PyQt5 QDockWidget – Setting Widget to it

  • Last Updated : 28 Jul, 2020

In this article we will see how we can set widget 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). Dock windows can be moved inside their current area, moved into new areas and floated (e.g., undocked) by the end-user.

We can add widget to the dock widget, widget can any widget or even a single widget which contains many small child widgets. Along with dock widget the widget set to it also moves with it.

In order to do this we will use setWidget method with the dock widget object.

Syntax : dock.setWidget(widget)

Argument : It takes QWidget as argument



Return : It returns None

Below is the implementation




# 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("GeeksforGeeks", self)
  
        # push button
        push = QPushButton("Press", self)
  
        # setting widget to the dock
        dock.setWidget(push)
  
        # setting geometry tot he dock widget
        dock.setGeometry(100, 0, 200, 30)
  
  
        # 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)
  
        # adding action to the push button
        push.clicked.connect(lambda: label.setText("Dock Widget's Push button pressed"))
  
  
  
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
