How to select a specific text entry (or add it if does not exist) in a combo box

The following method acts on a combo box searching for a specified text string and:
* if the string is present select it
* if the string is not present add it to the combo box model

In the following piece of code myText is the QString searched for and combo is a reference to the combo box.

bool found = false;
for( int i = 0; i < combo->count() && ! found ; i++ )
if( combo->itemText( i ) == myText ){
combo->setCurrentIndex( i );
found = true;
}

if( ! found ){
int index = combo->count();
combo->addItem( myText );

combo->setCurrentIndex( index );
