PyQt5 QSpinBox – 获取属性值
在这篇文章中,我们将看到如何获取旋转盒的属性值,属性是由开发者添加的信息,用于告诉旋转盒的属性,例如,如果旋转盒有循环取值的能力,开发者将添加这个属性,以便其他开发者可以看到这个属性并了解这个属性。属性是通过setProperty方法添加的。
为了做到这一点,我们使用属性方法
语法: spin_box.property(property)
参数: 它使用字符串作为参数
返回: 它返回整数
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")
# adding property to the spin box
self.spin.setProperty("Dynamic", 1)
# adding property to the spin box
self.spin.setProperty("Has suffix", 1)
# creating label
self.label = QLabel(self)
# setting geometry to the label
self.label.setGeometry(100, 200, 200, 70)
# making it multi line label
self.label.setWordWrap(True)
# property
property_name = "Dynamic"
# getting property value
value = self.spin.property(property_name)
# setting text to the label
self.label.setText("Property Name : " + property_name +
" Property Value : " + str(value))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
window.spin.setFocus()
# start the app
sys.exit(App.exec())
输出 :
