PyQt5 QSpinBox – 设置基本尺寸

在本文中,我们将看到如何设置旋转框的基本尺寸,如果旋转框定义了sizeIncrement ,则基本尺寸用于计算合适的旋转框尺寸。默认情况下,对于新创建的旋转框,此属性包含宽度和高度为零的大小。

以下是当主窗口变大时获取新旋转框大小的公式。

width = baseSize().width() + i * sizeIncrement().width()
height = baseSize().height() + j * sizeIncrement().height()

Here i, j are the size increment in the main window

为了设置基本大小,我们使用 setBaseSize 方法。

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")
  
        # setting base size
        self.spin.setBaseSize(250, 40)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
