This is what it looks like when i run it, which is what i want except the flip button does nothingI have tried many fixes for other people but none worked so I am uploading my work in hopes that someone can help me. If you can please comment but you will likely have to put things in the simplest way possible as I don't have a lot of knowledge.

Change:
btn4.bind(on_push=self.flip)
To:
btn4.bind(on_press=self.flip)
I don't think on_push is a valid action.

What I want to do is take input from kivy.uix.textinput.TextInput() and show it on the screen.
I am new to gui Programming and I think it is an easy task.
import kivy
from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.button import Button
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.textinput import TextInput
class MyWindowApp(App):
def __init__(self):
super(MyWindowApp, self).__init__()
self.lbl = Label(text='Read Me!')
self.inp = TextInput(multiline=False,
size_hint =(1, 0.05),
pos_hint = {"x":0, "y":0.05})
def build(self):
self.inp.bind(on_text_validate=self.on_enter)
#self.bt1.bind(on_press=self.clk)
layout = FloatLayout()
layout.orientation = 'vertical'
layout.add_widget(self.lbl)
layout.add_widget(self.inp)
return layout
def on_enter(self,value):
print(value)
def clk(self, obj):
print ('input')
x = input()
self.lbl.text = x
window = MyWindowApp()
window.run()
when i run the code, I get the regular output output.
when I type say "hello world" in the textbox, this is the output:
<kivy.uix.textinput.TextInput object at 0x03F5AE30>
I do not get what I typed.
please suggest what should I do
Modify the following ...
def on_enter(self, value):
print(value.text)
I am newbies to programming, just picking up python. I have a very simple program which is showing a popup message, and it seems OK:
from kivy.app import App
from kivy.uix.button import Button
from kivy.uix.label import Label
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.popup import Popup
class t6App(App):
def build(self):
lb = Label(text="Welcome Here",size_hint=(1,0.8),pos_hint={'left':1,'top':1})
bt = Button(text="Press Me", size_hint=(1,0.1),pos_hint={'left':1,'x':0})
fl = FloatLayout()
fl.add_widget(lb)
fl.add_widget(bt)
cp = Popup(title='Guys', content=fl)
return cp
t6App().run()
Then I wanted to modify it, and add more things to it, the popup didn't show then: (2 programs always the same)
from kivy.app import App
from kivy.uix.button import Button
from kivy.uix.label import Label
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.popup import Popup
class CustPop(Popup):
def build(self):
lb = Label(text="Welcome Here",size_hint=(1,0.8),pos_hint={'left':1,'top':1})
bt = Button(text="Press Me", size_hint=(1,0.1),pos_hint={'left':1,'x':0})
fl = FloatLayout()
fl.add_widget(lb)
fl.add_widget(bt)
cp = Popup(title='Guys', content=fl)
return cp
class t6App(App):
def build(self):
cp1 = CustPop()
return cp1
t6App().run()
The codes do run, but it seems like the layout /button /label in CustPop() can't be accessed (became a blank popup). My question is why and how to make it work?
Thx guys. I am appreciated.
You have defined a build() method in your CustPop, but unlike the App class, that build() method is not automatically called. You should put that code (with a couple minor changes) in the __init__() method.
class CustPop(Popup):
def __init__(self, **kwargs):
super(CustPop, self).__init__(**kwargs)
lb = Label(text="Welcome Here", size_hint=(1, 0.8), pos_hint={'left': 1, 'top': 1})
bt = Button(text="Press Me", size_hint=(1, 0.1), pos_hint={'left': 1, 'x': 0})
fl = FloatLayout()
fl.add_widget(lb)
fl.add_widget(bt)
# cp = Popup(title='Guys', content=fl)
self.title = 'Guys'
self.content = fl
I am trying to make tambola coin picker with Python and Kivy and I am new to kivy.
Here, I created gridlayout buttons from 1 to 90. I want to change the color of particular button in gridlayout when its number is picked. I am facing issues to update gridlayout with new colored button. Here I am attaching my code. screenshot
#!/usr/bin/python
from kivy.app import App
from kivy.uix.button import Button
from kivy.uix.label import Label
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.gridlayout import GridLayout
from kivy.graphics import Color
import random
coins = random.sample(range(1,91), 90)
#print(coins)
picked_coins=[]
current_coin=0
#print(picked_coins)
class Housie(FloatLayout):
def __init__(self,**kwargs):
super(Housie,self).__init__(**kwargs)
self.title = Label(text="Housie Coin Picker",font_size = 50,size_hint=(1, .55),pos_hint={'x':0, 'y':.45})
self.main_label = Label(text = "Click PICK NUMBER", size_hint=(1, .60),pos_hint={'x':0, 'y':.35})
self.picked_ones = Label(text = "picked_coins", size_hint=(1, .40),pos_hint={'x':0, 'y':.40})
self.help_button = Button(text = "PICK NUMBER", size_hint=(.3, .1),pos_hint={'x':.65, 'y':.1},on_press = self.update)
self.add_widget(self.title)
self.add_widget(self.main_label)
self.add_widget(self.picked_ones)
self.add_widget(self.help_button)
self.add_widget(self.userinterface())
def userinterface(self):
self.layout = GridLayout(cols = 10,size_hint=(.50, .50))
for i in range(1,91):
self.layout.add_widget(Button(background_color=(1,0,0,1),text =str(i)))
return self.layout
def update(self,event):
for coin in coins:
if coin not in picked_coins:
current_coin=coin
picked_coins.append(coin)
self.main_label.text = str(coin)
for i in self.layout.children:
if i.text == str(coin):
#What to do Here?
break
self.picked_ones.text = "Picked coins = {}".format(" ".join(str(sorted(picked_coins))))
class app1(App):
def build(self):
return Housie()
if __name__=="__main__":
app1().run()
You can bind a method to each Button like this:
def userinterface(self):
self.layout = GridLayout(cols = 10,size_hint=(.50, .50))
for i in range(1,91):
self.layout.add_widget(Button(background_color=(1,0,0,1),text=str(i), on_release=self.butt_pressed))
return self.layout
def butt_pressed(self, button):
button.background_normal = ''
button.background_color = (1,0,0,1)
Th butt_pressed() method changes the background color of the pessed Button.
I'm using kivy and I am trying to make a program to help me remember the super saiyans transformations. I wanted the buttons to be pictures instead of words. So here is the code I used to make the button a picture:
self.Goku = Button(background_normal = '106-1060675_goku-base-form-png-clipart (1).png')
self.Goku.bind(on_press = self.SonGoku)
self.add_widget(self.Goku)
When I runned the code to see what it looks like, I saw that one of the picture was to big and one to small. So I tried to resize the picture by adding size = ("10, 10") but it didn't work. I tried the same thing with size_hint, but it had the same result. Nothing moved. I looked at some documentations about the button and adding pictures to kivy but it didn't help much. Here's the entire code:
import kivy
from kivy.app import App
from kivy.graphics import *
from kivy.uix.label import Label
from kivy.uix.image import Image
from kivy.uix.button import Button
from kivy.uix.widget import Widget
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.gridlayout import GridLayout
class main(GridLayout):
def __init__(self, **kwargs):
super().__init__(**kwargs)
self.cols = 4
self.Goku = Button(background_normal = '106-1060675_goku-base-form-png-clipart (1).png', size_hint = (1, 0.5))
self.Goku.bind(on_press = self.SonGoku)
self.add_widget(self.Goku)
self.Vegeta = Button(background_normal = 'vegeta-png-clip-art.png', size_hint = (1, 1))
self.Vegeta.bind(on_press = self.PrinceVegeta)
self.add_widget(self.Vegeta)
def SonGoku(self, instance):
self.cols = 1
self.remove_widget(self.Goku)
self.remove_widget(self.Vegeta)
self.NormalGoku = Button(text = "Base form")
self.add_widget(self.NormalGoku)
self.SSJGoku = Button(text = "Super saiyan")
self.add_widget(self.SSJGoku)
self.SSJ2Goku = Button(text = "Super saiyan 2")
self.add_widget(self.SSJ2Goku)
def PrinceVegeta(self, instance):
self.cols = 1
self.remove_widget(self.Goku)
self.remove_widget(self.Vegeta)
self.NormalVegeta = Button(text = "Base form")
self.add_widget(self.NormalVegeta)
self.SSJVegeta = Button(text = "Super saiyan")
self.add_widget(self.SSJVegeta)
self.SSJ2Vegeta = Button(text = "Super saiyan 2")
self.add_widget(self.SSJ2Vegeta)
class Saiyan(App):
def build(self):
return main()
if __name__ == "__main__":
Saiyan().run()
Help would be appreciated. Feel free to ask any question. Thanks in advance.
One way of doing it would be to draw the image on the buttons canvas. the attributes "allow_stretch" and "keep_ratio" are used to fill the entire button size.
from kivy.uix.image import Image
Then:
self.Goku = Button(size_hint=(None, None), size=(120,120))
with self.Goku.canvas:
Image(source='vegeta-png-clip-art.png', size=self.Goku.size, pos=self.Goku.pos, allow_stretch=True, keep_ratio=False)
self.add_widget(self.Goku)
In case you are not setting the size explicitly for the button you need to bind the size attribute to a method in order to resize the image.
example:
class main(GridLayout):
def __init__(self, **kwargs):
super().__init__(**kwargs)
self.cols = 4
self.Goku = Button()
with self.Goku.canvas:
self.Goku_img = Image(source='vegeta-png-clip-art.png', size=self.Goku.size, pos=self.Goku.pos, allow_stretch=True, keep_ratio=False)
self.Goku.bind(size=self.adjust_size)
self.add_widget(self.Goku)
...
def adjust_size(self, instance, value):
self.Goku_img.size = value
I hope this is a suitable approach for you.
So i'm learning Kivy for a school project and i got an error when testing out Buttons. Here is my Code:
from kivy.app import App
from kivy.uix.gridlayout import GridLayout
from kivy.uix.label import Label
from kivy.uix.textinput import TextInput
from kivy.clock import Clock
from kivy.uix.button import Button
class übung(GridLayout):
def lol(instance):
label.disabled = False
def __init__(self):
super(übung, self).__init__
self.cols = 2
self.label = Label ("Ehrm ... lol")
label.disabled = True
self.btn1 = Button(text="Hello world 1")
self.btn1.bind(on_press=lol)
self.btn2 = Button(text="Hello world 2")
self.btn2.bind(on_press=lol)
class App(App):
def build(self):
return übung()
if __name__ == "__main__":
App().run()
The Error I'm getting is in the title(init takes 1 postitional argument but 2 were given). It is supposed to be two buttons and if you press one it say ehrm ... lol. As i said, it is just for testing purposes.
Thanks in Advance,
me
You have several errors. The error you display is because you have to pass the argument (text) to the Label constructor by name:
self.label = Label (text="Ehrm ... lol")
Your code should look something like this:
from kivy.app import App
from kivy.uix.gridlayout import GridLayout
from kivy.uix.label import Label
from kivy.uix.button import Button
class übung(GridLayout):
def __init__(self, **kwargs):
super(übung, self).__init__(**kwargs)
self.cols = 2
self.label = Label(text = "Ehrm ... lol")
self.label.disabled = True
self.btn1 = Button(text="Hello world 1")
self.btn1.bind(on_press=self.lol)
self.btn2 = Button(text="Hello world 2")
self.btn2.bind(on_press=self.lol)
self.add_widget(self.label)
self.add_widget(self.btn1)
self.add_widget(self.btn2)
def lol(self, event):
self.label.disabled = False
class App(App):
def build(self):
return übung()
if __name__ == "__main__":
App().run()
