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
