Hiding context button in Qt 5.15

Dummie1138

Hi. I'm building a QInputDialog in Qt 5.15, and have the following code.

    QInputDialog passwordBox(this, Qt::Dialog);
    bool ok;
    passwordBox.exec();

I would like to remove the context help button, aka the "?" button and am unsure how to do so. The Qt 5.15 documentation for QInputDialog doesn't have any suggestions, and I attempted the following based on the application attribute documentation.

    QInputDialog passwordBox(this, Qt::Dialog);
    bool ok;
    passwordBox.setAttribute(Qt::AA_DisableWindowContextHelpButton);
    passwordBox.exec();

I got the following error.
error: cannot initialize a parameter of type 'Qt::WidgetAttribute' with an rvalue of type 'Qt::ApplicationAttribute'

I am unsure how to proceed on hiding the context button. Please let me know if more info is required.

Qt::AA_DisableWindowContextHelpButton is to disable it application-wide, to be used on the QApplication object. If you want it only on this dialog try removing Qt::WindowContextHelpButtonHint instead? Something like:

passwordBox.setAttribute(Qt::WindowContextHelpButtonHint, false);
