如何在没有 QProcess 的情况下将终端嵌入 PyQt5 应用程序中?

问题描述

我最近一直在努力在 PyQt GUI 应用程序中嵌入终端.几乎尝试了互联网上的所有搜索，但没有任何帮助.

I have been struggling lately with embedding a terminal inside PyQt GUI app. Tried almost every search on Internet but nothing looks like of any help.

我有一个 QTabWidget，我只需要一个标签就有一个终端.

I have a QTabWidget and I simply need one tab to have a terminal.

根本不可能这样做吗?

难道没有像 QTabWidget.Tab2.show(terminal-app) 这样的东西吗?默认终端会显示在 tab2 中，每个函数都像 ls、ifconfig、cd 等工作正常吗?

Isn't there something like QTabWidget.Tab2.show(terminal-app) and default terminal gets displayed in tab2 and every function like ls, ifconfig, cd etc works fine ?

P.S - 我已经尝试过这些但没有成功.在 PyQt5 中嵌入终端

解决方案

简答: Qt5不提供终端的使用，所以你必须使用QProcess.

short answer: Qt5 does not provide the use of the terminal, so you will have to use QProcess.

TL;DR

作为解决方案提出的 EmbTerminal 类是一个小部件，因此您必须使用 addTab() 添加它，请记住您必须已安装 urxvt 终端(如果你想检查你的安装在终端运行 urxvt)

The EmbTerminal class that is proposed as a solution is a widget so you must add it with addTab(), keep in mind that you must have installed the urxvt terminal (if you want to check your installation run urxvt in the terminal)

import sys
from PyQt5 import QtCore, QtWidgets


class EmbTerminal(QtWidgets.QWidget):
    def __init__(self, parent=None):
        super(EmbTerminal, self).__init__(parent)
        self.process = QtCore.QProcess(self)
        self.terminal = QtWidgets.QWidget(self)
        layout = QtWidgets.QVBoxLayout(self)
        layout.addWidget(self.terminal)
        # Works also with urxvt:
        self.process.start('urxvt',['-embed', str(int(self.winId()))])
        self.setFixedSize(640, 480)


class mainWindow(QtWidgets.QMainWindow):
    def __init__(self, parent=None):
        super(mainWindow, self).__init__(parent)

        central_widget = QtWidgets.QWidget()
        lay = QtWidgets.QVBoxLayout(central_widget)
        self.setCentralWidget(central_widget)

        tab_widget = QtWidgets.QTabWidget()
        lay.addWidget(tab_widget)

        tab_widget.addTab(EmbTerminal(), "EmbTerminal")
        tab_widget.addTab(QtWidgets.QTextEdit(), "QTextEdit")
        tab_widget.addTab(QtWidgets.QMdiArea(), "QMdiArea")


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