PyQt5 - Adding border to non-editable ComboBox

To add a border to a non-editable QComboBox in PyQt5, you can use the QComboBox's stylesheet. By default, the non-editable QComboBox does not have an input box that's visually similar to other input widgets like QLineEdit. To emphasize the widget's boundary, you can set a border using stylesheets.

Here's a simple example of how to add a border to a non-editable QComboBox:

import sys from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QComboBox class App(QWidget): def __init__(self): super().__init__() self.initUI() def initUI(self): layout = QVBoxLayout() combo = QComboBox(self) combo.addItems(['Option 1', 'Option 2', 'Option 3']) # Setting the combo box to non-editable combo.setEditable(False) # Adding a border using a stylesheet combo.setStyleSheet("QComboBox { border: 2px solid gray; }") layout.addWidget(combo) self.setLayout(layout) self.setWindowTitle('ComboBox Border') self.show() if __name__ == '__main__': app = QApplication(sys.argv) ex = App() sys.exit(app.exec_())

In this example, the setStyleSheet method is used to set a border of 2 pixels with the color gray around the QComboBox. You can adjust the styles (such as border width, style, color, etc.) according to your needs by modifying the stylesheet string.
