This is a simple high level helper combining an arbitrary control showing multiple items with the buttons allowing to add items to and remove items from this control, but using the buttons and the layout appropriate for the current platform. Add the implementation itself, an example of using it to the dialogs sample and the documentation. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@78462 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
