Getting ready

We will use this example of a file, e8.kv, where two widgets are defined:

<MyWidget1>:
    Button: 
        on_press: self.text(txt_inpt.text) 
    TextInput: 
        id: txt_inpt 
<MyWidget2>: 
    Button: 
        on_press: self.text(txt_inpt.text) 
    TextInput: 
        id: txt_inpt

We must note that they are very similar, and actually just the name of the widget is different between them.

How to do it…

The following steps provide a way to join the two widgets:

How it works…

In this case, by separating the class names with a comma, all the classes listed in the declaration will have the same KV properties and you could join any number of similar widgets.

There's more…

In the Python code, the widgets could do different tasks, as in the next portion of code:

class MyWidget1(Widget):
    def text(self, val):
        print('text input text is: {txt}'.format(txt=val)) 
class MyWidget2(Widget): 
    writing = StringProperty('') 
    def text(self, val): self.writing = val 

Similarly, you can join the widgets in the Kv language.
