avoid deprecated QFlags<T>::QFlags(QFlags<T>::Zero) constructor * Vt102Emulation.cpp (Vt102Emulation::getErase): In call to KeyboardTranslator::findEntry, use Qt::NoModifier instead of passing nullptr for modifiers and use default instead of passing nullptr for state argument. * dialog.cc (MessageDialog::MessageDialog): Use defaults instead of passing nullptr for QMessageBox buttons and parent arguments. * documentation.cc (documentation::find): Don't initialize find_flags with 0 value.
