Question

我正在使用Python 3和Qt5。我设计了一个QWidget，只有700多个QLabel。我需要更改它们，但我想这样做而不必写超过700行来为我的所有标签设置文本。我还需要随意展示和隐藏它们。

如果我有一个该变量名称的字符串，是否可以对它们进行分组或编辑变量？我正在寻找类似Matlab'assignin'功能的东西。

标签名为label_A - label_Z和label_AA - label_ZZ

来自主课程导入ezodf

self.ui = AnalysisGui.Ui_Form()
self.ui.setupUi(self)

self.Alphabet = ["a", "b", "c", "d", "e",
                 "f", "g", "h", "i", "j",
                 "k", "l", "m", "n", "o",
                 "p", "q", "r", "s", "t",
                 "u", "v", "w", "x", "y", "z"]

for Alpha in self.Alphabet:
    self.ui.findChild(QtGui.QLabel, "label_"+Alpha.upper()).SetText(Alpha.upper()+" ")
    for Beta in self.Alphabet:
        self.ui.findChild(QtGui.QLabel, "label_"+Alpha.upper()+Beta.upper()).SetText(Alpha.upper()+Beta.upper()+" ")

这是来自AnalysisGui类，显示了如何定义标签

self.label_A = QtGui.QLabel(Form)
self.label_A.setStyleSheet(_fromUtf8("color: rgb(0, 0, 0);\n""font: 8pt \"Calibri\";\n""background-image: url(:/Thoth/SeeThrough.png);"))
self.label_A.setObjectName(_fromUtf8("label_A"))
self.gridLayout.addWidget(self.label_A, 1, 0, 1, 1)
self.label_B = QtGui.QLabel(Form)
self.label_B.setStyleSheet(_fromUtf8("color: rgb(0, 0, 0);\n""font: 8pt \"Calibri\";\n""background-image: url(:/Thoth/SeeThrough.png);"))
self.label_B.setObjectName(_fromUtf8("label_B"))
self.gridLayout.addWidget(self.label_B, 1, 1, 1, 1)
self.label_C = QtGui.QLabel(Form)
self.label_C.setStyleSheet(_fromUtf8("color: rgb(0, 0, 0);\n""font: 8pt \"Calibri\";\n""background-image: url(:/Thoth/SeeThrough.png);"))
self.label_C.setObjectName(_fromUtf8("label_C"))
self.gridLayout.addWidget(self.label_C, 1, 2, 1, 1)

感谢您的帮助。

您可以尝试使用QWidget.findChild

import sys
from PyQt4.QtGui import *
try:
    from PyQt4.QtWidgets import *
except ImportError:
    pass


app = QApplication(sys.argv)

window = QWidget()
layout = QVBoxLayout()

for i in range(26):
    title = chr(ord('A')+i)
    label = QLabel(title, window)
    label.setObjectName("label_"+title)
    layout.addWidget(label)

window.findChild(QLabel, "label_F").setText("test")

window.setLayout(layout)
window.show()

app.exec_()

更改许多QLabel的QLabel文本
