Qt learning path (6): Use of API documentation

Let's talk about how to use the qt api documentation. Because QT has a commercial version, its documentation is sound and well written. For developers, one of the required courses for development when viewing documents-no one can remember the use of so many APIs!

It is very easy to view documents in QT. If you use qtcreator, the Help button on the left is the document viewing portal. If no, you can see the QT document in assistant.exe In the bind of the qtinstallation directory. In earlier versions, QT documents were published in HTML format. However, in version 2009.03, I did not find documents in HTML format. Maybe QT has changed all of them to binary format? -- Of course, if you have installed all the QT components, you can find the assistant in the Start menu! There are many items in the document in ASSISTANT: the first is help :-), the second is help of QT designer, and the third is help of QT linguist; the fourth is the help of qmake. The last is the qt api document, which is opened by default in qtcreator. However, the content of this document cannot be elaborated here, because the entire document is too large and I have not read much. It is often used for on-demand queries, it's like a dictionary-no one will be able to hold this dictionary every day, right? In addition, the documents here are all in English. However, it is helpful to know some English documents for development, isn't it?
