QVirtualKeyboard default style for PySide6 and PySide2 not the same

I use the keyboard in the project written on pyside2, without any additional settings it looks like this:

But the same code on pyside6 displays the keyboard in another style:

How can I use style from pyside2 in pyside6?

Solution

  • One possible solution is to download the qtvirtualkeyboard style from Qt5 and use it in Qt6:

    1. Copy the default style from the Qt5 branch of qtvirtualkeyboard to the qml/QtQuick/VirtualKeyboard/Styles/ folder next to the .py file with another name.

      mkdir -p  qml/QtQuick/VirtualKeyboard/Styles/
git clone -b 5.15.2 https://code.qt.io/qt/qtvirtualkeyboard.git
cp -rf qtvirtualkeyboard/src/virtualkeyboard/content/styles/default qml/QtQuick/VirtualKeyboard/Styles/qt5default

      The structure should be the following:

      ├── main.py
└── qml
    └── QtQuick
        └── VirtualKeyboard
            └── Styles
                └── qt5default
                    ├── images
                    │   ├── backspace-868482.svg
                    │   ├── check-868482.svg
                    │   ├── enter-868482.svg
                    │   ├── globe-868482.svg
                    │   ├── handwriting-868482.svg
                    │   ├── hidekeyboard-868482.svg
                    │   ├── search-868482.svg
                    │   ├── selectionhandle-bottom.svg
                    │   ├── shift-80c342.svg
                    │   ├── shift-868482.svg
                    │   ├── shift-c5d6b6.svg
                    │   └── textmode-868482.svg
                    ├── style.qml
                    └── virtualkeyboard_default_style.qrc

    2. Change line:

      readonly property string resourcePrefix: "qrc:/QtQuick/VirtualKeyboard/content/styles/default/"

      to:

      readonly property string resourcePrefix: ""

    3. In the .py you must include the qml to QML_IMPORT_PATH and set QT_VIRTUALKEYBOARD_STYLE with the new style:

      import os
from pathlib import Path
import sys

from PySide6.QtWidgets import QApplication, QLineEdit

CURRENT_DIRECTORY = Path(__file__).resolve().parent

def main():
    os.environ["QML_IMPORT_PATH"] = os.fspath(CURRENT_DIRECTORY / "qml")
    os.environ["QT_IM_MODULE"] = "qtvirtualkeyboard"
    os.environ["QT_VIRTUALKEYBOARD_STYLE"] = "qt5default"

    app = QApplication(sys.argv)

    w = QLineEdit()
    w.show()

    sys.exit(app.exec())


if __name__ == "__main__":
    main()
