        super().__init__()

        self.points = Points(np.random.normal(size=(1000, 2)), size=0.05)
        self.button = Button(pg.Rect(50, 50, 120, 40), "Click me")

        if self.button.is_clicked:
            print('clicked')


viewer = SimpleViewer()
viewer.run()

Features

• Rendering of different drawable objects (Lines, Points, Images, Texts)
  • Renders 100_000 points fluently, and can also handle 1_000_000 points and above (with some lag) (Rendering Lines is slow)
• UI elements (Buttons, Labels, EditField, TextField)
  • EditField and TextField support many keyboard shortcuts, selection, copy/paste, ...
• Fast scrolling and zooming
