我已经在python中使用Tkinter创建了一个程序，将普通文本转换为一些奇特的文本。自动将Tkinter文本小部件内容复制到剪贴板？
我在想，如果有可能的输出一次“转换”按钮被按下自动复制到剪贴板。
这里是我的代码：
#Importing TKinter module
from tkinter import *
#Setting up the GUI window
win = Tk()
win.title("Font Converter")
win.resizable(0,0)
#Converting
def replace():
text = entry.get("1.0",END)
replacements = {
#Upper case letters
"A": "Ａ",
"B": "Ｂ",
"C": "Ｃ",
"D": "Ｄ",
"E": "Ｅ",
"F": "Ｆ",
"G": "Ｇ",
"H": "Ｈ",
"I": "Ｉ",
"J": "Ｊ",
"K": "Ｋ",
"L": "Ｌ",
"M": "Ｍ",
"N": "Ｎ",
"O": "Ｏ",
"P": "Ｐ",
"Q": "Ｑ",
"R": "Ｒ",
"S": "Ｓ",
"T": "Ｔ",
"U": "Ｕ",
"V": "Ｖ",
"W": "Ｗ",
"X": "Ｘ",
"Y": "Ｙ",
"Z": "Ｚ",
#Lower case letters
"a": "ａ",
"b": "ｂ",
"c": "ｃ",
"d": "ｄ",
"e": "ｅ",
"f": "ｆ",
"g": "ｇ",
"h": "ｈ",
"i": "ｉ",
"j": "ｊ",
"k": "ｋ",
"l": "ｌ",
"m": "ｍ",
"n": "ｎ",
"o": "ｏ",
"p": "ｐ",
"q": "ｑ",
"r": "ｒ",
"s": "ｓ",
"t": "ｔ",
"u": "ｕ",
"v": "ｖ",
"w": "ｗ",
"x": "ｘ",
"y": "ｙ",
"z": "ｚ",
#Numbers
"1": "１",
"2": "２",
"3": "３",
"4": "４",
"5": "５",
"6": "６",
"7": "７",
"8": "８",
"9": "９",
"0": "０",
}
text = "".join([replacements.get(c, c) for c in text])
output.delete('1.0', END)
output.insert(END, str(text))
#Text Variables
enter = StringVar()
#Creating the widgets
l1 = Label(win, text="Enter text:")
entry = Text(win, width=50, height=3, wrap=WORD)
button = Button(win, text="Convert", width=20)
l2 = Label(win, text="Converted text:")
output = Text(win, width=50, height=3, wrap=WORD)
#Positioning the widgets
l1.grid(row=1, column=1, padx=5, sticky=W)
entry.grid(row=2, column=1, columnspan=2, padx=5, pady=(0,10))
button.grid(row=3, column=1, columnspan=2, pady=5)
l2.grid(row=4, column=1, padx=5, sticky=W)
output.grid(row=5, column=1, columnspan=2, padx=5, pady=(0,10))
#Button activation
button.configure(command=replace)
#So the program is on repeat
win.mainloop()
请原谅大量的低效率，我还是相当多的小白，当谈到蟒蛇。

代码:
from tkinter import *
from tkinter.ttk import *
import time
scale = 100
def running():                   # 开始Progressbar动画
    btn.configure(text="系统忙碌中...",state=DISABLED)
    print("\n"*2)
    print("执行开始".center(scale+28,'-'))
    start = time.perf_counter()
    for i in range(scale+1):
        pb["value"] = i      # 每次更新1
        root.update()            # 更新画面
        a = '*' * i
        b = '.' * (scale - i)
        c = (i/scale)*100
        t = time.perf_counter() - start
        print("\r任务进度:{:>3.0f}% [{}->{}]消耗时间:{:.2f}s".format(c,a,b,t),end="")
        time.sleep(0.03)
    print("\n"+"执行结束".center(scale+28,'-'))
    btn.configure(text="重启任务",state=NORMAL)

root = Tk()
root.geometry("300x140+600+300")
root.title("任务进度可视化")

# 使用默认设置创建进度条
pb = Progressbar(root,length=200,mode="determinate",orient=HORIZONTAL)
pb.pack(padx=10,pady=20)
pb["maximum"] = 100
pb["value"] = 0

btn = Button(root,text="启动任务",command=running)
btn.pack(pady=10)

root.mainloop() 

运行效果截图:

关于重定向的知识可以参考这篇Python标准输出重定向
程序入口

0927.py
import sys
import tkinter
from func import demo0929


class myStdout():	# 重定向类
    def __init__(self):
    	# 将其备份
        self.stdoutbak = sys.stdout		
        self.stderrbak = sys.stderr
        # 重定向
        sys.stdout = self
        sys.stderr = self

    def write(self, info):
        # info信息即标准输出sys.stdout和sys.stderr接收到的输出信息
        t.insert('end', info)	# 在多行文本控件最后一行插入print信息
        t.update()	# 更新显示的文本，不加这句插入的信息无法显示
        t.see(tkinter.END)	# 始终显示最后一行，不加这句，当文本溢出控件最后一行时，不会自动显示最后一行

    def restoreStd(self):
        # 恢复标准输出
        sys.stdout = self.stdoutbak
        sys.stderr = self.stderrbak
        

def btn_func():
	"""按键的触发事件"""
    demo0929.func()


mystd = myStdout()	# 实例化重定向类
window = tkinter.Tk()	# 实例化tk对象
t = tkinter.Text(window)	# 创建多行文本控件
t.pack()	# 布局在窗体上

b = tkinter.Button(window, text='start', command=btn_func)	# 创建按钮控件，并绑定触发事件
b.pack()	# 布局在窗体上


window.mainloop()	# 显示窗体
mystd.restoreStd()	# 恢复标准输出


按键触发事件

每隔一秒打印一个数字。

demo0929.py
import time

def func():
    for i in range(5):
        print(i)
        # t.insert('end', i)
        time.sleep(1)


效果如图

我将Tkinter文本框设置为显示文件的内容.示例行如下：
SUCCESS - Downloaded example.jpg
File was 13KB in size
我想做的是让包含“ SUCCESS”一词的任何行的文本颜色更改为蓝色.请注意,我需要使它具有动态性,因为在一个文件中可以找到数百个单词,并且无法预测其位置.
这是我用来将文件内容输出到文本框中的代码.哪个工作正常.
log = open(logFile, 'r')
while 1:
line = log.readline()
if len(line) == 0:
break
else:
self.txtLog.insert(Tkinter.END, line)
self.txtLog.insert(Tkinter.END, os.linesep)
log.close()
我试图像下面的示例行那样使用tag_add和tag_config,但无济于事.
`self.txtLog.tag_add("success", "1.0", "1.8")
self.txtLog.tag_config("success", foreground="blue")`
`
解决方法:
您需要配置标签,并在将文本添加到末尾时指定该标签.
这应该可以工作(尽管未经测试)：
self.txtLog.tag_config("success", foreground="blue", font="Arial 10 italic")
log = open(logFile, 'r')
while 1:
line = log.readline()
if len(line) == 0:
break
else:
tags = ("success",) if line.startswith("SUCCESS") else None
self.txtLog.insert(Tkinter.END, line+os.linesep, tags)
log.close()
另外,我只是注意到您在tag_config之前使用了tag_add,我认为应该相反.
