PyQt5 QSpinBox – 在行下设置
在本文中,我们将看到如何为旋转框设置下划线。下划线,也称为下划线,是紧挨部分文字下方的或多或少的水平线。在手写或打字文档中使用单下划线和偶尔双下划线作为强调关键文本的一种方式。下面是旋转框的下划线文本的样子
为了做到这一点,我们将setUnderline
方法与旋转框的 QFont 对象一起使用。
Syntax : font.setUnderline(True)
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()
# setting under line
font.setUnderline(True)
# 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())
输出 :
