This may be a slight rant but I am always struggling with remembering the
proper use of the layout builder AddGlue() function. It exhibits a totally
opposite behavior from real life glue, which is used to stick two things
together so they do not separate. AddGlue() does the opposite, adds an
expandable space layout item so the two things you stick the AddGlue() to can
move apart. It is probably too late to change, but can we deprecate
AddGlue() and replace it with something else like AddEmptySpace(),
AddWhiteSpace() or even AddNegativeSpace()?
"negative" space? What is that? :)
A nice thing about the BLayoutBuilder classes (where this is used) is
that they are template classes and almost completely inlined in the
places where they are used. So, we can change them without breaking the
ABI.
However, AddGlue has the advantage that it is short and easy to type.
Maybe a simple AddSpace or AddPadding would do?
I think some other UI toolkits call this a "filler", when it consist
mostly of empty space. Go figure :)
