With the latest devel-1-0 CVS this doesn't work:

#include "pgapplication.h"
#include "pglistbox.h"

int main()
{
        PG_Application app;
        app.LoadTheme("default");
        app.InitScreen(640, 480, 16, SDL_SWSURFACE);
        app.SetEmergencyQuit(true);

        PG_ListBox l(NULL, PG_Rect(0,0,400,400));
        PG_ListBoxItem *p = new PG_ListBoxItem(20, "test");

        l.AddItem(p);
        l.RemoveAll();
        l.AddItem(p);
        l.Show();

        app.Run();
        return 0;
}

The item isn't displayed.

BTW, is there any API documentation (other than automatically generated)
which I could use? I mean, it's not easy to determine what exactly a given 
function
does (function names are fairly descriptive, though) and I'd really like to 
understand the internals.
