PyQt5 QSpinBox – 设置提示偏好
在这篇文章中,我们将看到如何获得旋转盒子字体的提示偏好,有不同级别的提示可以应用到字形上,以提高显示器上的可读性,这可能是由像素的密度决定的。我们可以在setHintingPreference方法的帮助下设置提示偏好。
为了做到这一点,我们使用hintingPreference方法来设置旋转框中的QFont对象
语法: font.hintingPreference()
参数: 它不需要参数
返回: 它返回preference对象,但当我们打印它时,它显示的是各自的preference值。
下面是实现方法
# 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()
# setting hinting preference
font.setHintingPreference(QFont.PreferFullHinting)
# 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 hitting preference
check = font.hintingPreference()
# setting text to the label
label.setText("Hitting Preference : " + str(check))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
