<![CDATA[How to update or create new model of QCompleter?]]>I'm try code:

completeT = new QCompleter( listString, this );
	completeT ->setCaseSensitivity( Qt::CaseInsensitive );
	completeT ->setCompletionMode( QCompleter::PopupCompletion );
	completeT ->setFilterMode( Qt::MatchContains );
	ui->txt_lineEdit->setCompleter( completeT );

and I update by code:

completeT ->setModel( new QStringListModel( listCompleteT, this) );

and I have error:57c37b60-d518-4c98-9463-988fad83af10-image.png

How to update QStringList in my QCompleter?
if new QCompleter() that increase memory and optimal?

Update the content of the model you use for the completer. No need to recreate stuff again and again.
