I have an application, I add a menu, then a toolbar with graphics - when I
then try to split up the remain shell area with sahform and griddata, i
end up with the sasform and gridlayout to right of the toolbar:

------------------------------------------------------------ ----
| Shell
| Menu1 menu2
| tool1 tool2 tool3 tool4 |----------------|------------|
| | sashform and griddata appears here

Obvious I need to reset the shell size to the orginal size - toolbar size
but how do I do this?

Could you please give a snippet of code of how you did this? The MenuBar
should be distinct and the toolbar should not be next to it.

I don't know where you got a menu from. The example you gave has no menu
in it.

However, the reason everything is flow out to one line is because you
gave the shell a FillLayout. The toolbar and SashForm are siblings on
the shell. Filllayout says to layout siblings all together on one row.

Your code looks like it was created through the VE, it is the VE style.
so I would suggest using the Ve to edit your code.

First thing is you want a GridLayout with one column for the Shell, not
a FillLayout. then you want the Toolbar to be first in the shell with
lahyout data that says Grab Excess Horizontal and Fill Horizontal. Then
you drop the SashForm with Fill Both, Grab Excess Vertical and Grab
Excess horizontal.
