在我的程序中，我有一个主窗口，我想在该主窗口初始化之前添加一个加载窗口，但是我无法为此加载窗口添加图标。那里是我的代码：
from tkinter import *
import tkinter.ttk as ttk
root = Tk()
root.withdraw()
root.title('BINGO')
class Loader():
def __init__(self):
self.loader = Tk()
try:
img = PhotoImage(r'C:\menu-16.png')
self.loader.tk.call('wm', 'iconphoto', self.loader._w, img)
except:
self.loader.attributes('-toolwindow', True)
self.loader.title('BINGO')
self.frame = LabelFrame(self.loader)
self.frame.pack(fill=BOTH, pady=2,padx=2)
self.label = Label(self.frame, text='Loading...', font=('segoe', 12))
self.label.pack(side=TOP, pady='4')
self.progress_bar = ttk.Progressbar(self.frame, mode='determinate', length=464)
self.progress_bar.pack(side=TOP, fill='x', pady='20')
self.loader.update()
def bar(self, value):
self.progress_bar['value'] += value
self.loader.update()
def destroy(self):
self.loader.destroy()
loader = Loader()
loader.bar(5)
class Main_Window():
def __init__(self):
self.mframe = LabelFrame(root)
pass
loader.bar(100)
root.tk.call('wm', 'iconphoto', root._w, PhotoImage(r'C:\menu-16.png'))
loader.destroy()
Application = Main_Window()
root.mainloop()
在这种情况下，“装载程序”作为工具窗口运行而没有图标，但主“ Main_window”拥有它。该如何解决？

我已经确定了解决问题的方法：self.loader = Tk() 编辑 到 self.loader = Toplevel()

检查您的代码。进度栏是在class Temp {
constructor() {
Object.defineProperty(this, "hi", {
value: () => {
//
},
writable: true,
configurable: true,
enumerable: true
});
}
}
中定义的，因此您需要将 from queue import Queue
import threading
import time
queue1 = Queue()
# this function should finish its work and restart with fresh queue1
def association_helper():
# this program should get the whole data from the queue, add into the list and print it. again it starts with
# remaining items in queue (the items which was inserting when this function printings the value)
lock = threading.Lock()
lock.acquire()
items = []
print("Start..")
while True:
if queue1.qsize()>0:
print("Line no 13:", queue1.qsize())
SizeofQueue1 = queue1.qsize()
for i in range(SizeofQueue1):
items.append(queue1.get())
queue1.task_done()
print("Line no 19:", len(items))
print(items)
print("Line no 25: done")
time.sleep(0.1)
lock.release()
i = 0
def main():
global i
# continuous data coming and adding in queue
while True:
queue1.put([i])
i += 1
if __name__ == '__main__':
# main thread will always run (adding the items in the queue)
f_thread = threading.Thread(target=association_helper)
f_thread.daemon = True
f_thread.start()
main()
output:
Start...
Line no 13: 1415
Line no 19: 3794
Line no 25: done
Line no 13: 40591
Line no 19: 41856
Line no 25: done
Line no 13: 78526
as per expectations, the line no 13 and line no 19 should be same. also, after, line no 25, it should print Start..(because association_helps should finish its execution and run again)
导入为
tkinter.tkk因为有一个额外的tkinter.tkk，请删除from tkinter import *
from tkinter.ttk import *
....
img = PhotoImage(r'C:\menu-16.png'))
...
root.tk.call('wm', 'iconphoto', root._w, PhotoImage(r'C:\menu-16.png'))
并将)添加到PhotoImage并从)中删除file=。
ttk并且您已将类定义为ttk.Progressbar，并且正在将其调用为img = PhotoImage(file=r'C:\menu-16.png')
....
root.tk.call('wm', 'iconphoto', root._w, PhotoImage(file=r'C:\menu-16.png'))
。
