detecting child widgets collision

[George Munyalo]

Is there a way to detect the collision of two child widgets? It seems to me that the collide_widget method only detects collision between the current widget(i.e the current class which is also the parent class/widget) and another specified widget.
Thanks

Best would be using the collide_widget method from one of your child widgets.

Checking the implementation of the collide_widget method within kivy/uix/widget.py - it is actually very simple to roll your own method with two widget parameters:

```

        if self.right < wid.x:

            return False

        if self.x > wid.right:

            return False

        if self.top < wid.y:

            return False

        if self.y > wid.top:

            return False

        return True

```

Thanks. I was able to achieve this by accessing the child widget instances (self.child1.collide_widget(self.child2))
