python - Pycharm doesn't show error information for `PyQt5` program (e.g. `TypeError`) -


in pycharm 4.5.2, if had error in pyqt5 slots, when slots called, pycharm shows process finished exit code 1, not , why error happends. doesn't happen when error in __init__.
makes difficult debug. how fix this?

this widget generated qt designer

for example, if wrote button.settext('a'+1) when clicked on button:

# -*- coding: utf-8 -*-  import sys pyqt5 import qt test import ui_form  application = qt.qapplication(sys.argv)  class mywidget(qt.qwidget):     def __init__(self):         super(mywidget, self).__init__()         self.main = ui_form()         self.main.setupui(self)         # self.main.pushbutton.settext('a'+1)         # prints `typeerror: can't convert 'int' object str implicitly `          self.show()          self.main.pushbutton.clicked.connect(self.show_error)      def show_error(self):         self.main.pushbutton.settext('a'+1)         # print "process finished exit code 1" when clicked on button, , crash.   my_qt_program = mywidget() my_qt_program.show() sys.exit(application.exec_())

test.py(generated qt designer):
