问题描述
当我在 thread (t = Thread (target = self._configure_clicked) 的目标中遇到错误时，它会出现在终端 "Execption in thread Thread-1" 上（我的代码中有更多线程）。
如果出现错误，并且没有错误“messageBox.showinfo”，我希望出现“messageBox.showerror”。我该怎么做？
我附上了 GUI 代码和终端屏幕的摘录
from tkinter import * # importo tutto da tkinter
from tkinter import messageBox,ttk
from threading import Thread
import multi_sensor_acc_gyro1 as multi ##other script.py
...
...
def configure_clicked(self):
t=Thread(target=self._configure_clicked,daemon=True)
t.start()
...
self.pb.start() #progress bar start
while t.is_alive():
self.pb.update() #progress bar update
...
messageBox.showinfo("CONfigURE clicked","the sensors have been configured\n\\n click OK to continue")
messageBox.showerror("Error","sensor disconnection")
...
...
def _configure_clicked(self):
mac_address=["F7:64:55:AD:0A:19","F2:A1:3A:E2:F2:ED","F9:8E:32:DD:1A:EB"]
output_1=multi.configure(mac_address)
self.states=output_1[0]
self.loggers_acc=output_1[1]
self.loggers_gyro=output_1[2]
...
我尝试使用 try / except，但我做错了。我没有检测到任何错误：
from tkinter import * # importo tutto da tkinter
from tkinter import messageBox,ttk
from threading import Thread
from PIL import Image
import multi_sensor_acc_gyro1 as multi
...
...
def configure_clicked(self):
try:
t=Thread(target=self._configure_clicked,daemon=True)
t.start()
...
self.pb.start()
while t.is_alive():
self.pb.update()
...
messageBox.showinfo("CONfigURE clicked","the sensors have been configured\n\\n click OK to continue")
...
...
except:
messageBox.showerror("Error","sensor disconnection")
def _configure_clicked(self):
mac_address=["F7:64:55:AD:0A:19","F9:8E:32:DD:1A:EB"]
output_1=multi.configure(mac_address)
self.states=output_1[0]
self.loggers_acc=output_1[1]
self.loggers_gyro=output_1[2]
...
...
