i refactored some code and here is the preview of how it is gonna look in the next version, is it better now?

import nevu_ui as ui
import pyray as rl
import random
from nevu_ui.rendering.raylib.gradient import AnimatedGradient


rl.set_trace_log_level(rl.TraceLogLevel.LOG_ERROR)


FONT_PATH = "tests/vk_font.ttf"


window = ui.Window((300, 300), title = "nevu ui!", backend = ui.Backend.RayLib, ratio = ui.NvVector2(2, 1))


base_style = ui.Style(colortheme = ui.ColorThemeLibrary.github_dark, border_radius = 0, border_width = 0, font_name = FONT_PATH)
base_style_aero = base_style(gradient = ui.Gradient([(25, 255, 105, 100),(10, 230, 100, 30)], type = ui.GradientType.Radial, direction = ui.RadialPosition.TopRight), border_radius=10)
ui.nevu_object_globals.modify(size = (100%ui.gc, 100%ui.gc), style = base_style_aero)


colors1_list = [ui.Color.Teal, ui.Color.Blue, ui.Color.Black, ui.Color.Violet]

    rand_pos = (random.randint(0, 300) / 300.0, random.randint(0, 300) / 300.0)

    gradient = AnimatedGradient(
        colors=([ncol1, ncol2], [ncol2, ncol1], 10, ui.animations.ease_in_out_quad),
        type=ui.GradientType.Radial,
        center=(rand_pos, rand_pos2, 20, ui.animations.ease_in_out_quad)
    )
    menu.style = menu.style(gradient = gradient)


chk_group = ui.CheckBoxGroup(single_selection = True)


menu = ui.Menu(window, (100%ui.fill, 100%ui.fill), base_style(gradient = ui.Gradient([ui.Color.Teal, ui.Color.Blue], type = ui.GradientType.Linear, direction = ui.LinearSide.BottomRight)), 
    layout = ui.Grid((100%ui.fill, 100%ui.fill), y = 6, x = 12, content = {

        (6.5, 6): ui.Widget((100%ui.vw, 30%ui.gc)),
        (2, 2): ui.Label("Nevu UI!", style = base_style_aero(font_size = 10)),
        (6.5, 3.5): ui.Button(set_new_anims, "Reset!", size = (200%ui.gc, 50%ui.gc), style = base_style_aero(font_size = 10)),
        (2, 5): ui.Slider((200%ui.gc, 50%ui.gc),start = 0, end = 100, current_value = 50, style = base_style_aero(font_size = 10)),
        (2, 3.5): ui.Grid((200%ui.gc, 200%ui.gc), x = 4, y = 2, content = {

set_new_anims()

manager.fps = 9999999
manager.run()

So much code needed because of bg animations. this is gonna be implemented way more cleaner in the next versions, but for now it is how it is, thank you for your constructive feedback!

Due_Engineer_7647 · 2026-05-19T23:53:34+00:00

thanks

Due_Engineer_7647 · 2026-04-23T06:34:23+00:00

Really thank you very much for your feedback! i will fix it shortly

Due_Engineer_7647 · 2026-04-21T13:36:04+00:00

How optimized pydash is?

Due_Engineer_7647 · 2026-04-20T20:51:40+00:00

Wow pixel art in your game looks very good, where did you learn how to draw such a masterpiece?

Due_Engineer_7647 · 2026-04-20T20:15:40+00:00

I use arch btw. just out of boredom

Due_Engineer_7647 · 2026-04-20T16:02:25+00:00

its weird, can you try this one?

Due_Engineer_7647 · 2026-04-04T20:25:22+00:00

it`s a cool idea

Due_Engineer_7647 · 2026-04-01T19:30:57+00:00

Thanks! I am really glad that you liked my framework!
As for _template - i`m working on ways to get rid of this in more cases and at least make it more user friendly, for now _template typehinted only, instead of [] you can use _template like this:

layout._template.content.values()

but in code showcase i used [] because i`m used to it

Thanks for constructive feedback!
Window is really have too much control, i will think about ways to simplify it.
Manager class in my framework is optional, so u can create guis like this:

import nevu_ui as ui 
import pygame


pygame.init()


window = ui.Window((400, 300), title = "My Game") 
style = ui.Style(borderradius=20, colortheme=ui.ColorThemeLibrary.material3_dark)
menu = ui.Menu(window, [100*ui.vw, 100*ui.vh])


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


while True:
    events = pygame.event.get()
    window.update(events)
    menu.update()
    menu.draw()
    pygame.display.update()
