PyQt5 – 当鼠标悬停在非可编辑组合框上时，为其行编辑部分设置皮肤

在这篇文章中，我们将看到如何在鼠标悬停在非可编辑组合框的行编辑部分上设置皮肤。行编辑是用来输入和查看项目的部分。皮肤基本上是一个背景图像，它根据行编辑的大小来调整自己。

注意： 当我们在组合框中添加行编辑对象时，它将使组合框可编辑，因此需要使其不可编辑。

做到这一点的步骤：

1.创建一个组合框

2.创建一个QLineEdit对象

3.当鼠标悬停在QlineEdit对象上时，为其设置皮肤

4.使行编辑不可编辑

5.在组合框中添加QLineEdit对象

语法:

# creating line edit object
line_edit = QLineEdit()

# setting skin to line edit when mouse hover over it
line_edit.setStyleSheet("QLineEdit::hover"
                        "{"
                        "border-image : url(skin.png);"
                        "}")

# making it non editable
line_edit.setReadOnly(True)

# adding line edit object to combo box
combo_box.setLineEdit(line_edit)

以下是实施情况

# importing libraries
from PyQt5.QtWidgets 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)
  
        # 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)
  
        # creating line edit object
        line_edit = QLineEdit()
  
        # setting skin to line edit when mouse hover over it
        line_edit.setStyleSheet("QLineEdit::hover"
                                "{"
                                "border-image : url(skin.png);"
                                "}")
  
        # making it non editable
        line_edit.setReadOnly(True)
  
        # adding line edit object to combo box
        self.combo_box.setLineEdit(line_edit)
  
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
window.show()
  
# start the app
sys.exit(App.exec())
