wxHelpControllerHelpProvider is an implementation of wxHelpProvider which supports
both context identifiers and plain text help strings. If the help text is an integer,
it is passed to wxHelpController::DisplayContextPopup. Otherwise, it shows the string
in a tooltip as per wxSimpleHelpProvider. If you use this with a wxCHMHelpController instance
on windows, it will use the native style of tip window instead of \helpref{wxTipWindow}{wxtipwindow}.

You can use the convenience function {\bf wxContextId} to convert an integer context
id to a string for passing to \helpref{wxWindow::SetHelpText}{wxwindowsethelptext}.

should be deleted separately.
