PyQt5 QSpinBox – 获得最高利润
在本文中,我们将看到如何获得旋转框的上边距,默认情况下它设置为零,尽管我们可以使用setTop
方法对旋转框的边距对象进行更改。
为了做到这一点,我们使用margin.top方法。
Syntax : margin.top()
Here margin is the QMargin object of the spin box
Argument : It takes no argument
Return : It returns integer
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(0, 999999)
# setting prefix to spin
self.spin.setPrefix("Prefix ")
# setting suffix to spin
self.spin.setSuffix(" Suffix")
# creating label
label = QLabel(self)
# setting geometry to the label
label.setGeometry(100, 200, 200, 70)
# making it multi line label
label.setWordWrap(True)
# setting content margins
self.spin.setContentsMargins(1, 2, 2, 1)
# getting content margins
margin = self.spin.contentsMargins()
# getting top margin value
top = margin.top()
# setting text to the label
label.setText("Top Margin = " + str(top))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
window.spin.setFocus()
# start the app
sys.exit(App.exec())
输出 :
