PyQt5 QDockWidget – Setting Multiple Widgets Inside it

Last Updated : 14 Jan, 2023

In this article we will see how we add/set multiple widgets to the QDockWidget. QDockWidget provides the concept of dock widgets, also know 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). We use setWidget method to add/set widget to the dock widget. But this is used to set only single widget.

In order to set multiple widgets inside it we have to do the following
1. Create a Main Window Class
2. Inside the class create a QDockWidget object and set its properties
3. Create a QWidget object
4. Create a QLayout object
5. Create various widget object which we want to add in the QDockWidget
6. Add these widgets to the layout created earlier with the help of addWidget method
7. Set this layout to the QWidget object with the help of setLayout method
8. Set this QWidget object to the QDockWidget object with the help of setWidget method

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 ")

        # creating a QWidget object
        widget = QWidget(self)

        # creating a vertical box layout
        layout = QVBoxLayout(self)

        # push button 1
        push1 = QPushButton("A", self)

        # push button 2
        push2 = QPushButton("B", self)

        # push button 3
        push3 = QPushButton("C", self)

        # adding these buttons to the layout
        layout.addWidget(push1)
        layout.addWidget(push2)
        layout.addWidget(push3)

        # setting the layout to the widget
        widget.setLayout(layout)

        # adding widget to the layout
        dock.setWidget(widget)

        # creating a label
        label = QLabel("GeeksforGeeks", 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)




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

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

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