Unsolved Variable in a QRegularExpression?

[igor_stravinsky]

Is it possible to construct a QRegularExpression that includes a variable? I'm not seeing any examples.
e.g.

QString myVariable = "bar"
QRegularExpression re ("^foo.* myVariable$")

@igor_stravinsky what about constructing the pattern before and using setPattern() method to apply it? pseudo-code:

QString myVariable = "bar";
QString myPattern = "^foo.*" + myVariable + "$";
QRegularExpression re;
re.setPattern(myPattern);
