我正在开发一个用于联系人阅读的应用程序。在联系人添加页面中,我创建了一些文本字段,如名字、姓氏、电话号码等。我还创建了一个ActionItem来保存或创建联系人。像这个

acceptAction: ActionItem {
        title: (_contactRead.contactEditor.mode == ContactEditor.CreateMode ? qsTr ("Create" ) : qsTr ("Save"))
        onTriggered: {
            _contactRead.contactEditor.saveContact()
            navigationPane.pop()
        }
    }

当我们点击保存或创建联系人时,我想显示弹出窗口(对话框或toast)。我试图在onTriggered中添加open(),但对如何以及在哪里创建对话框感到困惑。

请帮帮我。。。。

使用-->警报(tr("已保存联系人");

参考以下样本

-----------qml--------------

 Button {
            horizontalAlignment: HorizontalAlignment.Center
            text: qsTr("Update")
            onClicked: {
                _app.updateRecord(idUpdateTextField.text, firstNameUpdateTextField.text, lastNameUpdateTextField.text);
            }
        }

-----------------cpp文件------------------

bool App::updateRecord(const QString &customerID, const QString &firstName, const QString &lastName)
{

    bool intConversionGood = false;
    const int customerIDKey = customerID.toInt(&intConversionGood);
    if (!intConversionGood) {
        alert(tr("You must provide valid integer key."));
        return false;
    }

    QSqlDatabase database = QSqlDatabase::database();
    QSqlQuery query(database);
    const QString sqlCommand = "UPDATE customers "
                               "    SET firstName = :firstName, lastName = :lastName"
                               "    WHERE customerID = :customerID";
    query.prepare(sqlCommand);
    query.bindValue(":firstName", firstName);
    query.bindValue(":lastName", lastName);
    query.bindValue(":customerID", customerIDKey);

    bool updated = false;
    if (query.exec()) {
        if (query.numRowsAffected() > 0) {
            alert(tr("Customer with id=%1 was updated.").arg(customerID));
            updated = true;
        } else {
            alert(tr("Customer with id=%1 was not found.").arg(customerID));
        }
    } else {
        alert(tr("SQL error: %1").arg(query.lastError().text()));
    }

    database.close();
    return updated;
}

对于此处的示例应用程序
