Hi Roger,
A key point is that the Grid manages itself its available space 
according to the size it can have.
If you just tried to create a simple grid within a simple frame, you 
probably got a grid filling all the frame space, and it's what you want. 
Why that ?
If you do it (for instance with the script below), and you try to 
manually reduce/increase the size of the window, you should see 
scrollbars at the edge of the window ; these scrollbars come from the 
grid, because they take in account the labels row and col (wxGrid comes 
from wxScrolledWindow). You can see that no more space is available 
beyond the scrollbar, so the grid takes the whole space.
And why the white space on the right ? This space is not on the right of 
the grid, but on the right of the last col. We could think it's like 
that because it's not possible to compute an appropriate col size for 
the grid cols, but it's not displayed exactly the same in linux and in 
windows. In one case it's over the last col (not enough space) and in 
the other case it's beyond (too much space). I think that as the program 
must work on all the environments, the interface must stay enough 
global, and sometimes the display is not perfectly done.
The advantage is that if we let wx decide, we won't have to think how to 
set the widgets.
