Integrating QML with C++ - Plugin problems [Solved]

NickGlynn

I don't have examples/declarative/cppextensions, I have:

C:\QtSDK\Examples\notificationexample
C:\QtSDK\Examples\4.7<loads of examples>

but even then the \declarative folder doesn't contain cppextensions:

I also can not find it in my QtSdk but look here:

I think we're getting off topic here.

The code accompanying the slides compiles fine - I just can't use it with QMLViewer so I wondered if the slides are wrong, the code is wrong (in which case, I need someone to contact to correct them ) or my configuration is wrong.

Has anyone managed to run qmlviewer on the ellipse9s.qml example?

dialingo

Yes, I have just downloaded and compiled the example. No problem at all. It runs like a charm.
I did not specify any path after qmlviewer. Make qml-cpp-integration/ex-extension-plugin/standalone your current directory and invoke
qmlviewer ellipse9s.qml

OK thanks for that - I guess something is wrong with my install on Windows. Going to reintall the Qt SDK :(

dialingo

I did not test it under Windows though.

I was aware it worked fine on Linux - that was the point of my posting, it didn't work under Windows so I wondered what was wrong. (hence the screenshot and the whole C:\ stuff).

Double sad face.

Ok, my mistake.
Just repeated the same thing under Windows. First issue: To build it the path should not contain blanks. Second issue: It does not work under Windows. I also did not find a dll .

Boom sussed it. For me I changed QtCreator to build for mingw of the whole project, then launching a mingw command prompt from Programs>Qt SDK>Desktop>Qt 4.7.3 for Desktop (MingW).

I could then navigate to the directory and launch qmlviewer to view the app.

I figured that it must be a compilation/library configuration issue about 20 minutes after blowing away my Qt install and starting a new one and reading dialingo's mention of the .dll file...

Good times. I think I'm well on the way for my Qt Accreditation ;)
