I have tried many posts here in relation to my problem but nothing works for me. I am sure that i am not good enough to understand them.
I want to basically send a datatable to the popup window. I made the same program with ttk.treeview. this ttk.treeview showed me a good table. but now i want to upgrade it with kivy. hence i chose datatable. i could not find any other option to show a nice looking data table like ttk.treeview. Do you have any suggestion besides datatable?
When you run this python file, you will see popup screen. you click "Dex", then it opens a popup window. You put any data there then Click "Calculate", then i want to show the result of the calculation of those inputs into the bottom button space of this window.
I put a dummy datatable in the calculate(self) function.
Would you help me with this? My problem line is python file line 77.
Tons of thanks in advance.

In order to get your code to run, I needed to change:
class AwesomeApp(App):
to
class AwesomeApp(MDApp):
Then, in your kv file, change the last part of the <Dex> rule from
BoxLayout:
canvas:
Color:
rgba: [1,1,.1,.6]
Rectangle:
pos:self.pos
size:self.size
Button:
id: data_layout
text: "i want to show data here when Calculate clicked"
pos_hint: {"bottom": .2}
size_hint: .8,.4
to
BoxLayout:
id: data_layout
canvas:
Color:
rgba: [1,1,.1,.6]
Rectangle:
pos:self.pos
size:self.size
And then a small change to the calculate() method, by changing:
self.root.ids.dexme.ids.data_layout.add_widget(self.data_tables)
to:
self.ids.data_layout.add_widget(self.data_tables)
Since the calculate() method is in the Dex class, you don't need to use ids to get to the Dex instance, just use self instead.
