如何在 PyQt QFrame 中制作有角度的箭头型边框？在我的代码中，我有两个 QLabel 和各自的框架。我的目标是在每个 QFrame 的右侧制作一个箭头形状的边框。为了获得清晰的想法，请附上示例图片。

import sys
from PyQt5.QtWidgets import *

class Angle_Border(QWidget):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("Angle Border")

        self.lbl1 = QLabel("Python")
        self.lbl2 = QLabel("PyQt")

        self.frame1 = QFrame()
        self.frame1.setProperty("type","1")
        self.frame1.setFixedSize(200,50)
        self.frame1.setStyleSheet("background-color:red;color:white;"
                                  "font-family:Trebuchet MS;font-size: 15pt;text-align: center;"
                                  "border-top-right-radius:25px solid ; border-bottom-right-radius:25px solid ;")
        self.frame2 = QFrame()
        self.frame2.setFixedSize(200, 50)
        self.frame2.setStyleSheet("background-color:blue;color:white;"
                                  "font-family:Trebuchet MS;font-size: 15pt;text-align: center;"
                                  "border-top:1px solid transparent; border-bottom:1px solid  transparent;")
        self.frame_outer = QFrame()
        self.frame_outer.setFixedSize(800, 60)
        self.frame_outer.setStyleSheet("background-color:green;color:white;"
                                  "font-family:Trebuchet MS;font-size: 15pt;text-align: center;")

        self.frame1_layout = QHBoxLayout(self.frame1)
        self.frame2_layout = QHBoxLayout(self.frame2)
        self.frame_outer_layout = QHBoxLayout(self.frame_outer)
        self.frame_outer_layout.setContentsMargins(5,0,0,0)

        self.frame1_layout.addWidget(self.lbl1) …
