  Hello @supot. Squish for Qt only exposes "public" APIs. You must declare the desired slots public. As a test I added... public slots: int GetColorCode(); QString GetRGBColorCode(); ...to squish_dir/examples/qt/addressbook/mainwindow.h, and... int MainWindow::GetColorCode() { return 3; } QString MainWindow::GetRGBColorCode() { return QString("3"); } ...to squish_dir/examples/qt/addressbook/mainwindow.cpp, compiled the example and loaded it in Squish. Afterwards the "Methods" view showed these two methods when selecting the MainWindow object in the "Application Objects" view. Regards Clemens

  There is not much information to go by to find out your real problem. Nevertheless, there are two things that come to mind: If your application is multithreaded you should note that GUI calls have to be managed within the GUI thread. This means that if your exception is caught in a different thread you cannot directly call showMessage(). Doing so will (or at least might) crash your app. You don't show the code inside the try block. Maybe you have wrong expectations about the use of signals/slots together with exceptions. Exceptions inside the slots cannot be safely handled outside the slot. You can try to put a try/catch around the main event loop. This will show if the exceptions take a path you don't expect. Here the catch block cannot use the GUI anymore because there is no functioning GUI left once you are outside the main event loop. If you are coming from a managed language you should maybe think about changing your style when writing C++. There is an ongoing discussion in the C++ community about how to handle errors properly. So far, the only thing (almost) everyone agrees on is that exceptions should only be use for exceptional behavior and not for error handling. If, e.g., a file cannot be found this is expected and not exceptional. There are only very few places in C++ where exceptions are thrown, like out-of-memory or dynamic cast on a reference. The likeliest reason why you want to catch exceptions is that you throw them yourself. Then you should maybe look for other ways to report and handle errors. Exceptions don't play nice with the asynchronous nature of signals and slots.

  Is there an issue with the installer? Using qt-unified-macOS-x64-4.2.0-online.app I tried last night installing and while downloading it seemed to stall at 33%. I left it overnight and it was still stuck, so closed, restarted the installer and restarted the process. Connects to my account, accept licence and then it goes to download meta data and times out. Anybody else seen this? I saw a post back in January 21 that the backend server was down for a day, but not seen anything today. No idea how to raise this to support. Want to trial the product, but it does not even install ! No obvious contact. Is this even the right forum for installer issues? Edit: I have closed, restarted, deleted the installer, redownloaded and nothing. Same things. I expect the initial installer that failed at 33% has hidden files that are still dangling as it remembers my login on restarting the installer even after deleting what I can find.
