Как обратится к ‘name’ объектов PyQt через цикл c подменой цифры в имени объекта?
Как обратиться к имени объектов, например label_1 , label_2 , label_3 ,
где будет перебирать цикл элементы через id переменную self.label_( id ).setText() ? Есть у данного способа минусы и посоветуете ли вы так делать?

Inspired by Test-Driven Development with Python by Harry Percival, I’m trying to implement functional testing of a PyQt GUI. I’m finding that, in order for tests to find the GUI components, I need the actual code to include lots of .setObjectName lines as a «hook». This makes the actual program code very redundant. For example:
modelsWidget = QWidget() modelsWidget.setObjectName('modelswidget') modelsLayout = QVBoxLayout() modelsLayout.setObjectName('modelslayout') twoSingletButton = QRadioButton('Two uncoupled spin-1/2 nuclei') twoSingletButton.setObjectName('twosingletbutton') abButton = QRadioButton('Two coupled spin-1/2 nuclei\n ("AB quartet)') abButton.setObjectName('abbutton')
and then the functional tests would look up components by name, e.g.:
def test_view_switch(self): """The user clicks on the radio button for the AB model, and sees that the view has changed to that for the AB model.""" initialView = self.ui.stackedWidget.currentWidget() abButton = self.getToolbar.findChild(QRadioButton, 'abbutton') abButton.click() finalView = self.ui.stackedWidget.currentWidget() assert initialView is not finalView assert finalView.objectName() == 'ABwidget' (OK, that’s probably poor craftsmanship, with two asserts in a single test, but it demonstrates the nature of the test strategy.) I don’t see a good way around this. It’s a lot more direct to use a statement such as:
self.Gui.findChild (QDoubleSpinBox, 'va') self.Gui.stackedWidget.currentWidget.layout.itemAtPosition(2, i).widget() in the tests. The former is assuming that the main code uses the same widget names, and the latter is assuming that the main code uses the exact same hierarchy to place a widget. Neither may truly be mandatory to provide the desired «look/feel» of the GUI. Am I going about functional testing a PyQt GUI the wrong way? Is there a more proper way for a test to find, or refer to, GUI components?

PyQt — пару вопросов
Всем привет, у меня возникла проблема при работе с PyQt, создаю форму в Qt Designer:
перегоняю её в код Питона командой:
pyuic4.bat face.ui > face.py
генерится следующий код в вайл face.py:
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'D:\Python\QT\face.ui'
#
# Created: Tue May 29 16:13:47 2007
# by: PyQt4 UI code generator 4.2
#
# WARNING! All changes made in this file will be lost!

запускаю все следующим кодом:
import sys
from face import Ui_MainWindow
from PyQt4 import QtCore, QtGui
class WellForm(QtGui.QWidget):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
fmMain = WellForm()
fmMain.show()
sys.exit(app.exec_())
врезультате, мне приходится коментить 3 строки в коде face.py чтобы запустилось, но вид сильно колбасится. Не знаете, что нитак?

Как обновлять окно PyQt во время выполнения длительного цикла из другого модуля
Вы используете устаревший браузер. Этот и другие сайты могут отображаться в нем неправильно.
Необходимо обновить браузер или попробовать использовать другой.

Привет, я тут первый раз, надеюсь на научение и помощь. Сделал простой демонстрационный пример, где есть приложение, в котором по нажатию кнопки запускается функция, она должна выводить сообщение в окно, она вроде выводит, но проблема в том, что делает это не на каждой итерации, а лишь при полном окончании исполнения. Научите, пожалуйста, обновлять окно после каждого вывода сообщения. Спасибо.
