In this article we will see how we can check if the mouse tracking of the combo box is activated or not, combo box receive signal about the mouse when any button is pressed but after mouse tracking it will receive all the signals about the mouse even if any button is not pressed. By default this property is False although we can activate mouse tracking with the help of setMouseTracking
method.
In order to do this we use hasMouseTracking
method
Syntax : combo_box.hasMouseTracking()
Argument : It takes no argument
Return : It returns bool
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 , 600 , 400 )
# calling method
self .UiComponents()
# showing all the widgets
self .show()
# method for widgets
def UiComponents( self ):
# creating a check-able combo box object
self .combo_box = QComboBox( self )
# setting geometry of combo box
self .combo_box.setGeometry( 200 , 150 , 100 , 30 )
# geek list
geek_list = [ "Sayian" , "Super Sayian" , "Super Sayian 2" , "Super Sayian B" ]
# adding list of items to combo box
self .combo_box.addItems(geek_list)
# setting mouse tracking
self .combo_box.setMouseTracking( True )
# setting stylesheet of the combo box
self .combo_box.setStyleSheet( "border : 1px solid red;" )
# creating label
label = QLabel( self )
# setting geometry to the label
label.setGeometry( 200 , 200 , 200 , 40 )
# getting mouse tracking
tracking = self .combo_box.hasMouseTracking()
# setting text to the label
label.setText( "Mouse tracking enabled ? : " + str (tracking))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
