PyQt5 QSpinBox – 检查它是否加速了
在这篇文章中,我们将看到如何检查旋转盒是否被加速了。加速旋转盒意味着在按下升/降阶梯按钮时,加快了阶梯的频率。如果旋转盒被设置为加速,那么你按下按钮的时间越长,它就会更快地增加/减少数值。默认情况下,旋转盒不会加速,尽管我们可以使用setAccelerated方法使旋转盒加速。
为了做到这一点,我们在旋转盒对象中使用isAccelerated方法。
语法: spin_box.isAccelerated()
参数: 它不需要参数
返回: 它返回bool
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(1, 999999)
# setting prefix to spin
self.spin.setPrefix("PREFIX ")
# setting suffix to spin
self.spin.setSuffix(" SUFFIX")
# making spin box accelerate
self.spin.setAccelerated(True)
# creating a label
label = QLabel(self)
# making the label multi line
label.setWordWrap(True)
# setting geometry to the label
label.setGeometry(100, 200, 200, 60)
# checking if spin box is accelerated
check = self.spin.isAccelerated()
# setting text to the label
label.setText("Accelerated ? : " + 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:
