Adding grid layout in scroll view.

[Rohan Khedekar]

I wanted to make a scrollable grid layout for my app. But I was unable to do so on my own. Following is a simple piece of code written by me for creating a scrollable grid layout.

import kivymd

from kivy.lang import Builder

from kivymd.app import MDApp

from kivymd.uix.list import OneLineListItem

from kivymd.uix.label import MDLabel

text1='''

Screen:

    ScrollView:

        MDGridLayout:

            id:grid1

            cols:1

            padding:(10,10)

            spacing:(10,10)

            row_default_height:100

'''

class myapp(MDApp):

    def build(self):

        self.t1=Builder.load_string(text1)

        for i in range(50):

            self.t1.ids['grid1'].add_widget(MDLabel(text=str(i+1)))

        return self.t1

myapp().run()

This code creates the grid, but I'm not able to scroll through it. Later I made following changes to my builder string and I got necessary results from the code.

text1='''

Screen:

    ScrollView:

        MDGridLayout:

            id:grid1

            cols:1

            padding:(10,10)

            spacing:(10,10)

            row_default_height:100

            adaptive_height:True

'''

Can you guys tell me what actually is this 'adaptive_height' attribute of 'MDGridLayout' class? How setting it to true allowed me to scroll through my grid layout?

A help from your side will be appreciated.

Thanks and Regards,

Rohan Khedekar.

I don’t use kivymd, but I was curious so I looked at the kivymd docs: https://kivymd.readthedocs.io/en/latest/components/gridlayout/index.html?highlight=adaptive_height#adaptive-height

 

adaptive_height: True

Equivalent

size_hint_y: None

height: self.minimum_height

For the gridlayout to scroll it needs a fixed size, the size_hint needs to be set to None, adaptive_height did that for you.
