Remove space on invisible widgets

[Javier Uribe]

I'd like to make some widgets invisible so i put them with opacity to 0. The problem is that they are invisible but they take space. So I'm implementing a way to remove the space they take.

As the widgets display vertically I thought that I just had to set the size_hint_y to 0 so theoretically they wouldn't take any percentage of the parent's height but it is not working.

To sum up, I have a vertical layout with widgets, if you set the opacity to 0 they are invisible but taking space and I want to remove it, so the next widget would take its place like it wouldn't exist.

So any ideas?

The layouts would be like this:

GridLayout
    cols:1    

    BoxLayout
    BoxLayout
    ...
    BoxLayout

   

So basically we have 1 column and a lot of rows. I want the remove the space the horizontal boxlayouts take.

Thank you very much.

Why not just rebuild the entire layout?

I've just solved it! It turns out that if we have widgets inside a boxlayout (which is inside a gridlayout), and we want to change their percentage of space the way to do it is by changing the boxlayout's size_hint, not the widgets's. So If I set the size_hint_y to 0 on the boxlayouts it works.
