QT QML中是否有一个简单的功能,可以将hs:mm:ss:zzz格式的毫秒数转换为用户可读时间?我找到了https://doc.qt.io/qt-5/qml-qtqml-date.html文档,但我不太了解如何使用它。到目前为止,这是我的代码,但仅显示秒和millisenconds。
import QtQuick 2.8
import QtQuick.Controls 2.1
Rectangle {
id: mapItem
anchors.fill: parent
property int count: 0
Timer {
id: timer
interval: 100
running: true
repeat: true
onTriggered: count += 1
}
Text {
text: (count / 10).toFixed(3)
font.pixelSize: 20
font.bold: true
font.family: "Eurostile"}
}
答案 0 :(得分:0)
在Felgo Web Editor上进行了测试,我已按预期设置了计数器的格式,请参阅下文!;
Schema::create('replies', function (Blueprint $table)
{
$table->bigIncrements('id');
$table->unsignedBigInteger('user_id'); // <-----------
$table->unsignedBigInteger('thread_id'); // <-----------
$table->text('body');
$table->timestamps();
});
请记住,如果您要设置日期格式,则可以将import Felgo 3.0
import QtQuick 2.5
App {
id: app
Rectangle {
id: mapItem
property int count: 0
Timer {
id: timer
interval: 10 // i set to 10 for testing for faster results, but worked on 100 also
running: true
repeat: true
onTriggered: time.text = new Date(mapItem.count += 1).toLocaleTimeString(Qt.locale(), "hh " + "mm " + "ss " + "zzz") // you can change the formatting as you please
}
Text {
id: time
font.bold: true
font.family: "Eurostile"
}
}
}
替换为toLocaleTimeString
或对每个用例而言最合适的内容。
更新!如果您要实时计数,那么您可能还希望将toLocaleDateString
更改为count += 1
并加上间隔,除非计时器不是实时秒数
希望这会有所帮助!
