PyQt5 QDockWidget – Setting Multiple Widgets Inside it

24 May, 2022
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 following1. 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 librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom 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("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)    # create pyqt5 appApp = QApplication(sys.argv) # create the instance of our Windowwindow = Window() # start the appsys.exit(App.exec())
