I caught myself saying “I’m learning Qt” the way I used to say “I’m learning PHP”. PHP is a language. Qt is not.
Qt is a framework (toolkit, platform - pick your slightly inaccurate word) for building applications, especially with C++. You write C++. You may also write QML. You use Qt’s modules: widgets, Quick, networking, and so on.
The distinction matters when you search for help. “How do I loop in Qt?” is a confused question. “How do I loop in C++?” or “How do I bind a list in QML?” are questions the internet can actually answer.
I am still learning both. I am trying to stop asking the toolkit to be a language.
