I am trying to use two sliders in layout. The code is given below. The problem is only the second slider responds to the mouse actions. The first slider (and also the button) does not respond at all to the mouse actions. How to make both sliders responsive?
Thanks in advance
from kivy.app import App
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.slider import Slider
from kivy.uix.button import Button
def Exit(instance):
print('Exit the screen')
App.get_running_app().stop()
def MainScreen():
flt = FloatLayout()
button = Button(text='Hello Kivy World')
button.size = (200, 100)
button.size_hint = (None, None)
button.pos_hint = {'center_x': .5, 'center_y': .2}
button.bind(on_press=Exit)
flt.add_widget(button)
slid1 = Slider()
slid1.id = 'Slider 01'
slid1.size_hint_x = .75
slid1.pos_hint = {'x': .125, 'center_y': .5}
slid1.value_track = True
slid1.value_track_color = [0, 1, 0, 1]
slid1.sensitivity = 'handle'
flt.add_widget(slid1)
slid2 = Slider()
slid2.id = 'Slider 02'
slid2.size_hint_x = .75
slid2.pos_hint = {'x': .125, 'center_y': .75}
slid2.value_track = True
slid2.value_track_color = [1, 0, 0, 1]
slid2.sensitivity = 'handle'
flt.add_widget(slid2)
return flt
class MainApp(App):
def build(self):
return MainScreen()
if __name__ == "__main__":
app = MainApp()
app.run()
If you change your floatlayout to a boxlayout it works.
flt = BoxLayout(orientation='vertical')

My program parses the site at the click of a button and displays the text of the book on the user's screen. But since I'm a beginner, I can't find the ScrollView argument that would repaint it in the color I want. Maybe I'm doing something wrong, I would be glad if someone could tell me how to display the text on the screen ScrollView, which is not black!

You need your Label to adjust according to its text. The easiest way to do that is by using the kivy language. Here is one way to do it:
Add a new class MyLabel:
class MyLabel(Label):
pass
Use the new class in your python:
sc.add_widget(MyLabel(text=f'{data}',color = (1,1,1,1)))
Add use the kivy language to define the new class:
class MyApp(App):
def build(self):
Builder.load_string('''
<MyLabel>:
size_hint: 1, None
text_size: self.width, None
height: self.texture_size[1]
''')
return Box()
I have a program that parses text from a site and outputs it. But the problem is that when I put this text in ScrollView then at 4 pages of the book it is displayed, but at 57 pages it simply is not. Only if I change the value of font_size to 1, only then the entire text of the book is displayed, but obviously this is not what I need. How to solve this problem?

I wanted to remove the 'bl' widget by clicking the 'horny mode' button, but it is not initially on the screen. How can I make the widget be removing by clicking on the button?

Can you help me make so that when you click on any button, the widget with the buttons removed?
First, save a reference to the widget that you want to remove:
def build(self):
self.bl = BoxLayout(orientation='horizontal', padding=[50, 100, 50, 150], spacing=5)
self.bl.add_widget(Button(text='1', on_press=self.first, font_size=20, size_hint=(.3, .1)))
self.bl.add_widget(Button(text='2', on_press=self.second, font_size=20, size_hint=(.3, .1)))
# self.bl.add_widget( Button(text = 'Wallpaper mode', on_press = self.wallpaper, font_size = 20, size_hint = (.3, .1)))
wid = FloatLayout()
wid.add_widget(ScraperApp().PhotGif())
wid.add_widget(self.bl)
return wid
Then modify the first() method to remove it:
def first(self, instance):
print('Horny mode')
instance.text = 'кнопка нажата'
self.root.remove_widget(self.bl)
self.stop()
Note that the code:
ScraperApp().build().remove_widget(bl)
creates a new instance of the ScaperApp and tried to remove bl from that instance. Aside from other problems, nothing you do to that new instance will affect the instance that is currntly running.
I am trying to update a label field dynamically from the contents of a TextInput in a ModalView. The idea is that in the TextInput one enters plain text including markup formatting and you will see the results directly in the Label field with markup = True.
Unfortunately I do not know how to access the Label item in the ModalView. Who can help? See the example code below.
Thanks in advance.

You have to make a binding between the TextIntput text and the Label, for this we can use a lambda function and setattr.
class Test(BoxLayout):
minput_text = StringProperty('Welcome')
txtresult = ObjectProperty()
def showedit(self):
mview = ModalView(id='mviewid', size_hint=(0.4, 0.6), auto_dismiss=False, background='./images/noimage.png')
mblt = BoxLayout(orientation='vertical', padding=(24))
minp = TextInput(id='inptxt', text='', hint_text='Start typing text with markup here', size_hint=(1,0.5),multiline=True)
minp.bind(text=self.on_inptext)
mtxt = Label(id='txtresult',text='displays formatted text', color=(0.3,0.3,0.3), size_hint=(1,0.5),markup=True)
mcnf = Button(text='OK', size=(144,48), size_hint=(None,None))
mcnf.bind(on_press=mview.dismiss)
mblt.add_widget(minp)
mblt.add_widget(mtxt)
mblt.add_widget(mcnf)
mview.add_widget(mblt)
mview.bind(on_dismiss=self.print_text)
# binding between TextInput text and Label text
minp.bind(text=lambda instance, value: setattr(mtxt, 'text',value))

I am a newbie in kivy. I made a tic tac toe game, but when one of the player wins I want the game to restart so, the players can play it again. How can I make this in kivy or should I reset the buttons and lists that the game based on? I have tried many things like

Your TicTacToeApp should have the build method that returns a widget.
I will give you an example, where it is a quiz app, when the correct button is pressed (or released, in kivy lang), the app will update its quiz.
import random
from kivy.app import App
from kivy.uix.button import Button
from kivy.uix.gridlayout import GridLayout
from kivy.uix.label import Label
Q_sets = ["1+1=...","1+6=...","77-43=..."];
Opt_sets = [["2", "23"], ["4","7"], ["34","66"]];
Ans_sets = ["2","7", "34"];
class Option(Button):
def __init__(self, label):
super().__init__(self);
self.text = label;
def on_release(self):
super().on_release(self);
if self.text == self.parent.answer:
self.parent.parent.clear_widgets();
index = int(random.uniform(0, 3));
New = Quiz(Q_sets[index], Opt_sets[index][0], Opt_sets[index][1], Ans_sets[index]);
self.parent.parent.add_widget(New);
class Quiz(GridLayout):
def __init__(self, question, opt1, opt2, correct):
super().__init__(self, rows=3, cols=1);
self.question_label = Label(text=question);
self.opt1_button = Option(label=opt1);
self.opt2_button = Option(label=opt2);
self.answer=correct;
self.add_widget(self.question_label);
self.add_widget(self.opt1_button);
self.add_widget(self.opt2_button);
class QuizzesApp(App):
def build(self):
Container = GridLayout();
Container.add_widget(Quiz(Q_sets[0], Opt_sets[0][0], Opt_sets[0][1], Ans_sets[0]));

You may study this, and then improvise for your own case. Is this okay?
