QcomboBox autoCompletion

[Lele]

Hi all,
hoping this won't be a trivial question, I'd like to know if it's possible to prevent the user from entering invalid data when filling a QComboBox editable with autoCompletion.
I mean, I have a list of Countries and to help the user I set the combo editable, but I don't want that user could write and leave invalid data (such as Germanysd...)
I can check after but I'd like to avoid any invalid data to appear.
thanks in advance

bye

Write a validator and set it with QComboBox::setValidator().

thanks for replying,
I can't figure it out how to write the QValidator::validate to accomplich my requirements,
maybe I could check when user lost focus from the combo and put the closest string from the possible items.
thanks again

Don't give up. It's not so complicated!

QComboBox uses a QStringListModel. Pass a QStringList fetched from the model to the validator to validate against. Here's a pseudo algo suggestion for QValidator::validate()

if stringlist contains input
	return Acceptable
else if input is empty or any string in the stringlist starts with input
	return Intermediate
else
	return Invalid

if stringlist contains input
	return Acceptable
else if input is empty or any string in the stringlist starts with input
	return Intermediate
else
	return Invalid
