定義一個函式獲取圖形介面輸入的內容並將輸入的中文轉為Unicode後顯示到圖形介面

 def to_unicode(self): # 獲取中文文字框內容 value_text=self.textEdit.toPlainText() print('輸入的中文內容為:{}'.format(value_text)) # 轉為Unicode unicode_text=value_text.encode("unicode_escape") print('輸入內容的Unicode為:{}'.format(unicode_text)) # 通過textBrowser進行展示 # self.textBrowser.setPlainText(str(unicode_text).replace("b", "")) self.textBrowser.setPlainText(str(unicode_text).strip("b'"))

self.pushButton.clicked.connect(self.to_unicode)# 設定按鈕的功能函式
