In this article we will see how we can get feature change signal of 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). There are many features already enabled for the dock, also there are feature like movable, closable, floatable, horizontal title bar or there is a option of setting all features or setting no features, these can be set with the help of setFeatures method. Feature change signal is emitted when the feature of the dock is changed.
In order to do this we will use featuresChanged method with the dock widget object. Syntax : dock.featuresChanged.connect(method) Argument : It takes method 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)
# 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 )
# getting feature changed signal
# setting text to the label when feature is changed
dock.featuresChanged.connect( lambda : label.setText("Feature Changed"))
# setting feature to the dock
dock.setFeatures(QDockWidget.DockWidgetClosable)
# 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 ())
