这里假设要求用户输入数字ifinput_text.isdigit():returnTrueelse:returnFalse# 创建验证器validate=root.register(validate_input)# 绑定验证函数entry.config(validate="key",validatecommand
If theisnumeric()method returnsFalse, theelseblock is executed, printing a message to notify the user that the input is not an integer and prompting them to enter a valid integer. This approach is particularly useful when the objective is to validate a string without the need for exception ...
步骤4:设置Text组件的validatecommand属性 现在我们需要将步骤3中创建的函数与Text组件的validatecommand属性相关联。这将使Tkinter在每次用户尝试输入文本时调用我们的函数。 # 设置Text组件的validatecommand属性text_box.configure(validate="all",validatecommand=(validate_input,"%d","%i","%P","%s","%S","%v"...
