PyQt5 QSpinBox – 从子区域获取翻译区域
在这篇文章中,我们将看到如何从自旋盒的子区域获取翻译区域,子区域持有自旋盒的子区域所占据的组合区域。为了获得子区域,我们使用childrenRegion方法。平移区域意味着沿x和y轴移动子区域。
为了做到这一点,我们使用旋转盒的子区域对象的翻译方法
语法: children_region.translate(x, y)
参数: 它需要两个整数作为参数。
返回: 它返回QRegion
注意: 这个方法类似于translate方法,但是,这个方法不会对子区域进行改变。
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 children region
children_region = self.spin.childrenRegion()
# creating a label
label = QLabel(self)
label.setWordWrap(True)
# setting geometry to the label
label.setGeometry(100, 200, 200, 60)
# getting translated region from the children region
translated_region = children_region.translated(100, 100)
# setting text to the label
label.setText("Translated region : " + str(translated_region.rects()))
# 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 :
