Hi there,
I'm facing a problem that I never noticed before in python / qt : when I
try to raise an error from a function triggered by a signal, I can't get
the red message in maya. The error is raised in the script editor, but if
the SE is closed, no way to know that an error occured.
To see what I mean, you can run the piece of code at the end of my post.
>From what I understood, it comes from the mechanism of signals / slots
itself, like if the function triggered by a signal was 'local' only. If I
call the same method manually (i.e. NOT with the signal), it works.
I tried with both pyqt4 and pyside, same result.
I have a couple of workarounds (I can use the api to raise my error
instead, or I can use logging), but the truth is that I really like the
built-in errors in python, and I'd love to be able to stick to this
workflow if possible.
If anyone has a solution for that, I'd be really happy to know it !
Many thanks
from PySide.QtGui import *
from PySide.QtCore import *
class Xxx(QWidget):
def __init__(self, parent=None):
super(Xxx, self).__init__(parent)
self.ui()
def ui(self):
btn = QPushButton('Raise error')
btn.clicked.connect(self.raiseError)
mainLayout = QHBoxLayout()
mainLayout.addWidget(btn)
self.setLayout(mainLayout)
def raiseError(self):
raise NameError
a = Xxx()
a.show()
