PyQt5组合框 向下箭头的背景图片
在这篇文章中,我们将看到如何为组合框的向下箭头添加背景图片。下箭头是组合框的一个组件,它作为一个按钮用于显示列表视图。下面是向下箭头的背景图像的表现形式
为了做到这一点,我们必须改变与组合框相关的样式表,下面是样式表的代码
QComboBox::down-arrow
{
background-image : url(image.png);
}
下面是实现的过程
# 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)
# making combo box editable
self.combo_box.setEditable(True)
# 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 background image to the down arrow
self.combo_box.setStyleSheet("QComboBox::down-arrow"
"{"
"background-image : url(logo.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())
输出:
