PyQt5 QSpinBox - Getting MM Height Last Updated : 28 May, 2020 Comments Improve Suggest changes Like Article Like Report In this article we will see how we can get the MM Height of the spin box. MM Height is basically the height of the paint device in millimeters. Due to platform limitations it may not be possible to use this function to determine the actual physical size of a spin box on the screen. In order to do this we use heightMM method with the spin box object. Syntax : spin_box.heightMM() Argument : It takes no argument Return : It returns integer Below is the implementation Python3 1== # 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(1, 999999) # setting prefix to spin self.spin.setPrefix("PREFIX ") # setting suffix to spin self.spin.setSuffix(" SUFFIX") # creating a label label = QLabel(self) # making the label multi line label.setWordWrap(True) # setting geometry to the label label.setGeometry(100, 200, 200, 60) # getting MM Height of spin box value = self.spin.heightMM() # setting text to the label label.setText("MM Height = " + str(value)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) Output : Comment More infoAdvertise with us Next Article PyQt5 QSpinBox - Getting pixel size R rakshitarora Follow Improve Article Tags : Python Python-PyQt Python-gui Python PyQt-SpinBox Practice Tags : python Similar Reads PyQt5 QSpinBox - Getting height of font In this article we will see how we can get the height of the spin box's font i.e its text. Height is the vertical length of the text. Height of font is always equal to ascent +descent +1 (the 1 is for the base line). In order to do this we use height method with the spin box's QFontMetrics object.

Pixel size change the size of each pixel of the text there more the value of pixel the more text will get enlarged. We can change the pixel size with the help of setPixelSize method. In order to do this we use pixelSi 2 min read PyQt5 QSpinBox - Getting Pixel ratio In this article we will see how we can get the pixel ratio of the spin box, The device pixel ratio is the ratio between physical pixels and logical pixels of the spin box. Common values are 1 for normal-dpi displays and 2 for high-dpi "retina" displays. In order to do this we use devicePixelRatio me 2 min read PyQt5 QSpinBox - Getting right margin In this article we will see how we can get the right margin of the spin box, by default it is set to zero although we can change this using setRight method with the margin object of spin box.
