PyQt5 QSpinBox – 为行编辑部分添加背景色

在这篇文章中，我们将看到如何为旋转盒子的行编辑部分设置背景色，行编辑部分是旋转盒子的文本部分，在这里我们可以看到文本并输入用户值。

为了 做到这一点，我们必须做以下工作 –

1.创建一个旋钮箱

2.获取旋钮箱的行编辑对象

3.向该行编辑对象添加顺序

语法:

# get the line edit object
line = self.spin_box.lineEdit()

# setting background color to the line edit object
line.setStyleSheet("QLineEdit"
                   "{"
                   "background-color : yellow;"
                   "}")

以下是实现方法

# 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")

        # get the line edit object
        line = self.spin.lineEdit()

        # setting background color to the line edit object
        line.setStyleSheet("QLineEdit"
                           "{"
                           "background-color : yellow;"
                           "}")



# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

输出：
