Cannot get QWebEngine to log to a remote console via port 9222.

Apparently QWebEngine is supposed to send debugging information, including console log messages to a remote debugger connected via http://localhost:9222.

After many tries we are unable to make this work.

qputenv("QTWEBENGINE_REMOTE_DEBUGGING", "9222");
qputenv("QTWEBENGINE_REMOTE_ALLOW_ORIGINS", "*");
...
QLoggingCategory::setFilterRules(QStringLiteral("js=true\nqt.webengine.webchannel=true"));
...
class DebugWebEnginePage : public QWebEnginePage
{
Q_OBJECT
public:
explicit DebugWebEnginePage(QObject *parent = nullptr) : QWebEnginePage(parent) {}

// NOTE: NOT overriding javaScriptConsoleMessage()
// so that console output goes to Chrome DevTools
};



int main(int argc, char *argv[])
{
// Step 1: Enable remote debugging BEFORE QApplication
qputenv("QTWEBENGINE_REMOTE_DEBUGGING", "9222");
qputenv("QTWEBENGINE_REMOTE_ALLOW_ORIGINS", "*");

QApplication app(argc, argv);

// Step 2: Enable JavaScript console logging AFTER QApplication
QLoggingCategory::setFilterRules(QStringLiteral("js=true"));

// Step 3: Create the widget/window
MarkdownEditorWindow window;
window.show();

return app.exec();
}


What are we missing to make this work ?

Thanks

Vertical Centering Counts Taskbar Size Too

void MainWindow::changeSize(QSize newSize)

{

resize(newSize);

QScreen *screen = QGuiApplication::primaryScreen();

QRect available = screen->availableGeometry();

int x = available.x() + (available.width() - width()) / 2;

int y = available.y() + (available.height() - height()) / 2;

move(x, y);

}

This is my slot to resize and center window, but the vertical centering counts taskbar size which I want to exclude. Thanks
