class CurveWindow(BaseWidgetWindow):
    def __init__(self,w,h,color:tuple,roundness=50):
        super().__init__()
        self.setWindowFlag(Qt.FramelessWindowHint)
        self.setAttribute(Qt.WA_TranslucentBackground)
        self.rounded_widget=QWidget(self)
        self.rounded_widget.resize(w,h)
        self.resize(w,h)
        self.rounded_widget.setStyleSheet(f"""
            background:rgb({color[0]},{color[1]},{color[2]});
