【问题描述】：

有没有办法让 GUI 中的文本框具有默认文本显示？

我希望文本框有“请设置你想要的文件的路径...” 但是，当我运行它时 - 它是空白的......

我的代码如下：

  path=StringVar()
  textEntry=Entry(master,textvariable=path,text='Please set the path of the file you want...')
  textEntry.pack()

【解决方案1】：

这应该演示如何做你想做的事：

import Tkinter as tk

root = tk.Tk()

entry = tk.Entry(root, width=40)
entry.pack()
# Put text in the entrybox with the insert method.
# The 0 means "at the begining".
entry.insert(0, 'Please set the path of the file you want...')

text = tk.Text(root, width=45, height=5)
text.pack()
# Textboxes also have an insert.
# However, since they have a height and a width, you need to
# put 0.0 to spcify the beginning.  That is basically the same as
# x=0, y=0.
text.insert(0.0, 'Please set the path of the file you want...')

root.mainloop()

【解决方案2】：

path.set("Please set the path of the file you want...")

-或-

textEntry.insert(0, "Please set the path of the file you want...")
