PyQt5 - 将背景图像设置为不可编辑的组合框
在本文中,我们将了解如何在组合框不可编辑时将背景图像设置为组合框。默认情况下,组合框没有图像,尽管我们可以为其设置图像。仅当组合框处于不可编辑状态时才会出现背景图像。普通组合框可以在 setEditable 方法的帮助下进行编辑。
为此,我们必须更改与组合框关联的样式表,下面是样式表代码
QComboBox::!editable
{
background-image : url(image.png);
border : 2px solid black;
}
下面是实现
Python3
# 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 the combo box
# adding background image to the combo box it is non-editable
self.combo_box.setStyleSheet("QComboBox::! editable"
"{"
"background-image : url(logo.png);"
"border : 2px 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 :
