[Python3 SDL2] Podstawowe elementy GUI czyli Buttony » 2025-07-20 19:53:59 Cześć. Uczę się od niedawna Python3 i SDL2. Chciałbym stworzyć ładny przycisk z tekstem. Jak się za to najlepeij zabrać ? Poniżej zamieszczam ogólny kod przycisku (bez tekstu z ramką), który działa. Button.py
import sdl2
import sdl2.ext
import numpy as np
class Button:
x : int
y : int
wdt : int
hgh : int
r : int
g : int
b : int
def __init__(self, x : int, y : int, width: int, height: int):
self.x = x
self.y = y
self.wdt = width
self.hgh = height
self.set_color(64, 64, 64)
def set_color(self, r : int, g : int, b : int):
self.r = r
self.g = g
self.b = b
def cursorHover(self, mouse_x : int, mouse_y : int) -> bool:
if( mouse_x >= self.x and mouse_y >= self.y and mouse_x <= self.x + self.wdt and mouse_y <= self.y + self.hgh):
self.set_color(128, 128, 128)
return True
else:
self.set_color(64, 64, 64)
return False;
def draw(self, renderer):
renderer.color = sdl2.ext.Color(32, 32, 32)
rect = sdl2.SDL_Rect(self.x, self.y, self.wdt, self.hgh)
renderer.fill(rect)
margin = 4
renderer.color = sdl2.ext.Color(self.r, self.g, self.b)
rect = sdl2.SDL_Rect(self.x + margin, self.y + margin, self.wdt - 2*margin, self.hgh-2*margin)
renderer.fill(rect)
