QMenuBar is not a Win32 native menu bar, and neither is QMenu backed by a native win32 menu. Windows knows nothing about their role in the UI (unless it asks for it via accessibility infrastructure, but that’s unrelated to those messages).

So in my QMainWindow derived class, i override the nativeEvent() method, like so: bool QBrowserWindow::nativeEvent( const QByteArray& eventType, void *messageP, qintptr *resultP) { bool handledB(false); if (eventType == kWindowsEventType_GENERIC) { MSG& msg(*(MSG *)messageP); switch (msg.message) { default: { // nothing else } break; case WM_ENTERMENULOOP: { Log("start menu browsing"); SuspendTableUpdates(true); } break; case WM_EXITMENULOOP: { Log("end menu browsing"); SuspendTableUpdates(false); } break; } } return handledB; } However, those messages are never sent :( Any idea why not? -dave
