QComboBox - How to set hint text on combo box

Question

The application GUI I working requires a combo box for user to select item. When the application starts, the combo box will show a hint text something like \"Please select\"

Answer 1

There is an elegant solution if the QComboBox is editable:

myQComboBox->lineEdit()->setPlaceHolderText("Please select");

QComboBoxes that are not editable do not have QLineEdits in them, so this would not work on those.
