QUESTION
I was trying to use display seaborn plot in kivy. Sometime the figure cann't fit into the MDBoxLayout. I checked the sizes of FigureCanvasKivyAgg and MDBoxLayout. But in the MDBoxLayout, the figure is not cropped. Is there a way to enable the plot to fit the MDBoxLayout automatically? Thanks in advance.

The code below is a demo I wrote. What I want to accomplish is that I have to click the button in the first tab before using other tabs. If the button is not clicked and I try to go to other tabs, a message will be shown and I'll be lead to the first tab. The problem is that the message will be shown, but I have to click one more time to go back to the first tab. Any idea how to fix it? Thanks in advance!

I am making a desktop application using kivy & kivymd and when creating the settings screen for the app I used two MDRectangleFlatButon and MDRaisedButtons but to make them scalable, I gave both of them a size_hint_x of .5 for each to take up half of the screen. However, as soon as the program starts I get this warning from kivy:

QUESTION
Iam trying to learn how to program with KivyMD. After doing some research and watching some tutorials iam putting a GUI together with the trail-and-error approach.
At the moment iam trying to change the colors of the Tab text and icons. After hours of online searching iam still not able to change them. The text_color_normal:and text_color_active: in the .kv file simply
seems to have no effect on them. I have the feeling iam doing something fundamentally wrong here. Can somebody give me some tips how to proceed? Main.py and .KV file are below.
Thanks in advance!

Maybe try reinstall KivyMD.
QUESTION
Python 3.6.4 - Kivy 1.11.1 - KivyMD 0.104.1
I'm fairly new with Kivy and kivyMD, and even more with threading and shared resources.
Today, I fill in the 3 MDGridlayouts (sbgridfamily, sbgridgender, sbgridspecies) sequentially with SmartTileWithLabels. It works fine, however the loading time is quite long (~5 sec.).
To optimize this loading, I tried
to split the loads in different threads, without using a lock or a semaphore, some cells end up empty.
to remove the MDGridlayouts from the structure and create them on the fly in one thread, then I get an assertion error as soon as I add the first tile to a MDGridlayout.

My problem was the creation and loading time of about 300 thumbnails with on-the-fly resizing of the images, if they were missing from a cache.
In order to optimize, without using threads, I will redirect my next development towards loading galleries at least one page for each tab (50 thumbnails) using Clock.schedule_once when starting the application, then page by page on demand, using the on_scroll_start and on_scroll_move scrollview events.
After a quick try, with this approach, the screen appears in less than a second the first time, then it's immediate.
QUESTION
Since two days I have tried to solve this problem. I try almost everything. I checked my ids 10 times whether or not they are string. They are not!! I put clock.schedule_one method for delaying initializations but program does not define ids in kv file. Here is the code;

QUESTION
Iam trying to learn coding with Python and iam making an application that tracks session times from users using KivyMD. At the moment iam trying to display the total amount of time by fetching json data trough an api call from my database. I wrote a function to fetch and process the json data to calculate the total time. The function must fire automatically to show the data (variable:total_minutes) in the MDLabel time_label when the Mijn sessie Tab loads. This is where iam getting very confused.
I found the on_pre_enter function in Kivy which fires the function when the screen loads but it only works in the Screen Class and not in the Tabs Class. I have no idea how i can use the python variable in the Tabs class if i do the python logic in the Screen class. I have tried many things with Objectproperty and Stringproperty but none where succesfull. I think iam missing something bigger here.
I will post the code to make things more clearly when you will see the application for yourself. For safety reasons i replaced the api request function with a small function which produces the same outcome (float).
Many thanks in advance!
