如何在 GUI 按钮按下时启动 while 循环？

Question

我正在寻找一种在按下按钮时启动 while 循环的方法，在本例中是名为“start_loop”的按钮。我非常想知道这是如何完成的，并感谢您在完成此过程中提供的任何帮助，谢谢！

这是完整的 Python 脚本：

from tkinter import *
import win32api
import win32con
from tkinter import messagebox


# defining click as setting the position and starting a click and ending a click
def click(x, y):

    win32api.SetCursorPos((x, y))
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN, x, y, 0, 0)
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP, x, y, 0,  0)

# Creation of the GUI below

root = Tk()
root.geometry('315x250+250+250')  # 315x250 and 250 pixels in x and y direction
root.title("Buffet Time's Auto-Clicker")

# Click
click_label = Label(text='Enter # of clicks here:', fg='green').place(x=30, y=30)
click_entry = Entry().place(x=150, y=30)

# X
x_label = Label(text='Enter the x coordinate here:', fg='black').place(x=30, y=75)
x_entry = Entry().place(x=150, y=75)

# Y
y_label = Label(text='Enter the y coordinate here:', fg='blue').place(x=30,     y=120)
y_entry = Entry().place(x=150, y=120)

# Start the loop button
start_loop = Button(text='Press to Start', fg='yellow', bg='black').place(x=110,    y=175)


# prompts user before quitting
def on_closing():
    if messagebox.askokcancel("Quit", "Do you want to quit?"):
        root.destroy()
root.protocol("WM_DELETE_WINDOW", on_closing)

root.mainloop()

num_of_clicks = click_entry.get()
x_coord = x_entry.get()
y_coord = y_entry.get()


# while loop for the clicking
counter = 0
try:
    while counter < num_of_clicks:
        click(x_coord, y_coord)  # 230, 475 for cookie clicker

        if win32api.GetAsyncKeyState(ord('X')):
            break
        counter += 1
except KeyboardInterrupt:
    pass

Answer 1

您需要将“command”关键字传递给 Button 构造函数：

start_loop = Button(root, text='Press to Start', fg='yellow', bg='black', command=self.myButtonHandler).place(x=110, y=175)

并定义一个函数 myButtonHandler(frame)，每次按下按钮时都会调用该函数，因此计数器会加 1。

这就是你所追求的吗？循环隐藏在 root.mainloop 中，您不必自己编写循环。您的退出按钮的命令应该是 frame.quit
