PyQt5 QSpinBox – 如何保存其几何形状
在这篇文章中,我们将看到如何保存旋转盒的几何图形。保存几何图形有助于保存当前的几何图形和顶层旋转盒小部件的状态。保存的数据可以存储在任何外部文件中,也可以恢复用于其他用途。
为了做到这一点,我们使用旋转盒对象的saveGeometry方法。
语法: spin_box.saveGeometry()
参数: 它不需要参数
返回: 它返回QByteArray对象
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(1, 999999)
# setting prefix to spin
self.spin.setPrefix("PREFIX ")
# setting suffix to spin
self.spin.setSuffix(" SUFFIX")
# creating a label
label = QLabel(self)
# making the label multi line
label.setWordWrap(True)
# setting geometry to the label
label.setGeometry(100, 200, 200, 60)
# saving the geometry
value = self.spin.saveGeometry()
# setting text to the label
label.setText("Saved geometry : " + str(value))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出:
