PyQt5 QSpinBox – 从中获取像素图

在本文中，我们将了解如何获得旋转框限制的像素图。如果旋转框有任何孩子，那么它们也会被绘制在适当的位置。

注意：这个函数可以通过元对象系统和 QML 调用。

为了做到这一点，我们使用带有旋转框对象的grab方法。

Syntax : spin_box.grab(rectangle)

Argument : It takes QRect object as argument

Return : It returns QPixmap object

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 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 label multi line
        label.setWordWrap(True)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 60)
  
        # getting the current geometry
        geometry = self.spin.geometry()
  
        # getting the pixmap from the spin box
        pixmap = self.spin.grab(geometry)
  
        # setting text to the label
        label.setText(str(pixmap))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
