Harmattan Qt Components: "import com.nokia.meego 1.0" or "import com.meego 1.0" ?

awiese2007

I am getting the same error message when changing from "import com.meego 1.0" to "import com.nokia.meego 1.0"...the related lines of code are:

@ ToolIcon {
platformIconId: "toolbar-add";
onClicked: pageStack.push(Qt.resolvedUrl("AddPage.qml"));
}@

qgil

fwiw I'm using

@import com.meego 1.0

...

iconId: "toolbar-add"@

And yes, the hobbyist developer in me is also confused. :)

FWIW is ended up using only "import com.meego 1.0" and I forgot about this issue altogether. But it's still confusing.

I can guess this is related to the fact that the device has an older version of Qt Components (1.0) while we are looking at the source of QmlComponentsGallery that uses a newer version of it (1.1). It would be nice to get a comment from someone who knows what's going on, but I think we just have to wait for the final release of Harmattan SDK and an update for the N950 with Qt Components 1.1.

Both com.meego and com.nokia.meego work on the device, and AFAIK there is no difference between them functionality-wise. However, you cannot mix the two namespaces in one application: You have to use just one all over the place, otherwise you get runtime errors. (The problem seems to be that both directories contain a copy of the same C++ library, while only one library can be loaded at runtime.)

In the end we settled on com.nokia.meego, and I fixed the wizard for Qt Creator 2.3 accordingly. I'm sorry for the confusion, I personally learned about the com.nokia.meego namespace just a few days ago.

So... for those of us developing Harmattan apps as we speak: should we move to

@import com.nokia.meego 1.0@

in order to be on the safe side?

Yes, I suggest using "com.nokia.meego 1.0" all over the place.

But "com.nokia.meego 1.0" still gives the error the op and others experience...would be nice to get this issue solved before recommending folks moving to it...

awiese2007, please make sure that you've really no import 'com.meego 1.0' any more in any .qml file used by your application (might also be qml import libraries). If the error is still there, please file a bug report with enough details to reproduce it.

"Change to com.nokia.meego made":https://gitorious.org/miniature/miniature/commit/4b04d58042935286ecca146b98fe830fcec61907 and indeed everything seems to work just like before. Thanks!

I get the following error if I use com.nokia.meego 1.0 as stated in my original post.

file:///usr/lib/qt4/imports/com/meego/PageStack.js:144: Error: Cannot assign QObject* to PageStack_QMLTYPE_24*

That one import line is the only change I do to trigger this. Any ideas why this would happen?

@Kypeli, I guess you use "com.meego 1.0" somewhere in your application, too. If you define the QML_IMPORT_TRACE environment variable before launching the application you should be able to see that.

if i import com.nokia.meego 1.0, i am getting error "Package not found". what shall i do?

WHen do you get the error? When running your app on the device, or in the Simulator? In case it's the latter, check that 'com.nokia.extras platform' is set to 'Harmattan' in the Simulator settings.
