PyQt5 QSpinBox - 制作旋转框解释文本
在本文中,我们将看到如何让旋转框解释文本。文本解释意味着检查文本并从中找到基本信息。如果自上次解释以来该值已更改,则将发出信号。
为了做到这一点,我们使用带有旋转框对象的interpretText
方法。
Syntax : spin_box.interpretText()
Argument : It takes no 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(1, 999999)
# setting prefix to spin
self.spin.setPrefix("PREFIX ")
# setting suffix to spin
self.spin.setSuffix(" SUFFIX")
# making spin box interprets the text
self.spin.interpretText()
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
