【中文标题】PyQt5:如何将回溯显示到小部件中?【英文标题】:PyQt5: How to display traceback(s) into a Widget? 【发布时间】:2021-01-19 06:55:24 【问题描述】:我将错误显示到QPlainTextEdit
或任何其他更适合的小部件。
code.py:
import traceback
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(394, 185)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.plntxt = QtWidgets.QPlainTextEdit(self.centralwidget)
self.plntxt.setGeometry(QtCore.QRect(10, 10, 371, 131))
self.plntxt.setObjectName("plntxt")
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
self.m()
def m(self):
try:
sdhfha #to create error that will be displayed to GUI
except Exception as a:
#I'm trying to pass the error named a into the PlainTextEdit
self.plntxt.setPlainText(a)
pass
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
错误是:
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "C:\Users\???\AppData\Local\Programs\Python\Python38\Lib\site-packages\PySide2\???...
TypeError: setPlainText(self, str): argument 1 has unexpected type 'NameError'
[Finished in 0.4s]
有什么想法吗?
【问题讨论】:
【参考方案1】:您必须将异常转换为字符串:
def m(self):
try:
sdhfha
except Exception as a:
self.plntxt.setPlainText(str(a))
