import matplotlib.pyplot as plt
from matplotlib.widgets import Button
def clicked(event):
print("Button pressed")
button_pos = plt.axes([0.2, 0.9, 0.1, 0.075])
b1 = Button(button_pos, 'Button1')
b1.on_clicked(clicked)
button_pos = plt.axes([0.2, 0.8, 0.1, 0.075])
b2 = Button(button_pos, 'Button2')
b2.on_clicked(clicked)
plt.show()
import matplotlib.pyplot as plt
from matplotlib.widgets import Button
def clicked(event, text):
print("Button pressed"+text)
button_pos = plt.axes([0.2, 0.9, 0.1, 0.075])
b1 = Button(button_pos, 'Button1')
b1.on_clicked(clicked(text=" its the first"))
button_pos = plt.axes([0.2, 0.8, 0.1, 0.075])
b2 = Button(button_pos, 'Button2')
b2.on_clicked(clicked)
b2.on_clicked(clicked(text=" its the second"))
plt.show()
但通过该更改,我得到以下错误消息:
Traceback (most recent call last):
File "/bla/main.py", line 24, in <module>
b1.on_clicked(clicked(text=" its the first"))
TypeError: clicked() missing 1 required positional argument: 'event'
它们是在这样一个函数中放入第二个参数的一种方式,还是在Python中需要在这种情况下生成两个单击的函数?
