I am currently experiencing an issue when trying to use a GridLayout with a ScrollView, in that the top half of the labels in the GridLayout are being cut off by the ScrollView.
For example, here is what it currently looks like:
And, here is the .kv code for this section (it is part of a BottomNavigation):
MDBottomNavigationItem:
id: hmNav
name: 'home'
text: 'Home'
icon: 'home'
GridLayout:
id: hmGrid
cols: 1
rows_minimum: {0: (self.parent.height) * 0.05, 1: (self.parent.height) * 0.2, 2: (self.parent.height) * 0.4, 3: (self.parent.height) * 0.1, 4: (self.parent.height) * 0.1}
row_force_default: True
MDLabel:
id: welcomeLabel
halign: 'center'
font_name: "DMSans"
text: "Hello, " + app.app.getId() + "!"
theme_text_color: "Custom"
font_size: '25sp'
size: self.texture_size
text_color: get_color_from_hex("#08421e")
MDLabel:
id: wLabel2
halign: 'center'
font_name: "DMSans"
text: "Here are your selected ingredients:"
theme_text_color: "Custom"
font_size: '15sp'
size: self.texture_size
text_color: get_color_from_hex("#08421e")
ScrollView:
id: selectedScroll
size: (self.parent.width, self.parent.height)
do_scroll_x: False
do_scroll_y: True
bar_width: 20
GridLayout:
id: selectedGrid
size_hint_y: None
spacing: 60
cols: 2
height: self.minimum_height
MDLabel:
halign: 'center'
text: "TEST1"
font_size: '15sp'
theme_text_color: "Custom"
text_color: get_color_from_hex("#08421e")
size: self.texture_size
MDLabel:
halign: 'center'
text: "TEST2"
font_size: '15sp'
size: self.texture_size
MDLabel:
halign: 'center'
text: "TEST1"
font_size: '15sp'
theme_text_color: "Custom"
text_color: get_color_from_hex("#08421e")

MDLabel:
halign: 'center'
text: "TEST2"
font_size: '15sp'
size: self.texture_size
MDLabel:
halign: 'center'
text: "TEST1"
font_size: '15sp'
theme_text_color: "Custom"
text_color: get_color_from_hex("#08421e")
size: self.texture_size
MDLabel:
halign: 'center'
text: "TEST2"
font_size: '15sp'
size: self.texture_size
MDLabel:
halign: 'center'
text: "TEST 3"
font_size: '15sp'
size: self.texture_size
MDLabel:
halign: 'center'
text: "TEST 4"
font_size: '15sp'
size: self.texture_size
I have used a ScrollView with a BoxLayout successfully, using much of the same configuration as this GridLayout, but I'm unsure of why the top labels are being cut off in this particular instance.
Any help would be greatly appreciated!
Thanks.
When you use height: self.minimum_height in a GridLayout (and others), it calculates the height of the GridLayout based on the height of its children. This means that those children must have explicit height values. You have specified size: self.texture_size for each MDLabel, but that will have no effect if size_hint is left at the default of (1,1). To fix it, just add:
size_hint_y: None
to each of the MDLabels.

I'm building a registration form screen in Kivy. I have some other basic screens as part of the nav bar. However, this is the first one I'm really adding some content to. I have some round text fields that I've just thrown on there to get an idea of spacing, but currently when I reopen the NAV the bar the text field buttons appear in front of it and I want it to be behind.

I need all the elements of my FirsWindow, put them in a recycleview. I'm thinking to do it from RecycleGridLayout instead of GridLayout, but I don't how to really apply it in the code. It's necesary that the GridLayout or RecycleGridLayout have cols:4, I think it's not necessary upload my py.file but I'm not sure. please I need help on this. thanks in advance.

How can I change the mouse pointer to 'hand' when hovering over a button present in a screen along with a different widget in kivy python?
I tried creating two functions in a python file. But it changes the mouse cursor for the entire page. How can I change the cursor for just the button present on the page?

I am currently building a mobile app with Python and KivyMD. On my application I have an MDExpansionPanel which is called in the on_pre_enter method of the ScreenManager. Naturally this will cause that every time I enter to the same page, the widget will be drawn once again.
Is there a way to delete the previous widget before drawing the new one? I've tried several approaches however I have had no success.
The code for a minimal reproducible example is the following:

Thanks a lot in advance.
Here is what I thought was a very simple screen config, and I get three radio buttons. But clicking anywhere on the screen results in the third radio button selecting - you cannot select first or second radio button, and why does it select when the user clicks anywhere on the screen instead of just on the radio button? Clicking anywhere a second time unselects the third item.

The problem is that you have not set any sizes for the CheckBoxes, so each CheckBox gets assigned the default size_hint of (1,1), meaning each one is the same size as their parent FloatLayout. When you click anywhere on that FloatLayout, the last CheckBox added ("Disc 3") gets the event and claims it for itself, and the others never see the event.
Here is a modified version of your kv that sets some sizes:
