将文本变量传递给Tkinker GUI中的标签？

  • 时间:
  • 分类: Python

我正在试着组装这个图形用户界面，这是我的第一次尝试。它主要是我从到处找到的样本中拼凑而成的代码拼贴画。
到目前为止，一切都很好，只是我似乎不知道如何将"文本变量"从数组传递到标签。
#如果您转到def printLabels(Self)，并def on_move()，您将明白我的意思：)，
万分感谢。(我刚刚开始学习#程序，抱歉弄得一团糟！)

# 回答1


有两种方法可以更新标签。使用小部件方法
W.CONFIG()
在中重新分配新标签的步骤
ON_CLICK()
方法。或者，创建Tkinter.StringVar对象并配置Tkinter.Label对象的关键字
文本变量
而不是
文本
并将其赋给适当的变量。使用以下命令重新赋值变量
字符串变量
方法
Set()
在你的
ON_CLICK()
方法。
# 回答2


下面是一个使用
Tkinter.StringVar
与一个
Tkinter.Label
。
