输入Tkinter（Python）后的Recenter文本

我现在正在使用Tkinter for Python，并且试图找出在用户向Text小部件中输入内容后是否有可能重新接收文本。输入Tkinter（Python）后的Recenter文本

目前，我的代码的输出是这样的：

我想是针对输入的文本显示的文本字段中居中。我的代码如下。所有的文本条目基本相同，因此大部分代码是相似的。我只是将它包含在内，但我确定它只是需要处理修改Text（...）对象。

谢谢。

我看到你在代码中重复了很多次。尝试为您的输入创建函数或类。它将使您的代码更具可读性并减少行数。更可读的代码将使更多的人能够帮助:)另外，将你的导入放入你的代码中，以便人们可以自己测试你的代码。 –

使用多行文本小部件进行单行输入的原因是什么？ –

@BryanOakley在某些时候，我需要它来处理某些功能无法处理的功能，但我现在对这个理由消隐了。我可以改变它，但我记得有一个很好的理由（权重/间距可能）来改变它。 – RWA4ARC

假设你不能使用Entry部件具有内置justify属性，也许是最简单的解决方案是增加上重新标签的插件的数据任意键释放绑定：

def retag(event): 
    event.widget.tag_add("tag-center", "1.0", "end") 
... 
bdFileNameEntry.bind("<Any-KeyRelease>", retag)
