I have the following classes in my kivy app, and i would like to call the blink method in my mainApp class. The start pulsing and blink methods enable the MainWindow background to pulse.

Any help will be much appreciated.
The build() method of an App should return a Widget that will become the root of the App. But your build() method returns a ClockEvent (the return from Clock.schedule_once()). Try changing your build() method to:
def build(self):
x = MainWindow()
x.blink()
return x
Since you do not call Builder.load_file(), I assume that your kv file is named main.kv, and therefore will get loaded automatically. If that is true, then you do not need a build() method at all. Instead add an on_start() method to your mainApp class, like this:
def on_start(self):
self.root.ids.main.blink()
imports:

Just access their IDs in a method and then set their text to "" when entering screen, by using on_pre_enter, this method is fired whenever u enter the screen, even if you leave and enter again, it will run
class Login (Screen):
def on_pre_enter(self):
self.ids['benName'].text = ""
self.ids['passwort'].text = ""
I made a program with several buttons and I wish that when I press the button several times, the list of instructions only launches once.
I tried to do it with a global variable but when I want to use the same variable for both screens, I can’t do it.
I know I can do it using two global variables but I would like to use the same one in both screens.
How, when we get to the second screen, u takes the value "True"? Or is there a simpler solution with a decorator?
Here is my code:

This code moves the mauvais() method to the MyScreenManager class, since both versions were identical.
The CLICK_IGNORE_TIME is how long to ignore additional clicks. If it is zero all additional clicks will be ignored
Goal:
Change background color of dynamically created widget with on-press.
Save this state with pickle such that when I open the program back up, the new color change is preserved
Note: You'll see in my code that I haven't made an attempt on saving the button bg color state to a file yet, as I'm still trying to get the on-press event to function.

With button_share.bind (on_press = self.update_buttons_departoverride (self)) you're calling the method, so you're trying to bind on_press with None (self.update_buttons_departoverride return None). If you want to pass arguments, use lambda or functools.partial:
from functools import partial
button_share.bind(on_press=partial(self.update_buttons_departoverride, arg1,...))
However, if you need to pass only the button's reference, it is already passed automatically. You just have to do:
button_share.bind(on_press=self.update_buttons_departoverride)
and:
def update_buttons_departoverride(self, button):

I am trying to implement a custom closable tab header in kivy.
What I did was combine a class:TabbedPanelHeader object with a custom class:CloseButton object. Both of these widgets are inside a class:BoxLayout, side-by-side.
However, once I add this into a class:TabbedPanel object, nothing shows up..
I am not sure how to move forward and would greatly appreciate all the help!
Below is the relevant part of the code.
from kivy.uix.behaviors import ButtonBehavior
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.image import Image
from kivy.graphics import *
from kivy.uix.tabbedpanel import TabbedPanelHeader
class CloseButton(ButtonBehavior, Image):
def __init__(self, **kwargs):
super(CloseButton, self).__init__(**kwargs)
self.source = 'atlas://data/images/defaulttheme/close'
self.size_hint_x = .2
def on_press(self):
self.source = 'atlas://data/images/defaulttheme/checkbox_radio_off'
def on_release(self):
self.source = 'atlas://data/images/defaulttheme/checkbox_radio_off'
## do the actual closing of the tab
class ClosableTabHeader(BoxLayout):
def __init__(self, **kwargs):
super(ClosableTabHeader, self).__init__(**kwargs)
self.size = (100, 30)
self.size_hint = (None, None)
self.canvas.before.add(Color(.25, .25, .25))
self.canvas.before.add(Rectangle(size=(105, 30)))
self.add_widget(TabbedPanelHeader(background_color=(.65, .65, .65, 0), text='testing'))
self.add_widget(CloseButton())
if __name__ == '__main__':
from kivy.app import App
class TestApp(App):
def build(self):
return ClosableTabHeader()
TestApp().run()
Here is some code which comes close to achieve what you are trying to achieve
from kivy.app import App
from kivy.animation import Animation
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.tabbedpanel import TabbedPanel, TabbedPanelHeader
from kivy.factory import Factory
from kivy.lang import Builder
class CloseableHeader(TabbedPanelHeader):
pass
class TestTabApp(App):
def build(self):
return Builder.load_string('''
TabbedPanel:
