[Qt-qml] QML Quick examples : "Charts 1.0 module" : how this works?

[Matthieu.Rioteau at skf.com]

Hi,

I finally succeed in making "chapter6" to run. The solution was simple but 
not obvious.
Actually, to run .qml files, Qt Creator uses an appli called 
"qmlobserver.exe", that seems to not deal with plugins very well.
I changed the QML appli and take the one called "qmlviewer.exe" that is 
inside Qt SDK, and everything works fine now.

So a new question has come up. What are the differences between 
qmlobserver and qmlviewer (especially in terms of features) ?
Could somebody give details on that ?

Thanks in advance, and anyway thanks a lot for already very helpful 
answers ! ;-)

Matthieu

The Chapter 6 project is a C++ plugin rather than an application. 

To run the example, you'll need to build the C++ plugin first, and then 
open app.qml with the QMLViewer application.

If you are using Qt Creator, I'm not sure how it handles a project with 
mixed plugin & QML files, but you should be able to at least use it for 
the first step of building the C++ plugin, if you import it as a project.

I'm not sure what you mean here. The chapter6-plugins/app.qml file does 
not contain an "import Charts 1.0" line, and it shouldn't have one, since 
the qmldir file is in the same directory. The projects for the other 
chapters do contain this line, because they are C++ application projects 
rather than plugins.
