Qt:QML:不同目录qml模块的调用

# 简介 #

介绍下不同目录之间的qml模块导入方法，下面是import导入文件夹的语法

import "<DirectoryPath>" [as <Qualifier>]

import不仅能导入本地文件夹也可以导入网络文件

# 示例代码 #

import QtQuick 2.7
    import QtQuick.Controls 1.5
    
    //目录的导入
    import "./qml" as QLL
    
    import "./qml2"
    
    import "https://www.codebee.cc/components"
    
    ApplicationWindow {
        visible: true
        width: 640
        height: 480
        title: qsTr("Hello World")
    
        Label {
            text: qsTr("Hello World")
            anchors.centerIn: parent
        }
    
        QLL.UserDefineRect{
            x:20
            y:20
            width:200
            height: 400
        }
    
        RedRect{
            x:230
            y:20
            width:200
            height: 400
        }
    }

在导入网络文件夹的时候可能会有下面的警告，把qtcreater中的libeay32.dll和ssleay32.dll拷贝到运行目录就可以了（编译qtcreate的编译器和编译当前程序编译器必须是同一个版本的编译器）

# 注意 #

qml文件的文件名首字母必须大写，切记切记
