hi
i have a list of bool

QList<bool> check;

how can i check all items is true?

I'd go with std::all_of.

@ARASHz4 usually by iterating over your list and checking.

luckilyfor you, QList has a predefined function that will do exactly what you want it to, without doing anyting yourself.

bool QList::contains(const T &value) const

QList<bool> check;
bool alltrue = !check.contains(false);

std::all_of(check.constBegin(),check.constEnd(),[](bool val){return val;});
