Hi and welcome to devnet, For the how: create an instance of that class and connect as described in the documentation. That said, there's nothing wrong in having slots in your QMainWindow subclass. Just beware of not making it a god class that does anything and everything in your application. You must take the time to create a sane architecture for your application.

@Pedro said in Forum Updated NodeBB v4.3 + New features: Profile View Now you get a profilecard snippet by hovering over a user's name/picture. * Only if logged in. (Which probably makes sense, but I just thought I'd point it out. ....After logging in to get the feature working.)

In QT Design Studio, Tab Buttons are mostly for navigation within the UI, but each tab doesn’t automatically hide other content. Usually, a StackView or Loader is needed to switch visible content depending on the active tab.

@IamSumit can you reproduce the issue and share the Support Information logs. Please refer to the following Knowledge Base Article regarding how to obtain the Support Information is https://qatools.knowledgebase.qt.io/misc/collecting-support-info/collecting-support-information-linux-mac-windows/

LGTM. I just compared it to my checklist for CMake best practices (which you can read here), and I applaud you for: using subdirectories using PRIVATE (to limit scope) using functions that begin with target_ (in place of ancient/legacy habits of setting various options in a more global way)

I do a lot of python/pyqt database access using psycopg2 for PostgreSQL. It's so much easier to prototype these kinds of ideas in a language like python, and if needed then port it to c++, but truth be told, most of the time the python app is just works as is so no need to rewrite in c++. For something as simple as you are alluding to, the hard core OO models using DAO/DTO are probably overkill. Also, when dealing qith SQL queries it's "nice" to work in a language that is NOT strongly typed. Sorry if this is a round-about way to respond. Your path has merit in the realm of intellectual curiosity, but if you want it done quickly then python is a better option, and you can still wrap it in a Qt GUI. Yikes! Didn't notice OP was 9 months ago...

Hi, I think you can use https://forum.qt.io/category/5/qt-io-webservices category for this type of question (moved there by the way). Are these in your "unread" section ? Are they marked as you following them ?
