- Only generic implementation of this class exists currently but it is
- planned to provide a native GTK+-based version in future wxWidgets releases
- so avoid the use of the methods marked "generic only" for maximal
- portability.
+ Currently this class is implemented generically (i.e. in the same
+ platform-independent way for all ports) and also natively in wxGTK but the
+ native implementation requires a recent -- as of this writing -- GTK+ 2.18
+ version.

+ that the extra buttons already allow the user to close it.
+
+ Clicking the button will generate a normal EVT_COMMAND_BUTTON_CLICKED
+ event which can be handled as usual. The default handler in wxInfoBar
+ itself closes the window whenever a button in it is clicked so if you
+ wish the info bar to be hidden when the button is clicked, simply call
+ @c event.Skip() in the button handler to let the base class handler do
+ it (calling Dismiss() explicitly works too, of course). On the other
+ hand, if you don't skip the event, the info bar will remain opened so
+ make sure to do it for at least some buttons to allow the user to close
+ it.

+ Notice that the generic wxInfoBar implementation handles the button
+ events itself and so they are not propagated to the info bar parent and
+ you need to either inherit from wxInfoBar and handle them in your
+ derived class or use wxEvtHandler::Connect(), as is done in the dialogs
+ sample, to handle the button events in the parent frame.
