In this article we will see how we can get the minimum left bearing of the spin box’s font. Minimum left bearing value is the smallest leftBearing value of all characters in the font. The left bearing is the right-ward distance of the left-most pixel of the character from the logical origin of the character. This value is negative if the pixels of the character extend to the left of the logical origin.
In order to do this we use minLeftBearing() method with the spin box’s QFontMetrics object.
Syntax : font_metrics.minLeftBearing()
Argument : It takes no argument
Return : It returns integer.
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(1, 999999) # setting prefix to spin self.spin.setPrefix("PREFIX ") # setting suffix to spin self.spin.setSuffix(" SUFFIX") # setting under line to the font font = self.spin.font() font.setUnderline(True) self.spin.setFont(font) # 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() # getting minimum left bearing value value = f_metrics.minLeftBearing() # setting text to the label label.setText("Min left bearing value : " + 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 :
