PyQt5 QDockWidget – Getting Graphics Effect Object

In this article we will see how we can get Graphic effect object of 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). Graphic effect can be shadow, blur, color or even customized effect, it is used for making dock widget attractive. By default there is no graphic effect, it can be set with the help of setGraphicsEffect method.

In order to do this we will use graphicsEffect method with the dock widget object.
Syntax : dock.graphicsEffect()
Argument : It takes no argument
Return : It returns QGraphicEffect object 

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 Title")

        # 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)

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

        # 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 to the dock widget
        dock.setGeometry(100, 0, 200, 30)


        # color effect
        color = QGraphicsColorizeEffect(self)

        # setting green color to the effect
        color.setColor(Qt.darkGreen)

        # setting graphic effect to the dock
        dock.setGraphicsEffect(color)

        # getting graphic effect
        value = dock.graphicsEffect()

        # setting text to the label
        label.setText("Graphic Effect : " + str(value))







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

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

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

Output :
