将每个进程的 output 重定向到 QtabWidget 选项卡

Question

任何人都可以帮助修复此脚本我想将每个进程 output 分成 tab1 和 tab2。

tab1 output 就像在此处输入图像描述

tab2 output 就像在此处输入图像描述

有什么方法可以分离进程 output

有许多不同的方法可以实现你想要的。
此解决方案使用 header 作为数据标识符。
然后您可以根据其 header 根据需要解释您的数据。

这是您修改后的代码：

import datetime
import sys
import time
from multiprocessing import Process, Queue

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


def producer(q, header):
    while True:
        data = str(datetime.datetime.now())
        q.put((header, data))
        time.sleep(1)


def counting(q, header):
    count = 1
    while True:
        data = str(count)
        q.put((header, data))
        time.sleep(1)
        count += 1


class Consumer(QThread):
    poped = pyqtSignal(int, str)

    def __init__(self, q):
        super().__init__()
        self.q = q

    def run(self):
        while True:
            if not self.q.empty():
                self.poped.emit(*q.get())


class MyWindow(QMainWindow):
    def __init__(self, q):
        super().__init__()
        self.setGeometry(200, 200, 300, 200)
        self.layout = QVBoxLayout(self)

        # Initialize tab screen
        self.tabs = QTabWidget()
        self.tab1 = QWidget()
        self.tab2 = QWidget()
        self.tab3 = QWidget()
        self.tabs.resize(300, 200)

        # Add tabs
        self.tabs.addTab(self.tab1, "Tab1")
        self.tabs.addTab(self.tab2, "Tab2")
        self.tabs.addTab(self.tab3, "Tab3")

        # Create first tab
        self.tab1.layout = QVBoxLayout(self)
        self.tab2.layout = QVBoxLayout(self)
        self.text = QPlainTextEdit()
        self.text.setReadOnly(True)
        self.text2 = QPlainTextEdit()
        self.text.setReadOnly(True)
        self.tab1.layout.addWidget(self.text)
        self.tab1.setLayout(self.tab1.layout)
        self.tab2.layout.addWidget(self.text2)
        self.tab2.setLayout(self.tab2.layout)

        # Add tabs to widget
        self.layout.addWidget(self.tabs)
        self.setLayout(self.layout)

        self.setCentralWidget(self.tabs)

        # thread for data consumer
        self.consumer = Consumer(q)
        self.consumer.poped.connect(self.print_data)
        self.consumer.start()

    @pyqtSlot(int, str)
    def print_data(self, header, data):
        self.statusBar().showMessage(data)
        if header == 0:
            self.text.appendPlainText(data)
        elif header == 1:
            self.text2.appendPlainText(data)
