Loading a qmldir from a qrc file

bunjee

Greetings,

I'm trying to load a QML module from the qrc file.

Here is how my qrc file looks:
@<RCC>
<qresource prefix="/">
<file>content/Main.qml</file>
<file>content/SkyComponents/PushButton.qml</file>
<file>content/SkyComponents/qmldir</file>
</qresource>
</RCC>@
Here is how my Main.qml looks:
@import SkyComponents 1.0

...@
I also added this in my cpp files:
@wControllerDeclarative->engine()->addImportPath("qrc:/");@

I get the following error:

Couldn't create Main QML Object: qrc:/content/Main.qml:3 module "SkyComponents" is not installed

Is it possible to load qmldir(s) from the qrc file ?

Thanks.

can you try
@
import content.SkyComponents 1.0
@
Not sure if it works, but you can give it a try.

Hi there,

I tried it with no luck.

Indeed I want to keep the very same QML files when I'm using qrc or the filesystem.

Modifying the qml files for any scenario is kind of my last option.

What does "import tracing":http://www.developer.nokia.com/Community/Wiki/How_to_enable_QML_Import_Traces#QML_IMPORT_TRACE_with_Qt say?

Good call. I did not know this command...

@QDeclarativeImportDatabase::addImportPath: "qrc:/"
QDeclarativeImports(qrc:/content/Main.qml)::addImport: "." -1.-1 File as ""
QDeclarativeImports(qrc:/content/Main.qml)::addImport: "QtQuick" 1.0 Library as ""
QDeclarativeImports(qrc:/content/Main.qml)::addImport: "Sky" 1.0 Library as ""
QDeclarativeImports(qrc:/content/Main.qml)::addImport: "SkyComponents" 1.0 Library as ""
QDeclarativeComponent: Component is not ready
Couldn't create Main QML Object: qrc:/content/Main.qml:3 module "SkyComponents" is not installed@

Looks like it could be a Qt bug.

Shall I do a bug report ?

Thanks to vallidor from www.qtcentre.org we have a working model for this:

I didn't test it, but sample provided is part of a working solution.

My solution is like this :
<1>
@
<RCC>
<qresource prefix="/">
<file alias="MyComp.qml">myComponentPath/MyComp.qml</file>
</qresource>
</RCC>
@

And in my main.qml

@
import "qrc:/."

MyComp {
......
}
@

<2>
And I also try to put the path only on qrc's file tag's value :

@
<RCC>
<qresource prefix="/">
<file alias="MyCom">myComponentPathFolder</file>
</qresource>
</RCC>
@

In my main.qml
@
import "qrc:/MyCom"
MyComp {
......
}
@

It also works!! But there is a bug by this method, thing like when I put many components in that path, it will appear wrong component's declarative as if I put many components on main.qml.

No matter what, the first tricks can help you ~

Can't seem to load a module on Qt 4.8.3 for now.

So:

I flattened my module directory.
Copy / pasted all the qml files in the same folder.
Exported that folder into a qrc file.

It works just fine.
