PyQt5 QSpinBox – Checking if text is bold ?
In this article we will see how we can check if the text of the spin box is bold not, in order to set the font use setFont method which takes QFont object as argument. In order to make the text i.e font bold we have to get the QFont object of the spin box then make it bold then reassign it to the spin box. In order to get the information about the font we have to get the QFontInfo object of spin box which can be done using fontInfo method.
In order to do this we bold method with the QFontInfo object of the spin box
Syntax : font_info.bold()
Argument : It takes no argument
Return : It returns bool
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 , 600 , 400 ) # calling method self .UiComponents() # showing all the widgets self .show() # method for widgets def UiComponents( self ): # creating spin box self .spin = QSpinBox( self ) # setting geometry to spin box self .spin.setGeometry( 100 , 100 , 250 , 40 ) # setting range to the spin box self .spin.setRange( 0 , 999999 ) # setting prefix to spin self .spin.setPrefix("PREFIX ") # setting suffix to spin self .spin.setSuffix(" SUFFIX") # getting font of the spin box font = self .spin.font() # making font bold font.setBold( True ) # reassigning the font to the spin box self .spin.setFont(font) # creating a label label = QLabel( self ) # setting geometry to the label label.setGeometry( 100 , 200 , 300 , 60 ) # getting the font info font_info = self .spin.fontInfo() # getting bold status of text check = font_info.bold() # setting text to the label label.setText("Bold ? : " + str (check)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
