PyQt5 QSpinBox – 检查文本是否大写
在这篇文章中,我们将看到如何检查旋转框的文本是否大写,为了设置字体,我们使用setFont方法,该方法以QFont对象为参数。为了使文本(即字体)大写,我们必须获得旋钮箱的QFont对象,然后使其大写,再将其重新分配给旋钮箱。
为了做到这一点,我们用自旋盒的QFont对象来实现大写方法
语法: font.capitalization()
参数: 它不需要参数
返回: 如果大写字母没有被打开,它返回二进制值0;如果被打开,它返回1。
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()
# making font capitalize
font.setCapitalization(True)
# reassigning the 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 capitalize status of text
check = font.capitalization()
# setting text to the label
label.setText("Capitalize ? : " + 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。
