如何调用QCombobox的linedit的KeyPressEvent（QKeyEvent *）？

Question

I have a QComboBox , which is editable, I implemented the keyPressEvent(QKeyEvent *) method, but it does not seem to fire this method.

I can think of the only reason this happens is that whatever editing that occurs is actually happening in lineEdit object and We should implement keyPressEvent(QKeyEvent *) of line Edit . How can I achieve this?

Answer 1

You have two options:

1. Install an event filter on the lineEdit widget.

2. Use setLineEdit to replace the existing widget with your own subclass that reimplements the event handler.
