In this article we will see how we can get the window title 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).
Window title property holds the dock widget title (caption), it can be set with the help of setWindowTitle
method. This signal is emitted when the dick widget window’s title has changed.
In order to do this we will use
windowTitleChanged
method with the dock widget object.Syntax : dock.windowTitleChanged.connect(method)
Argument : It takes method as argument
Return : It returns None
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 Dock" ) # push button push = QPushButton( "Press" , self ) # setting floating property dock.setFloating( False ) # setting widget to the dock dock.setWidget(push) # creating a label label = QLabel( "neveropen" , 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 window title changed signal # setting text to the label dock.windowTitleChanged.connect( lambda : label.setText( "Title Changed Signal Emitted" )) # changing title of dock widget dock.setWindowTitle( "neveropen" ) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
