Plugin type not recognized

[RadiumBall]

Hi,
I am trying to build a simple plugin with multiple components Button, Checkbox etc. But When I try to use this plugin library in an application I get error "Widget is not a Type". Also please help with importing the plugin correctly.

Thank you,
Ashwin

@RadiumBall Please show the code where you load and use the plug-in.
"Widget is not a Type" - this means that Widget is not known to the compiler - did you forget to include the header file where Widget is declared?

@jsulm Thank you very much.
Here is my button widget

import QtQuick 2.12
import QtQuick.Controls 2.12

Button {
    id: button

    /** sets Button Text visible*/
    property bool   bIsButtonTextVisible: true

    ....

Here is my CheckBox Widget

import QtQuick 2.0
import QtQuick.Controls 2.12


Rectangle{
    id :checkBox

    /** checkbox current state checked / unchecked */
    property bool checked: true

    ...

Here is my cpp code

#include "widgets_plugin.h"


#include <qqml.h>

void WidgetsPlugin::registerTypes(const char *uri)
{
    // @uri com.mycompany.qmlcomponents
    qmlRegisterType(QUrl("qrc:/EDSButton/Source/component/ButtonWidget.qml"), uri, 1, 0, "ButtonWidget");
    qmlRegisterType(QUrl("qrc:/EDSCheckBox/Source/component/CheckBoxWidget.qml"), uri, 1, 0, "CheckBoxWidget");
}

Here is my header file

#ifndef WIDGETS_PLUGIN_H
#define WIDGETS_PLUGIN_H

#include <QQmlExtensionPlugin>

class WidgetsPlugin : public QQmlExtensionPlugin
{
    Q_OBJECT
    Q_PLUGIN_METADATA(IID QQmlExtensionInterface_iid)

public:
    void registerTypes(const char *uri) override;
};

#endif // WIDGETS_PLUGIN_H

All this packaged into a library.

Here is my application cpp

#include <QGuiApplication>
#include <QQmlApplicationEngine>

int main(int argc, char *argv[])
{
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);

    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    const QUrl url(QStringLiteral("qrc:/main.qml"));
    QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
                     &app, [url](QObject *obj, const QUrl &objUrl) {
        if (!obj && url == objUrl)
            QCoreApplication::exit(-1);
    }, Qt::QueuedConnection);
    engine.load(url);

    return app.exec();
}

And here is my main qml

import QtQuick 2.9
import QtQuick.Window 2.2
//import "qrc:/EDSCheckBox/Source/component"
import "C:\Users\RadiumBall\Downloads\EDSCheckBoxComponent\EDS_Component\debug\Widgets.dll"

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    CheckBoxWidget{
        id : testCheckBox
        rCheckboxConfigureHeight: 24
        rCheckboxConfigureWidth: 24
        rCheckboxConfigureRadius: 1
        rCheckboxConfigureImgHeight: 16
        rCheckboxConfigureImgWidth: 16
        sCheckBoxLabel: "CheckBox"


    }

I am doing two mistakes here, one is w.r.t importing the library and other complier throws me error 'CheckBoxWidget' is not a type.

PS: The CheckBoxWidget qml works perfectly fine when included directly but fails when included as a library.

Please help.
