warning: ‘Qt::DropAction QDrag::start(Qt::DropActions)’ is deprecated: Use QDrag::exec() instead [-Wdeprecated-declarations]
warning: ‘void QProcess::finished(int)’ is deprecated: Use QProcess::finished(int, QProcess::ExitStatus) instead [-Wdeprecated-declarations]
...
warning: ‘const QRect QDesktopWidget::availableGeometry(int) const’ is deprecated: Use QGuiApplication::screens() [-Wdeprecated-declarations]
...
warning: ‘const QBrush& QPalette::background() const’ is deprecated: Use QPalette::window() instead [-Wdeprecated-declarations]
...

...
warning: ‘void QTextOption::setTabStop(qreal)’ is deprecated [-Wdeprecated-declarations]
warning: ‘void QList<T>::swap(int, int) [with T = ProjectExplorer::BuildStep*]’ is deprecated: Use QList<T>::swapItemsAt() [-Wdeprecated-declarations]
warning: ‘void QProcess::setReadChannelMode(QProcess::ProcessChannelMode)’ is deprecated: Use QProcess::setProcessChannelMode() instead [-Wdeprecated-declarations]
...
