PyQt5 QSpinBox – 让它加速
在这篇文章中,我们将看到如何使旋转盒加速。加速旋转盒意味着在按下升/降阶梯按钮时加快步幅的频率。如果旋转箱被设置为加速,那么你按下按钮的时间越长,它就会更快地增加/减少数值。
为了做到这一点,我们使用旋转盒对象的setAccelerated方法。
语法: spin_box.setAccelerated(True)
参数: 它以bool作为参数
返回: 它返回无。
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)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
