Help with Technical Guide/Keyboard Styles

  • I followed the directions I was successfully able to alter a default style for the keyboard (simple background color change) as shown in the tutorial. So this altered style was placed in QtQuck/VirtualKeyboard/Styles. Would it be possible for me to instead import this Styles directory directly into my Qt Project and reference it from there? That way, if I want my application to run on a different system I wouldn't have to have them create the application with an altered version of the default Qt install directory?

  • I believe this should be possible. I tried creating a "NewFolder" in my project directory. Inside that folder I created a directory tree: QtQuick/VirtualKeyboard/Styles/test as shown:

    rob@linux044:~/QtLocalProjects$ ls
    keyboardTest  something
    rob@linux044:~/QtLocalProjects$ cd keyboardTest/
    rob@linux044:~/QtLocalProjects/keyboardTest$ ls  main.cpp  main.qml  NewFolder  qml.qrc
    rob@linux044:~/QtLocalProjects/keyboardTest$ cd NewFolder/
    rob@linux044:~/QtLocalProjects/keyboardTest/NewFolder$ ls
    rob@linux044:~/QtLocalProjects/keyboardTest/NewFolder$ cd QtQuick/
    rob@linux044:~/QtLocalProjects/keyboardTest/NewFolder/QtQuick$ ls
    rob@linux044:~/QtLocalProjects/keyboardTest/NewFolder/QtQuick$ cd VirtualKeyboard/
    rob@linux044:~/QtLocalProjects/keyboardTest/NewFolder/QtQuick/VirtualKeyboard$ ls
    rob@linux044:~/QtLocalProjects/keyboardTest/NewFolder/QtQuick/VirtualKeyboard$ cd Styles
    rob@linux044:~/QtLocalProjects/keyboardTest/NewFolder/QtQuick/VirtualKeyboard/Styles$ ls
    rob@linux044:~/QtLocalProjects/keyboardTest/NewFolder/QtQuick/VirtualKeyboard/Styles$ cd test
    rob@linux044:~/QtLocalProjects/keyboardTest/NewFolder/QtQuick/VirtualKeyboard/Styles/test$ ls
    images  style.qml  virtualkeyboard_default_style.qrc

    then in main I tried setting the import path:

    #include <QGuiApplication>
    #include <QQmlApplicationEngine>
    int main(int argc, char *argv[])
        qputenv("QT_IM_MODULE", QByteArray("qtvirtualkeyboard"));
        //qputenv("QML2_IMPORT_PATH", ":/NewFolder/QtQuick/VirtualKeyboard/Styles/test");
        QGuiApplication app(argc, argv);
        QQmlApplicationEngine engine;
        qputenv("QT_VIRTUALKEYBOARD_STYLE", "test");
        const QUrl url(QStringLiteral("qrc:/main.qml"));
        QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
                         &app, [url](QObject *obj, const QUrl &objUrl) {
            if (!obj && url == objUrl)
        }, Qt::QueuedConnection);
        return app.exec();

    what am I doing wrong here? Perhaps I imported the existing directory incorrectly? I just right-clicked the project name and clicked import existing directory.

  • Okay I see what I did wrong @test/virtualkeyboard_default_style.qrc the qresource prefix was set too: "/QtQuick/VirtualKeyboard/content/styles/default" instead it needed to be set too: "/QtQuick/VirtualKeyboard/content/styles/test" now it is working :)
