我有这个简单的代码:基本上是一个向 cmd 发送一些命令并在 QTextEdit 中显示 cmd 输出的工具。基本上,它有效。我遇到的唯一问题是每次单击发送(有或没有新命令)时,都会附加文本,但 QTextEdit 的末尾会出现奇怪的空白行。即使我清除“控制台”,仍然有这些行。也许这与我调用该过程的方式有关,我不知道因此需要帮助。

from PySide.QtCore import *
from PySide.QtGui import *
import sys


class MyWindow(QDialog):
    def __init__(self, parent=None):
        super(MyWindow, self).__init__(parent)

        self.setWindowTitle("Send to CMD")

        self.check1 = QCheckBox("Activate Variable")
        self.variable = QLineEdit()
        self.finalcommand = QLineEdit()
        self.clearCommand = QPushButton("Clear")
        self.sendCommand = QPushButton("Send")
        self.clearOnSend = QCheckBox("Clear on Send")

        self.process = QProcess()
        self.console = QTextEdit(self)

        layout = QVBoxLayout()
        layout.addWidget(self.check1)
        layout.addWidget(self.variable)
        layout.addWidget(self.finalcommand)
        layout.addWidget(self.clearOnSend)
        layout.addWidget(self.clearCommand)
        layout.addWidget(self.sendCommand)
        layout.addWidget(self.console)
        self.setLayout(layout)

        self.connect(self.check1, SIGNAL("clicked()"), self.appendText)
        self.variable.textChanged.connect(self.appendText)

        self.clearCommand.clicked.connect(self.Clear)
        self.sendCommand.clicked.connect(self.Send)

    def appendText(self):
        if self.check1.isChecked():
            TEXT1 = "Dir" + ' ' + str(self.variable.text())
        else:
            TEXT1 = ""
        self.finalcommand.setText(str(TEXT1))

    def Clear(self):
        if self.clearCommand.isEnabled():
            self.console.clear()

    def Send(self):
        if self.clearOnSend.isChecked():
            self.console.clear()
        FCTS = "cmd.exe /c" + " " + str(self.finalcommand.text())
        self.process.readyReadStandardOutput.connect(self.readConsole)
        self.process.start(FCTS)
        if not self.process.waitForStarted(0):
            return False
        if not self.process.waitForFinished(0):
            return False

    def readConsole(self):
        #self.console.setText(str(self.process.readAllStandardOutput()))
        self.console.append(str(self.process.readAllStandardOutput()))



app = QApplication(sys.argv)
form = MyWindow()
form.show()
app.exec_()

如果你改变

self.console.append(str(self.process.readAllStandardOutput()))

self.console.append(str([self.process.readAllStandardOutput()]))

你可以看到发生了什么,希望这会有所帮助

您可能想使用 string.rstrip() 函数而不是 string.strip()
