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 );
