PyQt5 QSpinBox – 根据值调整大小

在本文中，我们将了解如何根据旋转框的值调整其大小。我们可以在setGeometry方法的帮助下设置旋转框的尺寸，尽管它也需要位置参数来调整它的大小是不合适的。

为了做到这一点，我们对旋转框对象使用resize方法。

Syntax : spin_box.resize(width, height)

Argument : It takes two integer as argument

Return : It returns None

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, 50, 50)
  
        # setting range to the spin box
        self.spin.setRange(50, 400)
  
        # adding action to the spin box
        self.spin.valueChanged.connect(self.spin_action)
  
    def spin_action(self):
  
        # getting the value of spin box
        value = self.spin.value()
  
        # resizing the spin box
        self.spin.resize(value, 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 ：
