Creating a Custom Combined Title Bar and Menu Bar in PyQt5

PyQt5 is a powerful library for creating desktop applications with Python. In this tutorial, we will learn how to create a custom combined title bar and menu bar in PyQt5.

Step 1: Create a Main Window

First, we need to create a main window for our application. We can do this by using the QMainWindow class in PyQt5.

“`python
import sys
from PyQt5.QtWidgets import QMainWindow, QApplication

class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.setWindowTitle(‘Custom Title Bar and Menu Bar’)
self.setGeometry(100, 100, 800, 600)

if __name__ == ‘__main__’:
app = QApplication(sys.argv)
mainWindow = MainWindow()
mainWindow.show()
sys.exit(app.exec_())
“`

Step 2: Create a Custom Title Bar

Next, we will create a custom title bar for our application. We can do this by removing the default title bar and creating our own custom widget.

“`python
from PyQt5.QtWidgets import QWidget, QHBoxLayout, QLabel

class CustomTitleBar(QWidget):
def __init__(self, parent):
super().__init__(parent)
layout = QHBoxLayout()

title = QLabel(‘Custom Title’)
layout.addWidget(title)

self.setLayout(layout)
“`

Step 3: Add the Custom Title Bar to the Main Window

Finally, we will add the custom title bar to the main window by setting the window title bar widget to our custom title bar widget.

“`python
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.setWindowTitle(‘Custom Title Bar and Menu Bar’)
self.setGeometry(100, 100, 800, 600)

customTitleBar = CustomTitleBar(self)
self.setMenuWidget(customTitleBar)
“`

Step 4: Add a Menu Bar

Now, let’s add a menu bar to our custom title bar. We can add actions, menus, and submenus to the menu bar just like in a regular QMainWindow.

“`python
from PyQt5.QtWidgets import QAction, QMenu

class CustomTitleBar(QWidget):
def __init__(self, parent):
super().__init__(parent)
layout = QHBoxLayout()

self.menuBar = self.createMenuBar()
layout.addWidget(self.menuBar)

title = QLabel(‘Custom Title’)
layout.addWidget(title)

self.setLayout(layout)

def createMenuBar(self):
menuBar = QMenu()

fileMenu = menuBar.addMenu(‘File’)
fileMenu.addAction(‘New’)
fileMenu.addAction(‘Open’)

editMenu = menuBar.addMenu(‘Edit’)
editMenu.addAction(‘Cut’)
editMenu.addAction(‘Copy’)
editMenu.addAction(‘Paste’)

return menuBar
“`

Conclusion

By following these steps, you can create a custom combined title bar and menu bar in PyQt5. This will give your desktop application a unique and personalized look and feel. Experiment with different styles and designs to create the perfect title bar and menu bar for your application.
