pyqt menu

Do you want a menu in your PyQt app?

Pyqt has menu support. Almost every GUI app has a main menu at the top of the window. Adding a menu works slightly different than adding widgets.

A menu can contain sub menus, they are usually something like (File, Edit, View, History, Help). Every menu has actions.

Pyqt menu example

The menu is created with:

menuBar = self.menuBar()
fileMenu = menuBar.addMenu('&File')

Then actions are added to the file menu:

fileMenu.addAction(newAction)
fileMenu.addAction(openAction)
fileMenu.addAction(exitAction)

These actions must be defined beforehand:

# Create new action
newAction = QAction(QIcon('new.png'), '&New', self)
newAction.setShortcut('Ctrl+N')
newAction.setStatusTip('New document')
newAction.triggered.connect(self.newCall)

# Create new action
openAction = QAction(QIcon('open.png'), '&Open', self)
openAction.setShortcut('Ctrl+O')
openAction.setStatusTip('Open document')
openAction.triggered.connect(self.openCall)

# Create exit action
exitAction = QAction(QIcon('exit.png'), '&Exit', self)
exitAction.setShortcut('Ctrl+Q')
exitAction.setStatusTip('Exit application')
exitAction.triggered.connect(self.exitCall)

Complete code:

import sys
from PyQt5 import QtCore, QtWidgets
from PyQt5.QtWidgets import QMainWindow, QWidget, QPushButton, QAction
from PyQt5.QtCore import QSize
from PyQt5.QtGui import QIcon

class MainWindow(QMainWindow):
def __init__(self):
QMainWindow.__init__(self)

self.setMinimumSize(QSize(300, 100))
self.setWindowTitle("PyQt menu example - pythonprogramminglanguage.com")

# Add button widget
pybutton = QPushButton('Pyqt', self)
pybutton.clicked.connect(self.clickMethod)
pybutton.resize(100,32)
pybutton.move(130, 30)
pybutton.setToolTip('This is a tooltip message.')

# Create new action
newAction = QAction(QIcon('new.png'), '&New', self)
newAction.setShortcut('Ctrl+N')
newAction.setStatusTip('New document')
newAction.triggered.connect(self.newCall)

# Create new action
openAction = QAction(QIcon('open.png'), '&Open', self)
openAction.setShortcut('Ctrl+O')
openAction.setStatusTip('Open document')
openAction.triggered.connect(self.openCall)

# Create exit action
exitAction = QAction(QIcon('exit.png'), '&Exit', self)
exitAction.setShortcut('Ctrl+Q')
exitAction.setStatusTip('Exit application')
exitAction.triggered.connect(self.exitCall)

# Create menu bar and add action
menuBar = self.menuBar()
fileMenu = menuBar.addMenu('&File')
fileMenu.addAction(newAction)
fileMenu.addAction(openAction)
fileMenu.addAction(exitAction)

def openCall(self):
print('Open')

def newCall(self):
print('New')

def exitCall(self):
print('Exit app')

def clickMethod(self):
print('PyQt')

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