\section{\class{wxUpdateIterator}}\label{wxupdateiterator}

This class is used to iterate through all damaged regions of a window, within an OnPaint call.

To use it, construct an iterator object on the stack and loop through the
regions, testing the object and incrementing the iterator at the end of the loop.

See \helpref{wxScrolledWindow::OnPaint}{wxscrolledwindowonpaint} for an example of use.
