PyQt5 QDockWidget – Setting Title Bar widget

In this article we will see how we can set title bar widget to the QDockWidget. QDockWidget provides the concept of dock widgets, also known as tool palettes or utility windows. Dock windows are secondary windows placed in the dock widget area around the central widget in a QMainWindow(original window). Title bar widget is the widget that consist of the title and the options available for it, although we can change this any time.

In order to do this we will use setTitleBarWidget method with the dock widget object.
Syntax : dock.setTitleBarWidget(widget)
Argument : It takes QWidget object as argument
Return : It returns None 

Below is the implementation 

Python3

# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys


class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 500, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

    # method for components
    def UiComponents(self):

        # creating dock widget
        dock = QDockWidget(self)

        # setting title to the dock widget
        dock.setWindowTitle("                   GfG ")


        # push button
        push = QPushButton("Press", self)

        # setting widget to the dock
        dock.setWidget(push)

        # creating a label
        label = QLabel("GeesforGeeks", self)

        # setting geometry to the label
        label.setGeometry(100, 200, 300, 80)

        # making label multi line
        label.setWordWrap(True)

        # setting geometry tot he dock widget
        dock.setGeometry(100, 0, 200, 30)

        # creating a label
        widget = QLabel("Geeks", self)

        # setting title bar widget to the dock
        dock.setTitleBarWidget(widget)

# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
