Importing components from a plugin

plaristote

Hi !
I made my own plugin using Creating C++ Plugins for QML, and I've been trying to import components in Qt applications using import "qrc:/com/planed/components" or import com.planed.components 1.0, which have led to unsatisfying results:

Importing a directory

Using qrc:/com/planed/components is probably not the proper way to go, and it results in the following error:

Module namespace 'com.planed.components' does not match import URI ':.com.planed.components'

Still, I've been able to import components from sub-folders such as qrc:/com/planed/components/qml, so it is the most functional solution I've had so far...

Importing a module

Using import com.planed.components 1.0 only imports the C++ components registered in the plugin's registerTypes method. The QML components are nowhere to be found, despite the fact that they appear in the qmldir file located at qrc:/com/planed/components/qmldir:

module com.planed.components
linktarget Planedplugin
optional plugin Planedplugin
classname com_planed_componentsPlugin
typeinfo Planed.qmltypes
prefer :/com/planed/components/
View 1.0 View.qml
Window 1.0 Window.qml
Application 1.0 Application.qml
...

I would expect this to work:

import QtQuick 2.15
import com.planed.components 1.0 as Planed

Planed.Window {
  title: "Main window"
}

but while it doesn't complain about com.planed.components not existing, it does claim that Planed.Window is "not a type".

So, how did I end up with an empty module anyway ? How come the components declared in the qmldir file, which are indeed included in the Resource File System at the expected location, are not included with the module ?

I feel you are missing engine.addImportPath("qrc:/") in main.cpp. Can you check this ?

Aaand your feeling was spot on ! That was indeed the issue !
Thank you very much !
