QVirtualKeyboard default style for PySide6 and PySide2 not the same

Question

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?

Answer 1

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()
