If that is something like
"std::vector of length 3, capacity 4 = {0, 1, 2}"
then you see the result of gdb's (or libstdc++'s...) pretty printers,
not the result of Qt Creator's.
This is not the default setup.

Putting
def qdump__Std__Vector(d, value):
qdump__std__vector(d, value)
in stdtypes.py should work if qdump__std__vector works (i.e. in the default
setup)
You can try putting your function in there for starters. For other locations,
it depends on your exact setup.

Feel free to.
