Tkinter文本小部件。取消选择文字

我使用了一个带有Tkinter的文本小部件,当按下按钮时,它会将所选文本复制到剪贴板。现在在复制过程之后我想取消选择文本。 知道这可能有用吗?

由于似乎有必要发布一些代码,让人们更详细地了解我的问题,这里是:

def copy_to_clipboard(self, copy_string):
    #copy to clipboard function
    self.clipboard_clear()
    try:
        #text in outputlistfield marked, so copy that
        self.clipboard_append(self.outputlistfield.get("sel.first", "sel.last"))
    except:
        #no text marked

outputlistfield是一个文本小部件。如果选择了文本,则应将其复制到剪贴板。这很好。但是我想重置选择,以便在复制文本后不再选择文本。那么,有什么建议吗?

self.outputlistfield.tag_remove(SEL, "1.0", END)可以解决问题。如下例所示:

from tkinter import ttk
from tkinter import *

class Main(Tk):
    def __init__(self, *args, **kwargs):
        Tk.__init__(self, *args, **kwargs)  
        self.title("Test")

        self.text = Text(self)
        self.text.insert(END, "This is long long text, suitable for selection and copy.")
        self.text.pack(expand=True, fill=BOTH)

        self.frame = ttk.Frame(self)
        self.frame.pack(expand=True, fill=BOTH)

        self.button1 = ttk.Button(self.frame, text="Copy", command=self.OnCopy)
        self.button1.pack(expand=True, fill=BOTH)

        self.button2 = ttk.Button(self.frame, text="Copy & Unselect", command=self.OnCopyDeselect)
        self.button2.pack(expand=True, fill=BOTH)

    def OnCopy(self):
        try:
            text = self.text.selection_get()
        except TclError:
            print("Select something")
        else:
            self.clipboard_clear()
            self.clipboard_append(text)
        self.text.focus()

    def OnCopyDeselect(self):
        self.OnCopy()
        self.text.tag_remove(SEL, "1.0", END)

root = Main()
root.mainloop()

最简单的最简单解决方案是在附加到剪贴板后立即使用{text widget} .tag_remove(Tkinter.SEL,'1.0',Tkinter.END)从整个文本小部件中删除“SEL”标记。修改后的代码(带有一个#NEW LINE,特定于您的代码)如下:

def copy_to_clipboard(self, copy_string):
    #copy to clipboard function
    self.clipboard_clear()
    try:
        #text in outputlistfield marked, so copy that
        self.clipboard_append(self.outputlistfield.get("sel.first", "sel.last"))
        self.outputlistfield.tag_remove("sel", "sel.first", "sel.last") #NEW LINE
    except:
        #no text marked
