Question

I have a C++ function that checks if Bluetooth is activated. I want to display a simple dialog telling the user to activate his Bluetooth and try again. As I have a QML interface this can be done through C++ or QML.

You can use the built-in information message box:

#include <QApplication>
#include <QDebug>
#include <QMessageBox>

int main(int argc, char *argv[]) {
    QApplication app(argc, argv);
    QMessageBox::information(0, "Try Again", "Please try to activate your Bluetooth again.");
}
