In this article we will see how we can get the floating point size of the text in spin box. Changing the point size will change the size of the text, pixel and point are two different things some point can have multiple pixels inside it. It is recommended to change point size for changing the size of the text. Unlike normal point size, floating point size can make the point size in decimal as point size is not a pixel its value can be in float as well there for normal get method will not get the float value as it get only integer value. In order to do this we use pointSizeF method with the QFont object of the spin box
Syntax : font.pointSizeF() Argument : It takes no argument Return : It returns float value
Below is the implementation
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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() # setting point size F font.setPointSizeF(20.25) # reassigning this 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 point size F p_size = font.pointSizeF() # setting text to the label label.setText("Floating Point Size : " + str(p_size))# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
