PyQt5 - Background image to non-editable ComboBox when OFF state

To set a background image to a non-editable QComboBox in PyQt5 when it's in an "OFF" state, you can use the Qt Style Sheet (QSS) mechanism to style the widget.

Let's go step by step:

  1. Design your ComboBox.
  2. Create a logic to determine the "OFF" state.
  3. Use Qt Style Sheets to set a background image when the ComboBox is in the "OFF" state.

Here's a code example to demonstrate:

import sys from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QComboBox class AppDemo(QWidget): def __init__(self): super().__init__() self.setWindowTitle('ComboBox Background Image') layout = QVBoxLayout() self.comboBox = QComboBox(self) self.comboBox.addItems(['Option 1', 'Option 2', 'OFF', 'Option 3']) self.comboBox.currentIndexChanged.connect(self.on_combobox_change) layout.addWidget(self.comboBox) self.setLayout(layout) self.show() def on_combobox_change(self, index): if self.comboBox.currentText() == 'OFF': # Apply the style sheet when in "OFF" state self.comboBox.setStyleSheet(""" QComboBox { background-image: url('path_to_your_image.jpg'); } """) else: # Clear the style sheet for other states self.comboBox.setStyleSheet('') app = QApplication(sys.argv) demo = AppDemo() sys.exit(app.exec_())

Replace 'path_to_your_image.jpg' with the path to your desired background image. Whenever the combobox changes its value, it checks if the selected value is "OFF". If it is, it sets the background image; otherwise, it clears the style sheet.

Note: You might need to adjust the style sheet further depending on the exact look and feel you're aiming for. This example simply sets a background image, but other properties might be needed for precise styling.
