Combobox Signals

[jpn]

There is no signal called returnPressed that is emitted by QComboBox.

You may, however, connect to combo box's internal line edit:

connect( comboBox_3->lineEdit(), SIGNAL( returnPressed() ), this, SLOT( readSData() ) );

connect( comboBox_3->lineEdit(), SIGNAL( returnPressed() ), this, SLOT( readSData() ) );
