/* this is the result of hours of debugging: the following code
means that if we have a m_wxwindow and we set the size of
m_widget, m_widget (which is a GtkScrolledWindow) does NOT
automatically propagate its size down to its m_wxwindow,
which is its client area. therefore, we have to tell the
client area directly that it has to resize itself.
this will lead to that m_widget (GtkScrolledWindow) will
calculate how much size it needs for scrollbars etc and
it will then call XXX_size_allocate of its child, which
is m_wxwindow. m_wxwindow in turn will do the same with its
children and so on. problems can arise if this happens
before all the children have been realized as some widgets
stupidy need to be realized during XXX_size_allocate (e.g.
GtkNotebook) and they will segv if called otherwise. this
emergency is tested in gtk_myfixed_size_allocate. Normally
this shouldn't be needed and only gtk_widget_queue_resize()
should be enough to provoke a resize at the next appropriate
moment, but this seems to fail, e.g. when a wxNotebook contains
a wxSplitterWindow: the splitter window's children won't
show up properly resized then. */
