在 PyQt5 中嵌入终端-Python问题

Embedding a terminal in PyQt5(在 PyQt5 中嵌入终端)

本文介绍了在 PyQt5 中嵌入终端的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

所以我一直在尝试创建自己的终端，但事实证明这非常有问题，而且看起来不专业.

So I've been trying to create my own terminal but that has been proven very glitchy and not professional looking.

然后我偶然发现了这段用于 PyQt4 的代码:

Then I stumbled across this code which is for PyQt4:

#!/usr/bin/env python
#-*- coding:utf-8 -*-

import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *


class embterminal(QWidget):

    def __init__(self):
        QWidget.__init__(self)
        self.process = QProcess(self)
        self.terminal = QWidget(self)
        layout = QVBoxLayout(self)
        layout.addWidget(self.terminal)
        #self.process.start(
                #'xterm',['-into', str(self.terminal.winId())])
        # Works also with urxvt:
        self.process.start(
                'urxvt',['-embed', str(self.terminal.winId())])


if __name__ == "__main__":
    app = QApplication(sys.argv)
    main = embterminal()
    main.show()
    sys.exit(app.exec_())

由于我的应用程序是用 PyQt5 编写的，我自然而然地尝试将该代码移植到 PyQt5.我从 PyQt4.QtCore import * 更改了 从 PyQt4.QtGui 导入 * 到 从 PyQt5.QtCore 导入 *from PyQt5.QtGui import * 并添加 from PyQt5.QtWidgets import *

Since my application is written in PyQt5, I naturally tried porting that code to PyQt5. I changed from PyQt4.QtCore import * from PyQt4.QtGui import * to from PyQt5.QtCore import * from PyQt5.QtGui import * and added from PyQt5.QtWidgets import *

然后当我运行我的代码时，我意识到终端没有弹出.

Then when I ran my code I realized the terminal didn't pop up.

我想知道为什么会发生这种情况，是否有解决方法?

I wonder why does this happen and is there a workaround ?

我也想知道我是否可以在同一个项目/文件中同时使用 PyQt5 和 PyQt4.

I also wonder if I can use both PyQt5 and PyQt4 in the same project/file, even.

推荐答案

在 PyQt.QWidget.winId() 返回一个 sip.voidptr 对象，但如果将其转换为整数，它应该可以工作.这是一个工作示例:

In PyQt. QWidget.winId() returns a sip.voidptr object, but if you convert it to an integer, it should work. Here's a working example:

import sys
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *

class Window(QWidget):
    def __init__(self):
        super().__init__()
        self.process = QProcess(self)
        self.terminal = QWidget(self)
        layout = QVBoxLayout(self)
        layout.addWidget(self.terminal)
        wid = str(int(self.terminal.winId()))
        self.process.start('urxvt', ['-embed', wid])

    def closeEvent(self, event):
        self.process.terminate()
        self.process.waitForFinished(1000)

if __name__ == "__main__":

    app = QApplication(sys.argv)
    window = Window()
    window.setGeometry(100, 100, 800, 600)
    window.show()
    sys.exit(app.exec_())
