PyQt5 QSpinBox – 为文本设置权重
在这篇文章中,我们将看到如何为旋转框的文本设置重量。Font-weight是用来设置字体的重量(粗体)的。权重的值越大,文本就越粗。
为了做到这一点,我们使用了旋转框的QFont对象的setWeight方法。
语法: font.setWeight(n)
参数: 它需要整数作为参数。
返回: 它返回无。
以下是实现方法
# 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 weight to the font
font.setWeight(75)
# 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:
