nevu-ui 0.6.3

A powerful GUI framework for Pygame that allows you to create menus

Brief Description

Nevu UI is a library for the declarative creation of user interfaces in Pygame. The project aims to provide developers with a set of ready-made, stylable, and extensible components for the rapid creation of modern and responsive interfaces in games and multimedia applications.

The main goal of Nevu UI: to make creating interfaces in python even easier and faster

Key features include:

• Layout system: Convenient arrangement of elements, for example, using grids (Grid) and scrollable containers (Scrollable).
• Set of widgets: Ready-to-use elements such as buttons, input fields, and labels.
• Flexible styling: The ability to customize the appearance through a style system that supports colors, gradients, and borders.
• Animations: Built-in support for animations to create dynamic and lively interfaces.
• Declarativeness: Support for declarative interface creation

Style

Style - a universal storage of parameters for customizing the appearance

Editable parameters:

• Gradient
• ColorTheme - Analogous to MaterialDesign
• Font name/size
• Border Width/Radius
• Text Align X/Y
• Transparency

Main Features

Nevu UI allows you to describe an interface with a clear structure

Examples of declarativeness:

• Declarative approach: Describe your interface just as you see it.

  # Specify content directly when creating the layout
  grid = ui.Grid(content={(1,1): ui.Button(...)})
  

• Adaptive size system (SizeRules): Forget about pixels. Use relative values that adjust to the size of the window or parent element.

  • vh / vw: Percentage of the window's height/width.
  • fill: Percentage of the parent layout's size.

• Powerful style system: Customize every aspect of the appearance using the universal Style object.

  • Themes: Ready-made color themes (synthwave_dark_color_theme).
  • Gradients: Linear and radial.
  • And much more: Fonts, borders, rounding, transparency.

• Built-in animations: Bring your interface to life with ready-made animations for appearance, movement, etc.

Basic Grid

Declarative Approach

import nevu_ui as ui #Import Nevu UI
import pygame

pygame.init()

class MyGame(ui.Manager): #Create the base of our application
    def __init__(self):
        window = ui.Window((400, 300), title = "My Game") #Create a window
        super().__init__(window) #initialize the manager
        self.menu = ui.Menu(self.window, [100*ui.vw, 100*ui.vh], #Create a menu
                            layout= ui.Grid([100*ui.vw, 100*ui.vh], row=3, column=3, #Create a grid layout
                                            content = {
                                                (2, 2): ui.Button(lambda: print("You clicked!"), "Button", [50*ui.fill,33*ui.fill]) #Create a button
                                            }))
    def draw_loop(self):
        self.menu.draw() #draw the menu
    def update_loop(self, events):
        self.menu.update() #update the menu

game = MyGame()
game.run() #Run the finished application

Imperative Approach

import nevu_ui as ui #Import Nevu UI
import pygame

pygame.init()

window = ui.Window((400, 300), title = "My Game") #Create a window

menu = ui.Menu(window, [100*ui.vw, 100*ui.vh]) #Create a menu

layout = ui.Grid([100*ui.vw, 100*ui.vh], row=3, column=3) #Create a grid layout
layout.add_item(ui.Button(lambda: print("You clicked!"), "Button", [50*ui.fill,33*ui.fill]), x = 2, y = 2) #Create a button

menu.layout = layout #Set the menu layout

while True: #Main loop
    events = pygame.event.get() #Get events
    window.update(events) #Update the window
    menu.update() #Update the menu
    menu.draw() #Draw the menu
    pygame.display.update() #Update the screen
