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。
Syntax : spin_box.setBaseSize(width, height)
Argument : It takes two integer argument i.e base and height
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, 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 :
