--- Comment #1 from Lamarque V. Souza <lamar...@kde.org> --- Hi, MMQt API is assynchronous and MMQt needs to receive signals from ModemManager to update the message list. That is probably not happening because you are doing everything in synchronous mode. Try adding the line below after *before* step 7 and check if your example works: // Include QCoreApplication if compiler complains about qApp not defined. qApp->processEvents(); That will make Qt process any pending event (like ModemManager's signal to update the message list). If that works then you need to update your code to work in asynchronous mode. Using processEvent() must be avoided since it is a costly method call. -- You are receiving this mail because: You are watching all bug changes.
