PyQt5 QSpinBox - 确保抛光
在本文中,我们将了解如何确保旋转框被抛光。微调框的抛光是通过使用 QStyle 或使用样式表来完成的。完成所有编辑后,最后进行抛光,尽管开发人员可以使用ensurePolished
方法确保完成抛光。
In order to do this we use ensurePolished method
Syntax : spin_box.ensurePolished()
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(0, 999999)
# setting prefix to spin
self.spin.setPrefix("Prefix ")
# setting suffix to spin
self.spin.setSuffix(" Suffix")
# ensuring spin box is polished
self.spin.ensurePolished()
# setting style sheet
self.spin.setStyleSheet("QSpinBox"
"{"
"border : 2px solid black;"
"background : lightgray;"
"}"
"QSpinBox::hover"
"{"
"background : lightblue;"
"}")
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
