問題描述
我正在使用 pyqt5 開發桌面應用程序，我想使用帶有手寫識別功能的虛擬鍵盤.我看到Qt，QtVirtualKeyboard已經支持了.
這里是
我得到了在 QtCreator 上運行的 C++ Qt 示例代碼.但是使用 python3.5 和 PyQt5 會給出這樣的信息:
模塊QtQuick.VirtualKeyboard"未安裝導入 QtQuick.VirtualKeyboard 2.1我應該如何從這里繼續?PyQt5 是否帶有 VirtualKeyboard 模塊?如果沒有，如何在 PyQt5 上安裝?
對于 qt desinger，您只能在 .py 文件中添加這一行.
os.environ["QT_IM_MODULE"] = "qtvirtualkeyboard"但是如果你想使用 QML 和 qtvirtualkeyboard;
pyqt5.8沒有虛擬鍵盤插件，必須使用qt的路徑.
例如，在 ubuntu 上安裝 pyqt5、qt5.8 和 qtvirtualkeyboard 的基本步驟:
1.step 用qtvirtualkeyboard安裝qt5.8
<塊引用>wgethttp://下載.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
<塊引用>apt-get 安裝 python3 python3-pippip3 安裝 pyqt5
3.step
在你的python代碼上設置你的qt路徑的環境變量.

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?
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"
