Some QComboBox and custom QValidator background

[frankiefrank]

First of all thank you for your time and attention, and for bringing up the relevant documentation.

I'm sorry but even after reading about the different types of signals emitted from the lineEdit control I can't "guess" the behavior of an editable QComboBox just because it has a lineEdit member. For example, where does it say that validation is even called upon leaving focus of the combo's lineEdit?

I don't expect the documentation to answer "every question" for "every case". I stand by what I said that the documentation about the integration of a validator and a combox is almost not there (unless you know how the combo box wraps the signals emitted from its lineEdit members).

I put a breakpoint in my validate method to see if it's called at any point during my UI/programmatic interaction. I'm not seeing any calls so I'm guessing something in my wiring is wrong.

This piece of documentation:

"Note that if there is a validator set on the line edit, the returnPressed()/editingFinished() signals will only be emitted if the validator returns QValidator::Acceptable."

still leaves me wondering why I'm not seeing the call.

For example, where does it say that validation is even called upon leaving focus of the combo's lineEdit?

Here (QLineEdit):

When editing is finished, either because the line edit lost focus or Return/Enter is pressed the editingFinished() signal is emitted.

And since the validator is applied during text input, and because finishing the text input through focus change is part of the input, the validator should be called as result of focus leave.

I put a breakpoint in my validate method to see if it's called at any point during my UI/programmatic interaction. I'm not seeing any calls so I'm guessing something in my wiring is wrong.

Ok, that is the right way to do it.
Hmm...
Can you post the code where you set your validator?
