Re: FlexTable RowSpan problem
Maybe this is a misunderstanding on my part then. When I insert at (0,0) with colspan="2", then I was expecting that a subsequent insert at (0, 2) would be the next cell over. HoweverFlexTable sticks an empty cell in between, resulting in 3 cells existing in the table rather than 2, which is what I expected. In html terms, if I write ..., is the index of td xyz 0,1 or 0,2? I was assuming it's at grid position 0,2. If I'm wrong, then the documentation is confusing because there are two meanings of "column", one for indexing the table and one for spanning. Ivan...

Re: FlexTable RowSpan problem
Hi, I've recently experienced similar bugs in FlexTable and had to work around it by next my tables and never using colSpan.

Re: Obtaining the click position of the underlying widget from an overlay widget
I believe you want this:
int x = event.getRelativeX(event.getRelativeElement());
int y = event.getRelativeY(event.getRelativeElement());

Re: why does DockLayoutPanel care about the order of its elements?
DockLayoutPanel assumes that "center" is all the space that wasn't taken up
by a component that was added to the north, east, etc. There's a built in
assumption that when you call add() you have finished adding any components
that will be docked to an edge.
