Qt5 Documentation: qch Files

Question

I want to see the Qt help documentation inside QtAssistant, but the Qt5 installation did not include the .qch documentation files for the Qt libraries.

I tried to find them at http://qt-project.org , but could not find them anywhere. How to get Qt5 documentation files?

I am using Ubuntu 12.10, I installed the new sdk qd library from the qt-project site.

Answer 1

Open Assistant ( 5.0.1/gcc/bin/assistant ), and then go to Edit → Preferences .

There is a Documentation tab. If the list is empty, add the .qch files found in the 5.0.1/gcc/doc/ directory.

This is how it looks. This is also Ubuntu 12.10. Qt 5.0.1 is installed with the package qt-linux-opensource-5.0.1-x86-offline.run (388Mb).

Answer 2

Yes, the official Ubuntu documentation for Qt5 is very incomplete. You have no information about almost any class.

If you want to use the QtCreator / QtAssistant assembly from Ubuntu, you need to purchase the documents yourself. I made and downloaded them in my personal Mega account. Here are the docs . I installed the Qt platform with the installer from qt-project.org, took the documentation and put it into the software version.

I do not use QtAssistant as a standalone program, but integrated into QtCreator. To add documents to QtCreator, go to Tools> Options> Help> Documentation and click Add. Then select all .qch files, click "Apply" and enjoy. Perhaps try the method as above.

In the end, you can simply download the required * .deb file from the Ubuntu package repository and install it on your system. As they write here , this package will install * .qch files in /usr/share/qt5/doc . The trap is that you will need to remember that you did this, since your Ubuntu will not take any records.
