should insert try/catch clauses in 
- #OnInit() and/or #OnExit() as well.

  Finally, you may also want to continue running even when certain exceptions
  occur. If all of your exceptions may happen only in the event handlers of a
  single class (or only in the classes derived from it), you may centralize your

  the wxApp::HandleEvent() which allows you to handle
  all the exceptions thrown by any event handler.
