PyQt5 QSpinBox - 检查是否启用了自动填充背景属性
在本文中,我们将了解如何查看旋转框的自动填充属性是否启用,该属性将导致 Qt 在调用绘制事件之前填充旋转框的背景。使用的颜色由旋转框调色板中的QPalette.Window
颜色角色定义。默认情况下,此属性为 false,尽管我们可以使用setAutoFillBackground
方法更改此属性。
为此,我们使用 autoFillBackground 方法。
Syntax : spin_box.autoFillBackground()
Argument : It takes no argument
Return : It returns bool
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 prefix to spin
self.spin.setPrefix("Prefix ")
# setting suffix to spin
self.spin.setSuffix(" Suffix")
# creating a label
label = QLabel(self)
# setting geometry to the label
label.setGeometry(100, 200, 300, 30)
# checking if auto fill background is enabled
check = self.autoFillBackground()
# setting text to the label
label.setText("Auto Fill Background Enabled ? : " + 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 :
