Forcing the scrollbars

I've got a wxFrame that includes a wxScrolledWindow.
The wxScrolledWindow's content is somewhat dynamic and
laid out with sizers.

When I change a child-component's size, I'd like the
scrollbars to appear automatically, but they don't. I
can tell that the wxScrolledWindow understands that it
needs scrollbars because as soon as I start to resize
the wxFrame, they appear and work just fine.

I know when I'm adding content, but how do I tell the
wxScrolledWindow to re-evaluate whether it needs
scrollbars to be visible or not?

Many thanks,

Gre7g
