PyQt5 QListWidget – 获取样式表

在这篇文章中，我们将看到如何获得QListWidget的样式表。QListWidget是一个方便的类，它提供了一个基于经典项目的列表视图，用于添加和删除项目。QListWidget使用一个内部模型来管理列表中的每个QListWidgetItem。样式表是用于使外观更好的属性，即通过创建自定义设计。它可以在setStyleSheet方法的帮助下被设置。它可以在setStyleSheet方法的帮助下进行设置。

为了做到这一点，我们将使用列表部件对象的styleSheet方法。

语法： list_widget.styleSheet()

参数： 它需要参数

返回： 它返回字符串

下面是样式表的示例代码

QListWidget
{
border : 2px solid black;
background : lightgreen;
}
QListWidget QScrollBar
{
background : lightblue;
}
 QListView::item:selected
{
border : 2px solid black;
background : green;
}

以下是实施情况

# 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, 500, 400)
 
        # calling method
        self.UiComponents()
 
        # showing all the widgets
        self.show()
 
 
 
    # method for components
    def UiComponents(self):
 
        # creating a QListWidget
        list_widget = QListWidget(self)
 
        # setting geometry to it
        list_widget.setGeometry(50, 70, 150, 80)
 
        # list widget items
        item1 = QListWidgetItem("PyQt5 Geeks for Geeks")
        item2 = QListWidgetItem("B")
        item3 = QListWidgetItem("C")
        item4 = QListWidgetItem("D")
 
        # adding items to the list widget
        list_widget.addItem(item1)
        list_widget.addItem(item2)
        list_widget.addItem(item3)
        list_widget.addItem(item4)
 
        # setting style sheet
        list_widget.setStyleSheet("QListWidget"
                                  "{"
                                  "border : 2px solid black;"
                                  "background : lightgreen;"
                                  "}"
                                  "QListWidget QScrollBar"
                                  "{"
                                  "background : lightblue;"
                                  "}"
                                  "QListView::item:selected"
                                  "{"
                                  "border : 2px solid black;"
                                  "background : green;"
                                  "}"
                                  )
 
        # creating a label
        label = QLabel("GeeksforGeeks", self)
 
        # setting geometry to the label
        label.setGeometry(230, 80, 280, 80)
 
        # making label multi line
        label.setWordWrap(True)
 
        # getting style sheet
        value = list_widget.styleSheet()
 
        # setting text to the label
        label.setText(value)
 
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
