Hi together,
I've a problem using the QCheckBox.stateChanged Signal within a
QSignalMapper.
The stateChanged Signal is emitted with an integer argument but the
QSignalMappers
map() Slot only accepts a call without an argument ... so I get the
following error.
Error calling slot "map"
TypeError: 'PySide.QtCore.QSignalMapper.map' called with wrong
argument types:
PySide.QtCore.QSignalMapper.map(int)
Supported signatures:
PySide.QtCore.QSignalMapper.map()
PySide.QtCore.QSignalMapper.map(PySide.QtCore.QObject)
Is there some kind of a solution?
Here is a snipplet of my code:
class Picsim(QtGui.QMainWindow, Ui_MainWindow):
cb_changed = QtCore.Signal(int)
def __init__(self, parent=None):
super(Picsim, self).__init__(parent)
self._checkbox_mapper = QtCore.QSignalMapper(self)
self._connect_checkboxes()
def _connect_checkboxes(self):
"""Connects all the CheckBoxes to _set_value_cb_mem"""
for bank in xrange(0,2):
for row in xrange(0,12):
for col in xrange(0,8):
bank_intern = bank * 8
if row == 10:
row_intern = "A"
elif row == 11:
row_intern = "B"
else :
row_intern = row
cbname = "CB_" + str(bank_intern) +
str(row_intern) + str(col)
cb = getattr(self, cbname)
self._checkbox_mapper.setMapping(cb, cbname)
cb.stateChanged.connect(self._checkbox_mapper.map)
self._checkbox_mapper.mapped.connect(self.cb_changed)
self.cb_changed.connect(self._set_memvalue)
@QtCore.Slot(str)
def _set_memvalue(self, name):
"""Sets the value of a given CheckBox to its memory
location"""
print name
