PyQt5 QSpinBox – 设置字距
在本文中,我们将了解如何设置或禁用旋转框文本的字距调整。在排版中,字距调整是按比例字体调整字符间距的过程,通常是为了获得视觉上令人愉悦的结果。字距调整单个字母形式之间的间距,而跟踪则在一系列字符上均匀地调整间距。默认情况下,此属性为 True。
下面是字距调整效果的表示
为了做到这一点,我们使用setKerning
方法和旋转框的 QFont 对象
Syntax : font.setKerning(False)
Argument : It takes bool as argument
Return : It returns None
下面是实现
# 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()
# disabling the kerning effect
font.setKerning(False)
# reassigning this font to the spin box
self.spin.setFont(font)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
