PyQt5 – Setting and accessing name of a Label
While designing a Gui (Graphical User Interface) application, we mostly end up making lots of labels. For back-end coders, it become tough to distinguish between the label. To overcome this situation, need of settings label name is required, for examples among hundreds of label we can distinguish them by setting their names like some are “info” labels, some are “warning” labels just like this.
A label is generally a graphical control element which displays text on a form. It is usually a static control; having no interactivity. A label is generally used to identify a nearby text box or other widget.
To set the Name –
Syntax : label.setAccessibleName(name)
Argument : It takes string as argument.
Return : No return value.
To access the Name –
Syntax : label.accessibleName()
Argument : It takes no argument.
Return : It returns string.
Code :
# importing the required libraries from PyQt5.QtWidgets import * from PyQt5 import QtCore from PyQt5 import QtGui import sys class Window(QMainWindow): def __init__( self ): super ().__init__() # set the title self .setWindowTitle( "Name" ) # setting the geometry of window self .setGeometry( 0 , 0 , 400 , 300 ) # creating a label widget self .label_1 = QLabel( "Label" , self ) # moving position self .label_1.move( 100 , 100 ) # setting up border self .label_1.setStyleSheet( "border: 1px solid black;" ) # setting up the name of label_1 self .label_1.setAccessibleName( "Info" ) # getting name of label_1 name = self .label_1.accessibleName() # new label to display name self .label_2 = QLabel(name, self ) self .label_2.move( 100 , 130 ) self .label_2.adjustSize() # show all the widgets self .show() # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
