Ability to open a file at a line number

currently Qt Creator can open a file with an external command.
qtcreator -client /tmp/somefile.txt

However a with valgrind reports or error checking tools I normally have a line number too,

This would be useful to have gedit/vim style line number.
eg:
qtcreator -client /tmp/somefile.txt +67
or some apps do...
qtcreator -client /tmp/somefile.txt -goto 67

Im not fussed about how, but the functionality would be useful and probably not hard to add.
