Index radio box and contained buttons

Ibraheem_Khan · July 18, 2014, 4:07am

I have multiple radio boxes containing three buttons as shown below. I want to keep track of clicked radio buttons within radio boxes then do some processing. I am not sure how to index radio box and then clicked radio buttons within that radio box as there are multiple boxes. Any suggestions?

class MyFrame(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, "test", wx.DefaultPosition, wx.Size(900, 600))
        radio1Choices = ['F','G','P']
        # rb_list has 23 records -- basically used to set the distance b/w radio boxes
        for i in rb_list:
            self.radio1 = wx.RadioBox(scroll1, wx.ID_ANY, wx.EmptyString, (550,i), (20,5), radio1Choices, 3, wx.RA_SPECIFY_COLS | wx.NO_BORDER)
            self.radio1.SetSelection( 0 )
            grid_sizer.Add( self.radio1, 0, wx.ALL, 5)

        # Bind the radio box select event to a function
        self.radio1.Bind( wx.EVT_RADIOBOX, self.on_selected )

    def on_selected(self, event):
        if self.radio1.GetStringSelection() == 'F':
            print "F"
        elif self.radio1.GetStringSelection() == 'G':
            print "G"
        else:
            self.radio1.GetStringSelection() == 'P'
            print "P"

    In your handler get the originating radio group from the event

and then decide what to do.

I am not very good at wxpython so a little bit more explanation about possibilities would be really helpful with some form of simple examples. Appreciate it.

Option 1:
In option 2:
Of course this being python you can also use a similar method to
that in 1 to add additional information to each radio group that is
then retrieved and used in a single handler using option 2.
Personally I would say that option 1 results in clearer code for a
relative beginner.

In 2nd option, when I printed:

print event.GetEventObject()

Then I get this:

<wx._controls.RadioBox; proxy of <Swig Object of type ‘wxRadioBox *’ at 0x2c36230> >

Please suggest how do I get index of radiobox within which I clicked radio button, if possible.

Did you check the documentation even once? You use GetSelection to
fetch the currently selected button.

choice = event.GetEventObject().GetSelection()

Tim: I exactly tried that before posting this question. The only missing link is how to index that box first within which I did selection.

print event.GetEventObject().GetSelection()

gives only whether I clicked on radio button 1,2, or 3 but it doesn’t tell about which row/radiobox as there are multiple boxes.

I'm sorry, I misunderstood. So, the issue is NOT finding out which
button was clicked, but rather finding out which BOX that button was in,
right?

What you get back from GetEventObject() is the original RadioBox object
you created. So, if you add your own private store:
self.radio1.my_identity = i

Then in the event handler you can refer to
event.GetEventObject().my_identity

Probably "i" is not the piece of information you want, but I think you
get the idea.

Hmm. This is interesting, instead of giving me identity (sequential number) it gives me its unique position where I placed it in split window.

Yes, of course it does, because that’s what “i” contains in your
original code. That’s exactly why I said this:
You must learn to understand code suggestions before you implement
them.
