PyQt5 QSpinBox – 如何设置遮罩
在这篇文章中,我们将看到如何为旋转盒设置遮罩,遮罩基本上是用来隐藏旋转盒的,在遮罩的帮助下,用户将无法看到整个旋转盒,尽管旋转盒仍然存在,但上面会有遮罩。
为了做到这一点,我们使用setMask方法。
语法: spin_box.setMask(region)
参数: 它接受QRegion对象或QBitMap对象作为参数。
返回: 它返回无。
下面是实现方法
# 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")
# getting the region of children of spin box
region = self.spin.childrenRegion()
# setting mask
self.spin.setMask(region)
# 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:
