同样一份代码,

import sys
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from default import *

class TitleBar(QWidget):
    def __init__(self, parent):
        super(TitleBar, self).__init__()
        self.win = parent
        self.InitializeWindow()

    def InitializeWindow(self):
        self.isPressed = False
        self.setFixedHeight(TITLE_BAR_HEIGHT)
        self.InitializeViews()
        pass

    def InitializeViews(self):
        self.iconLabel = QLabel(self)
        self.titleLabel = QLabel(self)

        #设置标题栏的字体或者样式
        # self.titleLabel.setProperty('class', 'title_style')  # 设置样式表类
        self.titleLabel.setObjectName('titleLabel')

        self.minButton = QPushButton(self)

        self.closeButton.setFixedSize(TITLE_BUTTON_SIZE, TITLE_BUTTON_SIZE);

        self.lay.setSpacing(0)
        self.lay.setContentsMargins(0, 0, 0, 0)

        # 创建一个占位控件，并设置其最小宽度为20px
        # spacer = QWidget(self)
        # spacer.setFixedWidth(20)  # 这将使得图标向右移动20px
        # spacer.setObjectName('Spacer') 


        # self.lay.addWidget(spacer) 

        self.lay.addWidget(self.iconLabel)
        self.lay.addWidget(self.titleLabel)
        self.lay.addWidget(self.minButton)
        self.lay.addWidget(self.restoreButton)

        return QWidget().mouseMoveEvent(event)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    win = TitleBar(None)
    win.show()
    sys.exit(app.exec_())
    pass

写着写着,发现运行效果有点怪,右边的按钮莫名其妙多出来一个蓝色的圆框,
