Minimal working example for qtvirtualkeyboard - keyboard not showing up

DrEmbo

Hello there,

I am trying to get a small test program for qt virtual keyboard running. I have created a QtQuick application and added the following code to the main.qml

import QtQuick 2.15
import QtQuick.Window 2.15
import QtQuick.VirtualKeyboard 2.15

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

    TextInput {
        text: "Text"
        cursorVisible: false
        activeFocusOnPress:true
    }
}

main.cpp looks like this:

#include <QGuiApplication>
#include <QQmlApplicationEngine>


int main(int argc, char *argv[])
{
    qputenv("QT_IM_MODULE", QByteArray("qtvirtualkeyboard"));

#if QT_VERSION < QT_VERSION_CHECK(6, 0, 0)
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
#endif
    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();
}

When I run it on my Ubuntu the virtual keyboard shows up and I can use it accordingly.
However, if I cross-compile it for the embedded platform and start it I can see the text, but when I
click on it I can see the cursor but the keyboard is not showing.

I am using the eglfs platform.
The strace command shows that the virtual keyboard plugin is being loaded.

Maybe I am missing something very important, therefore I would appreciate your help.

Best regards,
Drembo
