In this article we will see how we can get the dock location changed signal 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).
This signal is emitted when the dock widget is moved to another dock area, or is moved to a different location in its current dock area. This happens when the dock widget is moved programmatically or is dragged to a new location by the user.
In order to do this we will use
dockLocationChanged
method with the dock widget object.Syntax : dock.dockLocationChanged.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( self )
# setting title to the dock widget
dock.setWindowTitle( "GfG Dock" )
# push button
push = QPushButton( "Press" , self )
dock.setAllowedAreas(Qt.NoDockWidgetArea)
# 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 )
# setting geometry tot he dock widget
dock.setGeometry( 100 , 0 , 200 , 30 )
# getting dock location changed signal
# setting text to the label
dock.dockLocationChanged.connect( lambda : label.setText( "Dock Location Changed Signal Emitted" ))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
