PyQt5 QSpinBox – 获取子区域
在本文中,我们将了解如何获取子区域,子区域包含旋转框的子区域所占据的组合区域。为了做到这一点,我们使用childrenRegion
方法。如果我们删除旋转框的所有子元素,则此属性将返回一个空区域。
为了做到这一点,我们使用 childrenRegion 方法。
Syntax : spin_box.childrenRegion()
Argument : It takes no argument
Return : It returns QRegion object
注意:不包括隐藏的孩子
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
self.label = QLabel("Label ", self)
# setting geometry to the label
self.label.setGeometry(100, 200, 200, 70)
# getting the children region
children_region = self.spin.childrenRegion()
# setting text to the label
self.label.setText(str(children_region))
# making label multi line
self.label.setWordWrap(True)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
