Widget repeaters in gtk3 using python and glade

Question

I am trying to develop applications for gtk3 using python. I have designed the UI using glade. I want to know if there is any way of using widget arrays, in which each widget of similar type would have the same name, but with a different index. It would help in reducing code to a great extent.

In my application, I have 10 label widgets which display different data, based on an array of data. Now I have to call the gbuilder.get_object() method every time I need to get the desired object. If I were able to use widget arrays, it would really help in reducing the code redundancy.

If you have named the widgets in glade like this:

<widget_name>_1
<widget_name>_2
...
<widget_name>_n

It would be easy to create such a list of widgets in your application like this:

widget_list = [builder.get_object('<widget_name>_{0}'.format(i))
               for i in range(1, n+1)]

To get, for example, item 7, all you need is index the list (note that indexes start with 0):

widget_list[6]

The purpose of {0} is generate the names of the widgets:

>> ['<widget_name>_{0}'.format(i)) for i in range(1, 4)
['<widget_name>_1', '<widget_name>_2', '<widget_name>_3']

For more information about how to use format, please have a look at the format specification mini-language

i got the method. just one question. i have 10 button, which correspond to the same method upon click. i have used a list. there is usage of dictionary for the various signals emitted. how do i add the list of buttons to the dict and should i use the same signal for all the buttons? also, in the method, how am i going to check which button was clicked? the dict is of this format: <code>dic={'on_<widget name>_clicked':method, 'on_<widget name>_clicked':method1} builder.connect_signals(dic) <code>
