no 'help' plugin in Qt creator

[zbysiu100]

Hello,
I have ubuntu 19.04 64bits system, and my Qt creator 4.8.1 based on Qt 5.12.2 doesn't have a help documentation. There is an icon of 'help' , and when I click it, than a new window opens, but empty.
Would somebody help me please, to solve this problem?
Regards

Hi and welcome to devnet,

How did you install Qt and Qt Creator ?

[zbysiu100]

Hello,
I have installed from the console, from Muon program, not from the sources.

Do you mean you installed your distribution provided Qt Creator ? If so, you might also need to install the corresponding documentation package. The same goes for Qt, you need to install the development packages.

Hi,
I have just checked dev files in Muon sources, and there is 5 files already installed.
And what to do now?

What exactly did you install ?

@zbysiu100 With qt creator is everything fine, and it was my fault, because I did not operate the program correctly.

Glad you found out !

What were you doing wrong ?

[zbysiu100]

If I go in Qt to the /option/help/Documentation
And there is a window with filter named - "org/kde.NetworkManagerQt.5_56-0
But this is only one filter, no more filters.
For example if I wanna find information about Qfile, there is no information about this topic.
May be I wanna download from the internet?

Hello,
I have removed qt and installed a new one from sources, and now is great.
