小编and*_*nes的帖子

我正在尝试使用无框窗口和圆角创建一个简单的Qt UI.从具有QtQuick 2应用程序模板的新项目开始,我的代码如下所示:

main.cpp中

#include <QtGui/QGuiApplication>
#include "qtquick2applicationviewer.h"

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);

    QtQuick2ApplicationViewer viewer;

    viewer.setMainQmlFile(QStringLiteral("qml/qtquick-test/main.qml"));
    viewer.setFlags(Qt::FramelessWindowHint);
    viewer.showExpanded();

    return app.exec();
}

main.qml

import QtQuick 2.0

Rectangle {
    width: 360
    height: 360
    radius: 10
    color: "red"

    Text {
        text: qsTr("Hello World")
        anchors.centerIn: parent
    }
    MouseArea {
        anchors.fill: parent
        onClicked: {
            Qt.quit();
        }
    }
}

这就是结果:

我不想做的是通过使主窗口透明来摆脱白色角落.但是,据我所知,在Qt5中没有办法做到这一点,因为我们没有样式表等,而且我没有使用QtWidget.我应该使用QtWidget吗？

顺便说一句,我是Qt和Qt5的新手.

我正在关注Athena入门指南并尝试解析我自己的Cloudfront日志.但是,字段未被解析.

我用了一个小测试文件,如下:

并使用此SQL创建表:

CREATE EXTERNAL TABLE IF …

我有以下数据:

var data = [
    {
        id: 1,
        name: 'Ed Spencer',
        phoneNumber: '555 1234',
        children: [{
          id: 11,
          name: 'Baz'
        }]
    },
    {
        id: 2,
        name: 'Abe Elias',
        phoneNumber: '666 1234',
        children: [{
          id: 21,
          name: 'Foo'
        },{
          id: 21,
          name: 'Bar'
        }]
    }
];

有没有办法将它加载到某些模型和商店,像这样？

Ext.define('Child', {
    extend: 'Ext.data.Model',
    fields: [
        {name: 'id',    type: 'int'},
        {name: 'user_id',    type: 'int'},
        {name: 'name',  type: 'string'}
    ],

    belongsTo: 'User'
});

Ext.define('User', {
    extend: 'Ext.data.Model',
    fields: [
        {name: 'id',    type: 'int'},
        {name: 'name', …
