[SOLVED] QML Extension plugin

a.v.mich

Hello, today i have installed qt 4.7.0 for mingw and tried to launch example "chapter6-plugins" from "Tutorial: Writing QML extensions with C++" and i've got nothing.

@Application output - Starting e:\progr\Qt\4.7.0\bin\qmlviewer.exe -I e:/progr/Qt/4.7.0/imports E:/progr/Qt/4.7.0/examples/declarative/tutorials/extending/chapter6-plugins/app.qml
file:///E:/progr/Qt/4.7.0/examples/declarative/tutorials/extending/chapter6-plugins/app.qml:45:5: PieChart is not a type
PieChart {
^

I have not modified an example. The same situation under Qt 4.7.1 for mingw. What am i doing wrong?

Do you have PieChart.qml file included on your project?

Kxyu

Have you compiled the plugin?

a.v.mich

Milot, PieChart is QDeclarativeExtensionPlugin. Yo can go to $QTDIR/examples/declarative/tutorials/extending/chapter6-plugins and look on this example.

Kxyu, I have installed qt-win-opensource-4.7.0-mingw.exe where all examples are already compiled.

Strange enough. I just tried compiling the example on Mac and it works!

Also I was able to open the QML file with QMLViewer, can you try the same?

Can you post the compiler error? The above error is QMLViewer error...

i do not compile this example, it was already compiled when i've installed qt.

qmlviewer gave me follow output "file:///E:/progr/Qt/4.7.0/examples/declarative/tutorials/extending/chapter6-plugins/app.qml:45:5: PieChart is not a type
PieChart {

With turning on QML_IMPORT_TRACE i recieve this

@QDeclarativeImportDatabase::addToImport 0x10db4fec "." -1.-1 File as ""
QDeclarativeImportDatabase::add: loaded "E:/progr/Qt/4.7.0/examples/declarative/tutorials/extending/chapter6-plugins/qmldir"

Strange enough!

Do you have contents (any lib, dll or something) under lib directory?

Here I have .dylib library for Mac OS.

a.v.mich

yes - both - chapter6-plugins.dll and libchapter6-plugins.a

milot.shala

Strange again.

Maybe someone who faced the issue can help us here, I will try that on the meantime on Windows.

That can work, and this is a bit an issue with not working examples, most of the developers are facing this issue which is also specified in "this article.":http://www.pluggd.in/nokia-qt-297/

a.v.mich

finally an example from the latest version of the library started. Thanks to all!

Good to hear that! Can you mark this thread as [SOLVED] ?
