If you want the QComboBox control to be displayed continuously during the program’s runtime, you can use the following method:

  1. Set the initial visibility of the QComboBox control to be visible in the constructor of the window.
self.comboBox.setVisible(True)
  1. Set the display policy of the QComboBox control to AlwaysShow so that the QComboBox control will always be displayed regardless of whether there are drop-down options or not.
self.comboBox.view().setShowAlways(True)
  1. Set the minimum width of the QComboBox control to 0 to ensure that the control can still be displayed even when there are no drop-down options.
self.comboBox.setMinimumWidth(0)

By using the above method, you can ensure that the QComboBox widget is always displayed on the program interface, regardless of whether there are any dropdown options.
