文字框控制元件具有 delete(first, last=None)
方法,可從文字框中刪除 first
索引處或 (first, last)
範圍內的字元。
如果未給出 last
,則僅刪除在 first
位置中指定的字元。
清除 Tkinter 文字控制元件內容的示例程式碼
import tkinter as tk
root = tk.Tk()
root.geometry("400x240")
def clearTextInput():
textExample.delete("1.0","end")
textExample=tk.Text(root, height=10)
textExample.pack()
btnRead=tk.Button(root, height=1, width=10, text="Clear",
command=clearTextInput)
btnRead.pack()
root.mainloop()
textExample.get("1.0", "end")
"1.0"
和"end"
是指 Tkinter 文字框控制元件中內容的第一個字元和最後一個字元,與如何獲取文字的輸入的文章中介紹的內容相同。
