问题 I'm trying to create a filter for QTableWidget with QLineEdit in PySide. I've seen some tutorials using QSortFilterProxyModel for C++ but couldn't understood how to do it in Python. I need to search in 'VALUE' column. 回答1: A QSortFilterProxyModel is a proxy model, that means that you put it between the your complete data model and a view. The comment by titusjan is good, you can look in your local PySide/PyQt installation for basicsortfiltermodel.py to get an example in Python. Also, instead

问题 I'm trying to do a fairly common thing in my PySide GUI application: I want to delegate some CPU-Intensive task to a background thread so that my GUI stays responsive and could even display a progress indicator as the computation goes. Here is what I'm doing (I'm using PySide 1.1.1 on Python 2.7, Linux x86_64): import sys import time from PySide.QtGui import QMainWindow, QPushButton, QApplication, QWidget from PySide.QtCore import QThread, QObject, Signal, Slot class Worker(QObject): done

问题 Short version How do you implement undo functionality for edits made on QListWidgetItems in PySide/PyQt? Hint from a Qt tutorial? The following tutorial written for Qt users (c++) likely has the answer, but I am not a c++ person, so get a bit lost: Using Undo/Redo with Item Views Longer version I am using a QListWidget to learn my way around PyQt's Undo Framework (with the help of an article on the topic). I am fine with undo/redo when I implement a command myself (like deleting an item from

问题 When I try to install PySide for Python-3.6, it says it is only compatible until Python-3.4. Is there any work-around to get it installed for Python-3.6? Only these Python versions seem to be supported: [(2, 6), (2, 7), (3, 2), (3, 3), (3, 4)]. 回答1: Firstly, it should be pointed out that PySide depends on Qt4, which is no longer officially supported (as of December 2015). In consequence, all development efforts are now focused on PySide2 and Qt5. According to this tracker issue, there are no

问题 I need help inserting a button inside in a QLineEdit that can call a function. For example, like this google image: 回答1: Below is a nearly direct translation of the Qt code from here. Differences: button is always visible clicking on the button emits buttonClicked(bool) signal Code: from PyQt4 import QtGui, QtCore class ButtonLineEdit(QtGui.QLineEdit): buttonClicked = QtCore.pyqtSignal(bool) def __init__(self, icon_file, parent=None): super(ButtonLineEdit, self).__init__(parent) self.button =

问题 I'm building a PySide 1.1.0-based application, and have been looking for good examples to look at for unit and functional testing my application. I want to be able to do functional testing of the UI (simulating clicks, key presses, etc), unit testing of UI slots that alter the layout of the UI (presumably using a partially-mocked sender and receiver), as well as unit testing of code that involves widgets, but without requiring any windows to be rendered. As one example, I dynamically create

问题 Would like to get calendar data from page like http://www.dukascopy.com/swiss/english/marketwatch/calendars/eccalendar/ The data is dynamic and loads with js-applet - "DukascopyApplet" I tried to extract data this way: app = QApplication(sys.argv) web = QWebView() web.page().mainFrame().loadFinished.connect(print_content) web.load(QUrl("http://www.dukascopy.com/swiss/english/marketwatch/calendars/eccalendar/")) web.show() frame = web.page().mainFrame() print(frame.evaluateJavaScript(
