Hello, Sebastian
I've fixed that bug. My mistake was that I didn't implement 2 methods of the
*Impl class: computeChildBoxWidth and computeChildBoxHeight. Now I made them
and all seems to be OK.
A couple of words about my layout. It is pretty much like DockLayout (i.e. it
does need to manually inform the children about their dimension/location). It
is not allowed for children to define any dimension/location properties (like
DockLayout does on add() method). So it seems to me that I did it right. But
if you think that their could be some problems with my implementation please
let me know.
Thanks,
Alexei Golovko
