如何在 PyQt5 中保存更改的文本

  • 772

我有一个代码，当单击“下一步”按钮时，文本会发生变化，我怎样才能让它保存以及下次出现更改的文本？我的代码：

import sys
from PyQt5 import QtWidgets, QtGui, QtCore, QtMultimedia
from PyQt5.Qt import *

MyApp = QtWidgets.QApplication(sys.argv)
V = MyApp.desktop().screenGeometry()
h = V.height()
w = V.width()
try:
    from PyQt5.QtWinExtras import QtWin
    myappid = 'mycompany.myproduct.subproduct.version'
    QtWin.setCurrentProcessExplicitAppUserModelID(myappid)
except ImportError:
    pass

    您需要通过读取文件并将更改保存到文件来设置文本

    此问题的可能解决方案示例：

    from PyQt5 import QtCore, QtGui, QtWidgets


class Example(QtWidgets.QMainWindow):
    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        self.label = QtWidgets.QLabel(self)
        self.label.setGeometry(QtCore.QRect(155, 118, 90, 18))
        self.pushButton = QtWidgets.QPushButton(self)
        self.pushButton.setGeometry(QtCore.QRect(153, 253, 94, 29))
        self.pushButton.setText('Изменить')
        self.pushButton.clicked.connect(self.change)
        self.pushButton.click()

        self.resize(400, 400)
        self.show()

    def change(self):
        with open('test.txt', 'r') as f:
            text = f.read()
            self.label.setText('Старый текст' if  text == '' else text)
            if text == '':
                with open('test.txt', 'w') as f:
                    f.write('Новый текст')


if __name__ == '__main__':
    import sys
    app = QtWidgets.QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())
