PyQt5 – 当鼠标悬停时为组合框的视图部分设置皮肤

在这篇文章中,我们将看到如何在鼠标悬停在组合框上时为其视图部分设置皮肤。视图部分是显示所有项目的地方,当组合框被按下时,视图部分显示它自己。setView和view方法用于设置和获取组合框的视图对象,默认组合框有QListView类型的对象。

为了做到这一点,我们必须改变与组合框相关的样式表代码,下面是样式表代码

QListView::hover
{
border-image : url(image.png);
}

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, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for widgets
    def UiComponents(self):
        # creating a check-able combo box object
        self.combo_box = QComboBox(self)
  
        # setting geometry of combo box
        self.combo_box.setGeometry(200, 150, 200, 80)
  
        # making combo box editable
        # self.combo_box.setEditable(True)
  
        # geek list
        geek_list = ["Sayian", "Super Sayian", "Super Sayian 2", "Super Sayian B"]
  
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
  
        # setting style sheet
        # adding skin to list view when mouse hover over it
        self.combo_box.setStyleSheet("QListView::hover"
                                     "{"
                                     "border-image : url(image.png);"
                                     "border : 1px solid black;"
                                     "}")
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
window.show()
  
# start the app
sys.exit(App.exec())
