如何添加报警声音(音频)

Question

我正在QML中编写一个闹钟，当闹钟日期和时间到达系统时，我需要添加一个闹钟声音(通常，闹钟正常工作时会触发闹钟声音(。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.Window 2.11

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()
}  
onRejected: alarmDialog.close()

contentItem: RowLayout {
RowLayout {

Tumbler {

model: 24
delegate: TumblerDelegate {

}
}

readonly property var days: [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]
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()
delegate: TumblerDelegate {

}
}
Tumbler {

onCurrentIndexChanged: dayTumbler.updateModel()
model: 12
delegate: TumblerDelegate {
text: window.locale.standaloneMonthName(modelData, Locale.ShortFormat)
}
}
Tumbler {
id: yearTumbler
// This array is populated with the next three years. For example: [2021, 2022, 2023, 2024]
readonly property var years: (function() {
var currentYear = new Date().getFullYear()
return [0, 1, 2, 3].map(function(value) { return value + currentYear ; })
})()
model: years
delegate: TumblerDelegate {
text: formatNumber(modelData)
}
}
}
}
}

我真的不想回答，但；添加评论"；链接似乎断了(可能是我的旧WinXP浏览器(。你看过"；声音"；QML类型？(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)。他们只需要你提供一个.wav文件。
