PyQt5 QSpinBox – Checking if the character is UTF-32 format
In this article we will see how we can check if the given character in the font of the spin box is in UTF-32 format. UTF-32 is a fixed-length encoding used to encode Unicode code points that uses exactly 32 bits per code point. UTF-32 is a fixed-length encoding, in contrast to all other Unicode transformation formats, which are variable-length encodings.
In order to do this we use inFontUcs4 method with the spin box’s QFontMetrics object.
Syntax : font_metrics.inFontUcs4(unit_character)
Argument : It takes integer as 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 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") # creating a label label = QLabel(self) # making label multi line label.setWordWrap(True) # setting geometry to the label label.setGeometry(100, 200, 300, 60) # getting font metrics f_metrics = self.spin.fontMetrics() # checking if the character is in the font check = f_metrics.inFontUcs4(1) # setting text to the label label.setText(" UTF Format : " + str(check)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
