#QML

首先，看了许多例子，都会出现xxxx module not installed！

发的文章也都是抄来抄去，没啥意思，说的让人半懂不懂。

经过反反复复的折腾，终于弄出来了。

描述：QT5.11 win10

1.qml文件并不能完全的隐藏方法。意思就是说你新建了一个工程，引用这个模块，需要

注：第二个文件名称为plugins.qmltypes。因为我截图截错了，下图同。（不再标明）

这4个或者5个文件，如果缺少qml文件(debug编译使用xxxxxxd.dll.release使用xxxxxx.dll)

所以，只有dll和qmldir是不行的。

2.qmldir内容

module com.mycompany.qmlcomponents
plugin QMLPlugin
typeinfo plugins.qmltypes

MyRect 1.0 MyRect.qml

designersupported

3.import路径问题

pro文件的path应该为A处

QML_IMPORT_PATH = E:\QML_Custom_model

main.cpp

engine.addImportPath("E:/QML_Custom_model");

4.plugins.qmltypes

import QtQuick.tooling 1.2

// This file describes the plugin-supplied types contained in the library.
// It is used for QML tooling purposes only.

生成描述文件的方法:

格式:qmlplugindump Arg1 Arg2 Arg3
Arg1 :module名称 Arg2 :module版本 Arg3:插件所在的父路径

1.进入cmd ,cd E:\QML_Custom_model 
2.执行qmlplugindump com.mycompany.qmlcomponents 1.0 E:\QML_Custom_model\plugins.qmltypes

至此，关键部分的讲解都已经说完了。这是别人留下的坑。。。。。。。。。。
