PyQt5 Combo Box - Skin when pressed

PyQt5 Combo Box - Skin when pressed

To style a QComboBox in PyQt5 when it's pressed, you'll need to use the power of QSS (Qt Style Sheets). This is analogous to CSS for HTML but is used for PyQt/Qt widgets.

To demonstrate, let's say you want to change the background color of the combo box when it's pressed:

  1. Import Necessary Libraries:

    First, set up a basic PyQt5 application:

    import sys from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QComboBox

  2. Create the Main Application Window:

    Set up the main window and layout:

    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']) layout.addWidget(combo) self.setLayout(layout) self.setWindowTitle('Combo Box Styling') self.show()

  3. Style the QComboBox:

    Apply the desired style to the combo box when it's pressed:

    stylesheet = """ QComboBox:pressed { background-color: rgb(200, 200, 200); } """ app = QApplication(sys.argv) app.setStyleSheet(stylesheet) ex = App() sys.exit(app.exec_())

In this example, when the combo box is pressed, its background color changes to a light gray (200, 200, 200). You can customize it further by adding more styles and properties to the stylesheet variable.

Remember, QSS provides a wide array of possibilities for styling, similar to CSS, so you can modify this example to fit your particular needs.
