QComboBox doesn't remember text if it's been set before the first addItem().

This can be seen in the following example :

#include <QComboBox>
#include <QApplication>
#include <QLineEdit>
int main(int argc, char **argv) {
QApplication app(argc, argv);
QComboBox box;
box.setEditable(true);
box.setEditText ( "My custom choice 1 vanishes" );
box.addItem("Standard choice 1");
box.addItem("Standard choice 2");
// box.setEditText ( "My custom choice 2 this stays" );
box.show();
return app.exec();
}
