Disclaimer: I've read other questions like this already (eg. this one) but didn't find a working solution for me yet (or I just don't understand them :))
When I create a lambda inside a for loop accessing data from the scope of the block I get a pylint warning (cell-var-from-loop) because of the way Python captures work. E.g:
for key, value in data.items():
button = QtGui.QPushButton('show data')
button.clicked.connect(lambda: show_data(value))
table_widget.setCellWidget(1, 1, button)
There are more questions like this but I still don't now how I systematically solve this issue. I tried to provide default values to the lambda like suggested here:
for key, value in data.items():
button = QtGui.QPushButton('show data')
button.clicked.connect(lambda v=value: show_data(v))
table_widget.setCellWidget(1, 1, button)
But when I do it like this weird things happen - while value ought to be a string in my example show_data is being called with a bool.
Am I doing something totally wrong? Should this approach work?
clickedsignal sends acheckedparameter. Use:button.clicked.connect(lambda chk, v=value: show_data(v)).
