PyQt5组合框 按压时的皮肤

在这篇文章中，我们将看到如何在组合框被按下时为其设置皮肤。皮肤基本上是背景图片，但皮肤会根据组合框的大小来调整其大小。只有当组合框被按下时，皮肤才会出现。

为了做到这一点，我们必须改变组合框的样式表代码，下面是样式表代码

QComboBox::pressed
{
border-image : url(image.png);
}

下面是实现方法

# 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 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)

        # setting style sheet of combo box
        # adding skin to the combo box when it get pressed
        self.combo_box.setStyleSheet("QComboBox::pressed"
                                     "{"
                                     "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())
