How to Give Shapes Background Images with Python and Kivy!
If you are a developer looking to create graphical user interfaces with Python, you may have come across Kivy. This powerful open-source library allows you to create cross-platform applications with ease. However, you may be wondering how to give shapes background images in Kivy.
Here’s how you can achieve this with Python and Kivy:
- First, make sure you have Python and Kivy installed on your system.
- Create a new Kivy project or open an existing one.
- In your Kivy project, create a new class for the shape you want to give a background image. For example, if you want to create a rectangle with a background image, you can create a RectangleImage class.
- Within the class, use the canvas object to draw the shape. Then, use the Rectangle object to define the background image. You can do this by specifying the source attribute with the file path to the image.
- Here is an example of how the code may look:
from kivy.app import App
from kivy.uix.widget import Widget
from kivy.uix.image import Image
from kivy.lang import Builder
class RectangleImage(Widget):
def __init__(self, **kwargs):
super(RectangleImage, self).__init__(**kwargs)
with self.canvas:
self.rect = Rectangle(source='path_to_image.png', pos=self.pos, size=self.size)
def on_size(self, *args):
self.rect.size = self.size
self.rect.pos = self.pos
class MyApp(App):
def build(self):
return RectangleImage()
if __name__ == '__main__':
MyApp().run()
Replace path_to_image.png with the actual file path to your desired background image.
Once you have implemented the above code, you should be able to see the shape with the background image displayed in your Kivy application.
By following these steps, you can easily give shapes background images in Python and Kivy. This can be a useful technique for enhancing the visual appeal of your applications and creating more engaging user experiences.
Hi, thank you for the video.
One thing though. When trying this on my raspberry pi zero with touchscreen, it works perfectly… until I try to actually do something in the event like switch a smart bulb. That's when I notice that the event is systematically called twice when I touch the screen. Any idea why ?
I don't mind doing GUI. Will check the upcoming stuff for sure. Cheers!
