PyQt5/pyqt4 是否已经支持带有手写识别的 QtVirtualKeyboard?

问题描述

我正在使用 pyqt5 开发桌面应用程序，我想使用带有手写识别功能的虚拟键盘.我看到Qt，QtVirtualKeyboard已经支持了.

这里是

我得到了在 QtCreator 上运行的 C++ Qt 示例代码.但是使用 python3.5 和 PyQt5 会给出这样的信息:

模块QtQuick.VirtualKeyboard"未安装导入 QtQuick.VirtualKeyboard 2.1

我应该如何从这里继续?PyQt5 是否带有 VirtualKeyboard 模块?如果没有，如何在 PyQt5 上安装?

解决方案

对于 qt desinger，您只能在 .py 文件中添加这一行.

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

但是如果你想使用 QML 和 qtvirtualkeyboard;

pyqt5.8没有虚拟键盘插件，必须使用qt的路径.

例如，在 ubuntu 上安装 pyqt5、qt5.8 和 qtvirtualkeyboard 的基本步骤:

1.step 用qtvirtualkeyboard安装qt5.8

wgethttp://下载.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 安装 python3 python3-pippip3 安装 pyqt5

3.step

在你的python代码上设置你的qt路径的环境变量.

导入系统，操作系统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)从 PyQt5.QtCore 导入 *从 PyQt5 导入 QtCore从 PyQt5.QtWidgets 导入 *从 PyQt5.QtQuick 导入 *类键盘应用程序(对象):def __init__(self):self.view = QQuickView()self.view.setObjectName("视图")#self.view.setFlags(Qt.FramelessWindowHint)self.view.setSource(QUrl("main.qml"))self.view.setResizeMode(QQuickView.SizeRootObjectToView)#self.Screen = self.view.rootObject()#print("屏幕(根) = " + str(self.Screen))self.view.show()应用程序 = QApplication(sys.argv)测试 = 键盘应用程序()sys.exit(app.exec_())

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.

Here's a link!

I got the C++ Qt example code running on QtCreator.But using python3.5 and PyQt5 it gives this message:

module "QtQuick.VirtualKeyboard" is not installed
 import QtQuick.VirtualKeyboard 2.1

How should I go on from here?Does PyQt5 comes with VirtualKeyboard module? if no How to install it on PyQt5?

解决方案

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

2.step

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_())
