Re: [platform-swt-dev] ordering problem adding buttons to a GridLayout

1) Post Code
2) Don't use setParent() - it doesn't
work on every platform.  Just pass in the parent.
3) Use moveAbove() to change the Z-order
to be the order you want or reverse the calls to setParent().

Why does this have to be done?

I have a weird layout problem that I cannot quite
figure out.  I am creating
a simple Shell s that has a GridLayout with 2 columns.  I am then
creating 2
buttons, b1 and b2.  However, when I create those buttons, I use a
Composite
other than the aforementioned Shell as the parent argument to its
constructor. (something that unfortunately has to be done because SWT
widgets have no default constructor).  After creating the buttons,
I set
their layout data (which is nothing more than a GridData object with
GridData.FILL_BOTH).  I then invoke the setParent(s); method on both
b1 and
b2 to make s the parent, and then open the Shell.

Here's the weird thing: b1, which was added first to the Shell (s), displays
on the right, while b2 displays on the left.  The doc says that components
in a GridLayout are laid out from left to right, but this would suggest
right to left.  Any ideas on the problem?
