In PyQt5, there are several ways to handle user input:<\/p>\n

    \n
  1. Create a single-line text input box using the QLineEdit class, where users can input text. Retrieve the input text using the text() method.<\/li>\n<\/ol>\n
    from<\/span> PyQt5.QtWidgets import<\/span> QApplication, QLineEdit\r\n\r\n# \u521b\u5efa\u4e00\u4e2a\u5e94\u7528\u7a0b\u5e8f\u5bf9\u8c61<\/span>\r\napp = QApplication([])\r\n\r\n# \u521b\u5efa\u4e00\u4e2a\u5355\u884c\u6587\u672c\u8f93\u5165\u6846<\/span>\r\nline_edit = QLineEdit()\r\nline_edit.show()\r\n\r\n# \u83b7\u53d6\u7528\u6237\u8f93\u5165\u7684\u6587\u672c\u5185\u5bb9<\/span>\r\ntext = line_edit.text()\r\n<\/code><\/pre>\n
      \n
    1. QTextEdit: Create a multi-line text input box using the QTextEdit class, where users can input text on multiple lines. Retrieve the user’s input text content using the toPlainText() method.<\/li>\n<\/ol>\n
      from<\/span> PyQt5.QtWidgets import<\/span> QApplication, QTextEdit\r\n\r\n# \u521b\u5efa\u4e00\u4e2a\u5e94\u7528\u7a0b\u5e8f\u5bf9\u8c61<\/span>\r\napp = QApplication([])\r\n\r\n# \u521b\u5efa\u4e00\u4e2a\u591a\u884c\u6587\u672c\u8f93\u5165\u6846<\/span>\r\ntext_edit = QTextEdit()\r\ntext_edit.show()\r\n\r\n# \u83b7\u53d6\u7528\u6237\u8f93\u5165\u7684\u6587\u672c\u5185\u5bb9<\/span>\r\ntext = text_edit.toPlainText()\r\n<\/code><\/pre>\n
        \n
      1. Create a button using the QPushButton class that users can click to trigger an event. Use the clicked.connect() method to connect slots for handling user input.<\/li>\n<\/ol>\n
        from<\/span> PyQt5.QtWidgets import<\/span> QApplication, QPushButton\r\n\r\ndef<\/span> handle_button_click<\/span>():\r\n    print<\/span>(\"Button clicked\"<\/span>)\r\n\r\n# \u521b\u5efa\u4e00\u4e2a\u5e94\u7528\u7a0b\u5e8f\u5bf9\u8c61<\/span>\r\napp = QApplication([])\r\n\r\n# \u521b\u5efa\u4e00\u4e2a\u6309\u94ae<\/span>\r\nbutton = QPushButton(\"Click me\"<\/span>)\r\nbutton.show()\r\n\r\n# \u8fde\u63a5\u6309\u94ae\u70b9\u51fb\u4e8b\u4ef6\u7684\u69fd\u51fd\u6570<\/span>\r\nbutton.clicked.connect(handle_button_click)\r\n<\/code><\/pre>\n
