QML file from extension plugin -> "Unknown component"

Bilouse

Hi all,

I still manage to build properly a custom QML lib, so I built an extension plugin.

Everything works fine except...code completion within QtCreator. But it works during execution.

My custom QML type (defined in a QML file, not a QML binding from C++) isn't recognized by the QML editor. It's very frustrating.

I tried many things...it never works.

Here's my project's structure :

src
-- app
---- some things
---- qml.qrc
------ main.qml // error M300
-- libs
---- customquick // Folder of QML plugins
------ controls // my extension plugin
-------- customquickcontrolsplugin.(h/cpp)
-------- gridmenulogic.(h/cpp) // C++ binding class
-------- GridMenu.qml // the type which isn't recognized in main.qml
-------- qmldir

My qmldir :
@module customquick.controls
GridMenu 1.0 GridMenu.qml
plugin customquickcontrolsplugin
classname CustomQuickControlsPlugin
@

main.qml
@import QtQuick 2.2
import QtQuick.Window 2.1
import customquick.controls 1.0

Window {
visible: true
width: 360
height: 360

GridMenu { *// <-- M300 error*
    id: menu
    anchors.fill: parent
}

}@

GridMenu.qml
@import QtQuick 2.0
import customquick.controls 1.0

Item {
width: 100
height: 80

GridMenuLogic {

}

}
@

And my CustomQuickControlsPlugin class :
@void CustomQuickControlsPlugin::registerTypes(const char *uri)
{
// @uri controls
Q_ASSERT(uri == QLatin1String("customquick.controls"));
qmlRegisterType<GridMenuLogic>(uri, 1, 0, "GridMenuLogic");
}
@

The project copies the .qml files to the build directory and I setted the "QML2_IMPORT_PATH" environment var. But GridMenu is still underlined in main.qml...

I works with QtCreator 3.2.0 and Ubuntu 14.04.

Thanks for your help.

Hi,

Did you try put this line in main.qml?
#import GridMenuLogic 1.0

Thanks for your reply.

Yes, it doesn't work, the engine deosn't recognize it as a module.

I tried to put GridMenu.qml in main.qml folder, and import with

"import GridMenu.qml"

but it failed too.

Well,

Try to put GridMenu folder's path in a "import" clause, like this:

main.qml:
#import "../libs/customquick/controls".

Well well well... It works...partially :p

Firstly, I got a...warning (in french) :
"The QML module contains some C++ modules, reading type informations...".

So, GridMenu is recognized by the code model, but if I run the program it doesn't work anymore :

"QQmlApplicationEngine failed to load component
qrc:///main.qml:5 "../libs/customquick/controls": no such directory"

Maybe because main.qml is within a Qt resource file ?

EDIT : ok...it's because the qrc file. If I copy main.qml in the build directory and I delete it from the resource file, It works. The "import" is still yellow underlined.
