WxListCtrl refresh issues

[Cees De Groot]

Hi,

I've noticed that (virtual) list controls have trouble refreshing.
More specifically, there are two places in my project where refreshing
doesn't work:
- When another window (modal dialog, for example) is moved over the
list, the contents of the list are erased where the dialog has been;
- In some circumstances, when I pop up a window with a listctrl and
programmatically fill it (through #setItemCount:).
In both cases, moving the window containing the affected list
refreshes it again. I'm not sure whether this is a Wx-level,
WxSqueak-level, or programmatic error (by me), but I find it hard to
believe my code can cause this...

(haven't gotten around retrying the XRC issue with the subclassing - I
wanted to finish the widget and the panel thing worked nicely, so I
left it until after I get back from summer camp)

Regards,

Cees
