qprocess

问题 I am developing a Qt application that, among other things, converts an Excel spreadsheet in a text delimited with tab file. This is done by running a Windows Powershell script. My problem is that the finished() signal from the QProcess is never emitted, although the conversion is done successfully. And yes, I receive stateChanged() signal. Powershell script (ps_excel.ps1) (adapted from this question) param ([string]$ent = $null, [string]$sal = $null) $xlCSV = -4158 #value for tab delimited

问题 I want to run a python script in my qt project after clicking a pushButton using QProcess. This is my code : void MainWindow::on_pushButton_clicked() { QProcess p; QStringList params; QString pythonPath = "C:/Python/python.exe"; QString pythonScript = "C:\\Users\\melek\\Desktop\\user_interface\\user_interface-master\\match.py"; params << pythonScript; QStringList arguments; arguments <<"-t1"<<"start.png"<<"-t2"<< "end.png"<<"-i"<< "images_"; p.setArguments(arguments); p.start(pythonPath,

问题 A PyQt4 app runs ping in a QProcess . A QTextEdit named self.output will output everything from ping . A second QTextEdit named self.summary will only output the line if it contains the string TTL . Problem: I have managed to get self.output working but not self.summary as I am not sure how to write its code in the dataReady function. Any ideas? import sys from PyQt4 import QtGui, QtCore class MainWindow(QtGui.QMainWindow): def __init__(self): super(MainWindow, self).__init__() self.initUI()

问题 I'm attempting to write some software that will process large amounts of images collected from some crystallography experiments. The data process involves the following steps: User Input to determine the number of images to batch together. A directory containing the images is selected, and the total number of images is calculated. A nested for loop is used to batch images together, and construct a command and arguments for each batch which is processed using a batch file. The following code

问题 I have a PyQt window that calls multiple executables as QProcess. How can I list the outputs of each process after the last one has finished? (something like process_result = ["result1", "result2",..]) Let us say it looks like this: for i in list_of_processes: process = QtCore.QProcess() process.start(i) I can read with process.readyReadStandardOutput() somehow but it is quite chaotic because processes run parallel. process.waitForFinished() does not work because the GUI will freeze. Also, I

问题 I've been struggling with this for quite a while. I've managed to write a code that can capture STDOUT of .py files, however when I run the exact same code with executable generated from Pyinstaller (doesn't matter whether it's windowed or not) the readyReadStandardOutput signal doesn't ever come up. From my tests it occurs that any signal at all is emitted only when the app crashes, however I need a live communication between the GUI and the executable. Here's my code for reference: def
