PyQt5 QSpinBox – 访问家族名称
在本文中,我们将了解如何获取旋转框字体的姓氏。家族名称还可以可选地包括铸造厂名称,例如“Helvetica [Cronyx]”。如果该系列可从多个代工厂获得且未指定代工厂,则选择任意代工厂。如果系列不可用,将使用字体匹配算法设置系列。为了设置姓氏,我们使用setFamily
方法。
为了获得关于字体的信息,我们必须获得旋转框的 QFontInfo 对象,这可以使用fontInfo
方法来完成。
In order to do this we family method with the QFontInfo object of the spin box
Syntax : font_info.family()
Argument : It takes no argument
Return : It returns string
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")
# creating a label
label = QLabel(self)
# setting geometry to the label
label.setGeometry(100, 200, 300, 60)
# getting the font info
font_info = self.spin.fontInfo()
# getting family name
name = font_info.family()
# setting text to the label
label.setText("Family Name : " + name)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
