Does PyQt5/pyqt4 already supports QtVirtualKeyboard with Handwriting Recognition?

Question

I\'m working on a desktop application using pyqt5, and I want to use a Virtual Keyboard with Handwriting Recognition. I saw that Qt, QtVirtualKeyboard already support it.

Answer 1

for qt desinger you can add only this line on your .py file.

os.environ["QT_IM_MODULE"] = "qtvirtualkeyboard"

but If you want use QML with qtvirtualkeyboard;

There is no virtualkeyboard plugin in pyqt5.8, you must be use qt's paths.

For a example, basic steps for pyqt5, qt5.8 and qtvirtualkeyboard installiation on ubuntu:

1.step install qt5.8 with qtvirtualkeyboard

wget http://download.qt.io/official_releases/qt/5.8/5.8.0/qt-opensource-linux-x64-5.8.0.run

chmod +x qt-opensource-linux-x64-5.8.0.run

./qt-opensource-linux-x64-5.8.0.run

2.step

apt-get install python3 python3-pip pip3 install pyqt5

3.step

set environmental variables your qt paths on your python code.

import sys, os
os.environ["QT_DIR"] = "/opt/Qt5.8.0/5.8/gcc_64"
os.environ["QT_QPA_PLATFORM_PLUGIN_PATH"] = "/opt/Qt5.8.0/5.8/gcc_64/plugins/platforms"
os.environ["QT_PLUGIN_PATH"] = "/opt/Qt5.8.0/5.8/gcc_64/plugins"
os.environ["QML_IMPORT_PATH"] = "/opt/Qt5.8.0/5.8/gcc_64/qml"
os.environ["QML2_IMPORT_PATH"] = "/opt/Qt5.8.0/5.8/gcc_64/qml"
os.environ["QT_IM_MODULE"] = "qtvirtualkeyboard"

#print(os.environ) 

from PyQt5.QtCore import *
from PyQt5 import QtCore
from PyQt5.QtWidgets import *
from PyQt5.QtQuick import *


class keyboardapp(object):
    def __init__(self):
        self.view = QQuickView()
        self.view.setObjectName("View")
        #self.view.setFlags(Qt.FramelessWindowHint)
        self.view.setSource(QUrl("main.qml"))
        self.view.setResizeMode(QQuickView.SizeRootObjectToView)
        #self.Screen = self.view.rootObject()
        #print("Screen(Root) = " + str(self.Screen))
        self.view.show()

app = QApplication(sys.argv)
test = keyboardapp()
sys.exit(app.exec_())
