问题
I recently started using qt to build a python GUI. I have two problems I can't quite find the solutions to. the code below is a sample of what I need to build.
1: Check which radio button from a list of radio buttons in a vertical layout has been clicked. In the GUI it only selects one radio button out of all others available in the layout. How do I perceive which has been clicked?
2:I would like to add the clicked value to a JSON object but I believe that is a simple if statement of if this then that. Unless it's more complicated in which case please push me in the right direction.

回答1:
There is a nice way to solve this using Qt Designer, which allows you to group your buttons into a QButtonGroup, and then connect to its buttonClicked signal to get the button that was clicked.
All you need to do is, in Qt Designer, select all the buttons (using Ctrl+click), then right-click one of the buttons and select Assign to button group -> New button group. This will create a new button-group object and automatically add all the buttons to it.
After re-generating your gui module, you can then do somehting like this:
ui.radioButtonGroup.buttonClicked.connect(radioButtonClicked)
def radioButtonClicked(button):
print(button.text())

I think you need something like this (not tested)
# Set Default
self.thi.setChecked(True)
# create a signal
QtCore.QObject.connect(self.that,
QtCore.SIGNAL("toggled(bool)"),
self.radio_clicked)
then create a function
def self.radio_clicked(self):
print 'ive been clicked' # work from here
