wx2.8.4-mac Disappearing scroll bars

[Matt Connolly]

I'm using "wxHSCROLL | wxALWAYS_SHOW_SB" (I'm after horizontal  
scrolling to represent a time axis).

The flag "wxALWAYS_SHOW_SB" is commented as "this style is only  
supported by wxUniversal and wxMSW so far".

What I want to do is set the virtual size to a size where the height  
is the same as scrollWin->GetClientSize().y ... except that this  
changes depending on whether or not the scroll bar is visible, which  
of course changes based on how big the time axis is (ie: does the  
virtual size width fit in the window, which of course changes if the  
user resizes the window).

So I can't seem to determine the correct height of the virtual size  
because it depends on the width (and the actual visible width of the  
scrolling window). I want the view to be flexible horizontally and  
fill the window vertically with the same height as the scrollwindow.

It's all so much simpler when the scroll bar is always there.
