In the above code, we have imported partial function from the functools so that we can use the bind() function.Ī KivyButton() class is created with two custom methods. Mybtn.bind(on_press=partial(self.update, mybtn)) Mybtn.bind(on_press=partial(self.disable, mybtn)) Mybtn = Button(text="Click me to disable") mybtn.disabled = TrueĬonsider the following code to disable a button after we press it: from import Button To disable a button, you have to set the disabled property to True. When you run the program, it will show the button like this: Return Button(text="Welcome to LikeGeeks!", background_color=(155,0,51,53)) The code demonstrated below: from kivy.app import App You can change the color by specifying the background_color property in the format (r, g, b, a). The default color of a Kivy button is grey. The button fills the window, don’t worry, we will resize it later. The entire output screen will be as follows: Return Button(text="Welcome to LikeGeeks!") To create a button, import button instead of a label as follows: from kivy.app import App

In this section, you will learn how to create a button, change the color of a button, enable/disable, how to add an image on the button, and how to change its size & position. The result of this code will be like this:Ĭongratulations! Your first Kivy app runs successfully. The entire python file looks like the following: from kivy.app import App You can either create an object of the class or just write the following statement: FirstKivy().run() In the code above, we have returned a label with the text “Hello Kivy”. Then to build the application, we have to return a widget on the build() function. In the above snippet, a class is inherited from the App class. Now is the time to write our main program. Now importing label from : from import Label To create a Kivy interface, we first need to import the Kivy app module in our program using the following statement: from kivy.app import App In this section, you will learn how to create and run a Kivy program and how to build a basic interface in Kivy.
