PyQt：如何创建自定义组合标题栏和菜单栏
问题描述
我想将菜单和标题设置在一个栏中，但不知道如何布局菜单栏和标题栏(或我自己的标题栏)。
# -*- coding:utf-8 -*-
from PyQt5 import QtWidgets,QtGui,QtCore
import sys
qss = ""
class UI(QtWidgets.QMainWindow):
def __init__(self):
super().__init__()
self.setui()
def setui(self):
#----------main-window----------------------
self.setGeometry(0,0,1366,768) #x,y,w,h
self.setWindowTitle('hello world')
self.setWindowFlag(QtCore.Qt.FramelessWindowHint)
#----------menu-bar---------------------
#--------file-menu-----
self.menu_file=self.menuBar().addMenu('file')
self.menu_file_open=self.menu_file.addAction('open')
self.menu_file_save=self.menu_file.addAction('save')
self.menu_file_saveas=self.menu_file.addAction('save as...')
self.menu_file_quit=self.menu_file.addAction('exit')
#-----------experient-menu----------
self.menu_work=self.menuBar().addMenu('work')
#-------------analysis-menu---------
self.menu_analysis=self.menuBar().addMenu('analysis')
#------------edit-menu--------------
self.menu_edit=self.menuBar().addMenu('edit')
#------------window-menu--------------
self.menu_window=self.menuBar().addMenu('window')
#------------help---menu--------------
self.menu_help=self.menuBar().addMenu('help')
#-------------set---qss----------------------
self.setStyleSheet(qss)
#-------functions--connect-------------------
self.menu_file_quit.triggered.connect(QtWidgets.qApp.quit)
self.show()
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
ex = UI()
sys.exit(app.exec_())
我希望栏包括图标、菜单、标题和这三个按钮，就像vscode的菜单栏一样。
解决方案
