Subject: Emit rebuild_needed from a container when a child is added
X-Git-Url: http://git.tdb.fi/?p=libs%2Fgltk.git;a=commitdiff_plain;h=999cd0294889e5eecd61df18a697d2c55ed6c0d6

Emit rebuild_needed from a container when a child is added

Otherwise the flag won't properly propagate if the container itself is
already parented.
