Checkbox Setfocus

[afro_cv]

I need an example, as moves to a qlineedit after i presses a checkbox:
something like that


ui->txtGarg - QLineEdit

void protocolonutri::on_cboOthersGarg_toggled(bool checked)
{
ui->txtGarg->setEnabled(checked);
if (!checked)
ui->txtGarg->setText("");

else
ui->txtGarg->setFocus();
}
