如何自定义桌面应用程序的标题栏和窗口

Question

我如何自定义标题栏（包括：关闭，最大化，最小化按钮，标题）和用PyQt编写的桌面应用程序框架，使其看起来像下面的图像？我需要一种方法来指定我想用于标题栏元素的颜色（按钮，文本标题和条形和按钮的背景颜色）。

我需要更改其窗口的代码：

import sys
from PyQt5 import QtCore, uic
from PyQt5.QtWidgets import QApplication, QDialog

class MainWindow(QDialog):
    def __init__(self, parent=None):
        QDialog.__init__(self, parent)

        self.setWindowFlags(QtCore.Qt.FramelessWindowHint)


        self.resize(500, 600)

if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = MainWindow()
    sys.exit(app.exec_())

有没有办法做到这一点？我很欣赏这样做的任何建议和想法。
