输入Tkinter后的Recenter文本（Python）

Question

我现在正在使用Tkinter for Python，我试图弄清楚在用户向Text小部件输入内容后是否可以重新输入文本。

目前，我的代码输出如下：

我想要的是输入的文本在文本字段中居中显示。我的代码如下。所有文本条目基本相同，因此大多数代码都是相似的。我只是为了全面而包含它，但我很确定它只需要处理修改Text（...）对象。

谢谢。

假设您无法使用具有内置Entry属性的justify窗口小部件，或许最简单的解决方案是在任何重新标记数据的密钥版本上添加绑定在小部件中：

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