【中文标题】如何添加警报声音（音频）？【英文标题】：How do I add an alarm sound(Audio)? 【发布时间】：2022-01-23 03:30:17 【问题描述】：我正在用QML写一个闹钟，我需要在闹钟日期和时间到达系统时添加闹钟声音（一般在闹钟正常运行时触发闹钟声音）。我该怎么做？
这里有闹钟（包括添加的）：
AlarmModel.qml
import QtQuick 2.11
import QtQuick.Controls 2.4
import QtQuick.Layouts 1.11
import QtQuick.Window 2.11
// Populate the model with some sample data.
ListModel
id: alarmModel
ListElement
hour: 6
minute: 1
day: 3
month: 8
year: 2021
activated: true
label: "Wake up"
repeat: true
daysToRepeat: [
ListElement dayOfWeek: 0; repeat: false ,
ListElement dayOfWeek: 1; repeat: false ,
ListElement dayOfWeek: 2; repeat: false ,
ListElement dayOfWeek: 3; repeat: false ,
ListElement dayOfWeek: 4; repeat: false ,
ListElement dayOfWeek: 5; repeat: false ,
ListElement dayOfWeek: 6; repeat: false
]
ListElement
hour: 6
minute: 0
day: 3
month: 8
year: 2021
activated: true
label: "Wake up"
repeat: true
daysToRepeat: [
ListElement dayOfWeek: 0; repeat: true ,
ListElement dayOfWeek: 1; repeat: true ,
ListElement dayOfWeek: 2; repeat: true ,
ListElement dayOfWeek: 3; repeat: true ,
ListElement dayOfWeek: 4; repeat: true ,
ListElement dayOfWeek: 5; repeat: false ,
ListElement dayOfWeek: 6; repeat: false
]
ListElement
hour: 7
minute: 0
day: 3
month: 8
year: 2021
activated: false
label: "Exercise"
repeat: true
daysToRepeat: [
ListElement dayOfWeek: 0; repeat: true ,
ListElement dayOfWeek: 1; repeat: true ,
ListElement dayOfWeek: 2; repeat: true ,
ListElement dayOfWeek: 3; repeat: true ,
ListElement dayOfWeek: 4; repeat: true ,
ListElement dayOfWeek: 5; repeat: true ,
ListElement dayOfWeek: 6; repeat: true
]
ListElement
hour: 5
minute: 15
day: 1
month: 9
year: 2021
activated: true
label: ""
repeat: false
daysToRepeat: [
ListElement dayOfWeek: 0; repeat: false ,
ListElement dayOfWeek: 1; repeat: false ,
ListElement dayOfWeek: 2; repeat: false ,
ListElement dayOfWeek: 3; repeat: false ,
ListElement dayOfWeek: 4; repeat: false ,
ListElement dayOfWeek: 5; repeat: false ,
ListElement dayOfWeek: 6; repeat: false
]
ListElement
hour: 5
minute: 45
day: 3
month: 4
year: 2021
activated: false
label: ""
repeat: false
daysToRepeat: [
ListElement dayOfWeek: 0; repeat: false ,
ListElement dayOfWeek: 1; repeat: false ,
ListElement dayOfWeek: 2; repeat: false ,
ListElement dayOfWeek: 3; repeat: false ,
ListElement dayOfWeek: 4; repeat: false ,
ListElement dayOfWeek: 5; repeat: false ,
ListElement dayOfWeek: 6; repeat: false
]
function sortModel()
for(var i=0; i<count; i++)
for(var j=0; j<count; j++)
if(get(i).year < get(j).year)
move(i,j,1)
else if(get(i).year === get(j).year && get(i).month < get(j).month)
move(i,j,1)
else if(get(i).year === get(j).year && get(i).month === get(j).month && get(i).day < get(j).day)
move(i,j,1)
else if(get(i).year === get(j).year && get(i).month === get(j).month && get(i).day === get(j).day && get(i).hour < get(j).hour)
move(i,j,1)
else if(get(i).year === get(j).year && get(i).month === get(j).month && get(i).day === get(j).day && get(i).hour === get(j).hour && get(i).minute < get(j).minute)
move(i,j,1)
Component.onCompleted: sortModel()
这里增加了一个闹钟：
AlarmDialog.qml
import QtQuick 2.11
import QtQuick.Controls 2.4
import QtQuick.Layouts 1.11
import QtQuick.Window 2.11
Dialog
id: alarmDialog
title: "Add new alarm"
modal: true
standardButtons: DialogButtonBox.Ok | DialogButtonBox.Cancel
property AlarmModel alarmModel
function formatNumber(number)
return number < 10 && number >= 0 ? "0" + number : number.toString()
onAccepted:
alarmModel.insert(alarmModel.count,
"hour": hoursTumbler.currentIndex,
"minute": minutesTumbler.currentIndex,
"day": dayTumbler.currentIndex + 1,
"month": monthTumbler.currentIndex + 1,
"year": yearTumbler.years[yearTumbler.currentIndex],
"activated": true,
"label": "",
"repeat": false,
"daysToRepeat": [
"dayOfWeek": 0, "repeat": false ,
"dayOfWeek": 1, "repeat": false ,
"dayOfWeek": 2, "repeat": false ,
"dayOfWeek": 3, "repeat": false ,
"dayOfWeek": 4, "repeat": false ,
"dayOfWeek": 5, "repeat": false ,
"dayOfWeek": 6, "repeat": false
],
)
alarmModel.sortModel()

Tumbler
id: dayTumbler
function updateModel()
// Populate the model with days of the month. For example: [0, ..., 30]
var previousIndex = dayTumbler.currentIndex
var array = []
var newDays = datePicker.days[monthTumbler.currentIndex]
for (var i = 1; i <= newDays; ++i)
array.push(i)
dayTumbler.model = array
dayTumbler.currentIndex = Math.min(newDays - 1, previousIndex)
Component.onCompleted: updateModel()

readonly property var years: (function()
var currentYear = new Date().getFullYear()
return [0, 1, 2, 3].map(function(value) return value + currentYear ; )
)()
model: years

【问题讨论】：
【参考方案1】：我真的不打算回答，但是“添加评论”链接似乎坏了（可能是我的旧 WinXP 浏览器）。 你看过“声音”QML 类型吗？ (https://doc.qt.io/qt-5/qml-qtaudioengine-sound.html) 还是 SoundEffect QML 类型？ (https://doc.qt.io/qt-5/qml-qtmultimedia-soundeffect.html#details)。 他们只需要您提供一个 .wav 文件。
