Usage

import os
import sys
from PySide6.QtGui import QColor
from PySide6.QtCore import QSize, Qt
from Qtica.services import randomColor, colorToHex
from Qtica.widgets import MainWindow, Label, Application
from Qtica import BehaviorDec, Api


class Window(BehaviorDec):
    def get_text_color(self, color: QColor) -> QColor:
        luma = ((0.299 * color.red()) + (0.587 * color.green()) + (0.114 * color.blue())) / 255
        return QColor(0, 0, 0) if luma > 0.5 else QColor(255, 255, 255)

    def update_background(self):
        bg_color = randomColor()
        fg_color = self.get_text_color(bg_color)

        Api.fetch("window").qss.update({"background-color": bg_color.name()})
        Api.fetch("label").qss.update({"color": fg_color.name()})

    def __init__(self):
        return MainWindow(
            uid="window",
            windowTitle="Welcome Qtica!",
            methods = [
                ("resize", QSize(400, 200))
            ],
            events = [
                ("mousePress", lambda _: self.update_background())
            ],
            home=Label(
                uid="label",
                setText=f"Hello {os.environ.get('USER', '')}, Welcome to Qtica.<br>Click me!",
                setTextFormat=Qt.TextFormat.RichText,
                setAlignment=Qt.AlignmentFlag.AlignCenter,
                qss={"font-size": "24px"}
            ),
            qss={"background-color": colorToHex(randomColor())},
        )

app = Application(sys.argv)
window = Window()
window.show()
sys.exit(app.exec())
