PyQt or PySide - which one to use [closed]

由 霸气de小男生 提交于 2019-12-02 14:48:36
I started learning a bit of python and would now like to toy around a bit with gui-building. Qt seems to be a good choice because of its cross-platformishness. Now there seem to be two bindings available: PyQt by Riverbank Computing and PySide, originally developed by Nokia. So which one should I choose? All I can find are two year old feature comparisons, but what differences are there nowadays? Which one is easier to use, has more/better documentation? Are both still in active development? Licensing isn't of much concern to me since I don't intend to write commercial applications. Both

PYQT: How to capture output of python's interpreter and display it in QEditText?

问题 With reference to the post here. Can someone give me a detailed explanation on how to append the print statement's output to the QEditext in PYQT... I tried the code given above but it was incomplete and I got: TypeError: connect() slot argument should be a callable or a signal, not 'QTextEdit' In the first file i wrote: from PyQt4 import QtCore class EmittingStream(QtCore.QObject): textWritten = QtCore.pyqtSignal(str) def write(self, text): self.textWritten.emit(str(text)) In a seperate file

QComboBox with autocompletion works in PyQt4 but not in PySide

由 自作多情 提交于 2019-12-02 12:29:02
问题 I've got a combo box with a custom completer that worked fine in PyQt4, but isn't working in PySide. I have verified that the new completer is replacing the QComboBox's built in completer because inline completion is no longer occurring. However when run with PySide, the completer doesn't popup with a filtered list of options. I've also tried ensuring that all text is all str or all unicode to avoid differences between the PyQt API 1 with QStrings and PySide's use of Python unicode types.

How can I send a list object from a QThread thread to the UI's main thread?

问题 I have written this example code to try and figure out how to communicate between a background thread, and the main thread. As I understand it, a thread cannot simply interact with the UI or variables existing in a different thread. I would like to grab the list 'data' in the background thread, then display it on 'lbl2' in the UI. If this program is run as is, it will print the result I want on the command line. Data received in background thread = [1, 2, 3, 4, 5] Q1: What is the correct way

How to get value from QDialog using multiple class

问题 I am currently working in a panel in Nuke 11 that opens a QDialog and I was wondering how to get a value from it into my main class when I close my QDialog ? The QDialog is in a different class. This is a simplified example that shows my problem : import nuke from nukescripts import panels try: ## < Nuke11 import PySide.QtGui as QtGui import PySide.QtCore as QtCore except: ## >= Nuke11 import PySide2.QtCore as QtCore import PySide2.QtGui as QtGui import PySide2.QtWidgets as QtGui from PySide2

Duplicate stdout, stderr in QTextEdit widget

问题 I've been having difficulty with my PySide program for a few days now. I don't think the problem is incredibly difficult because there are answer out there. Problem I have is none of them seem to work for me. I want to 'listen' to the file objects stdout and stderr and output the contents to QText Edit widget while my PySide program is running. Now, I already realise this question (or something similar) has been asked before on here but like I said, can't get it to work for me for some reason
