\section{\class{wxSizerItem}}\label{wxsizeritem}
The wxSizerItem class is used to track the position, size and other
-attributes of each item managed by a \helpref{wxSizer}{wxsizer}. In
-normal usage user code should never need to deal directly with a
-wxSizerItem, but derived sizer classes will.
+attributes of each item managed by a \helpref{wxSizer}{wxsizer}. It is not
+usually necessary to use this class because the sizer elements can also be
+identified by their positions or window or sizer pointers but sometimes it may
+be more convenient to use it directly.

+Returns \true if this item is a window or a spacer and it is shown or if this
+item is a sizer and not all its elements are hidden. In other words, for sizer
+items, all of the child elements must be hidden for the sizer itself to be
+considered hidden.
