[PySide] Signal with custom data

[David Angelo]

Hi folks,

I have a question regarding the usage of signals with custom data
objects and not only "str" or "int".
Is it possible to define signals with custom data objects?
E.g.:

class Data(object):
...

class WidgetSource(QtGui.QWidget):

#signal_node_selected = QtCore.Signal(str)
signal_node_selected = QtCore.Signal(<DATA>)

...

class WidgetTarget(QtGui.QWidget):

def __init__(self):
s = WigdgetSource()
s. signal_node_selected.connect(self.slot_node_selected)

def slot_node_selected(self, data):
#process the data object

Thanks in advance and best regards!

Cheers,
David

Hi David,

Yes is possible to define sinal with python objects, you could use:

signal_node_selected = QtCore.Signal(object)

But this signal will be valid only in pyhon side, sice Qt/C++ does not
know how to handle PyObject.

Hi Renato,

thanks! I only need this signal to be on the python side.
