PyQt: How to create custom combined titlebar and menubar
I'd like to set the menu and title in one bar, but have no idea that how to layout the menu bar and title bar (or my own title bar).
# -*- 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_())
I expect a bar include icon, menus, title and the three buttons, just like the menu bar of vscode.

Try it:
