我正在开发一款用于接触式阅读的应用程序。在联系人添加页面中,我创建了一些文本字段,如名字 n 姓氏、电话号码等。我还创建了一个 ActionItem 来保存或创建联系人。像这样
acceptAction: ActionItem {
title: (_contactRead.contactEditor.mode == ContactEditor.CreateMode ? qsTr ("Create" ) : qsTr ("Save"))
onTriggered: {
_contactRead.contactEditor.saveContact()
navigationPane.pop()
}
}
我想在我们点击保存或创建联系人时显示弹出窗口(对话框或 toast )。我尝试在 onTriggered 中添加 open(),但对创建对话框的方式和位置感到困惑。
请帮帮我....
最佳答案
使用 --> alert(tr("联系人已保存"));
引用下面的例子
------------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;
}
