\section{\class{wxUpdateIterator}}\label{wxupdateiterator}
|
|
|
|
This class is used to iterate through all damaged regions of a canvas, panel
|
|
or dialog box, 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.
