【为Python图形界面添加自定义函数功能】最终效果
定义一个函数获取图形界面输入的内容并将输入的中文转为Unicode后显示到图形界面

def to_unicode(self):# 获取中文文本框内容value_text=self.textEdit.toPlainText()print('输入的中文内容为:{}'.format(value_text))# 转为Unicodeunicode_text=value_text.encode("unicode_escape")print('输入内容的Unicode为:{}'.format(unicode_text))# 通过textBrowser进行展示# self.textBrowser.setPlainText(str(unicode_text).replace("b", ""))self.textBrowser.setPlainText(str(unicode_text).strip("b'"))

self.pushButton.clicked.connect(self.to_unicode)# 设置按钮的功能函数修改后的全代码main.py

import sysfrom 中文转Unicode import Ui_MainWindowfrom PyQt5.QtWidgets import QApplication,QMainWindowif __name__ == '__main__':app=QApplication(sys.argv)mainWindow = QMainWindow()ui=Ui_MainWindow()# 向主窗口上添加控件ui.setupUi(mainWindow)mainWindow.show()sys.exit(app.exec_())
