How to hide an ActionButton in Kivy?

Question

I am trying to modify the visibility of an ActionButton accordingly to the current screen (using Screen Manager). I could not find a Visible property or something like that

Answer 1

There's a better way to hide widgets than adding or removing them. Simply set the position to include an offscreen coordinate :

# save the old y-coordinate of MyWidget.pos
root.saved_y = MyWidget.y
# Now move the widget offscreen (recall that pos is just an alias for (x, y))
MyWidget.y = 5000

(I've tested this solution; it works.)
