QtApplets-自定义控件-6-属性研究
接上篇，我们最后的那个升华了的小问题，如何使用自定义的数据类型作为我们自定义控件的属性呢。看帮助文档是支持的，但是要什么样子的自定义数据类型，这里没有写呀。这里我没有搞定，后面的内容不用看了。
The property name and type and the READ function are required. The type can be any type supported by QVariant, or it can be a user-defined type. The other items are optional, but a WRITE function is common. The attributes default to true except USER, which defaults to false.
For example:
Q_PROPERTY(QString title READ title WRITE setTitle USER true)
For more details about how to use this macro, and a more detailed example of its use, see the discussion on Qt’s Property System.

提升一下，给用户来个选择咋样？
☞ 源码
关键字： Q_PROPERTY、属性、自定义、设置、获取

目前状态呢，我已经实现一个自定义的类，代码如下
testrect.h
#ifndef TESTRECT_H #define TESTRECT_H #include <QObject> #include <QSharedDataPointer> #include <QWidget> class TestRectData; class TestRect : public QWidget { Q_OBJECT Q_PROPERTY(int testX READ getTestX WRITE setTestX) public: explicit TestRect(QWidget *parent = nullptr); TestRect(const TestRect &); TestRect &operator=(const TestRect &); ~TestRect(); int getTestX(); void setTestX(int temp); signals: private: QSharedDataPointer<TestRectData> data; private: int mTestX = 0; }; #endif // TESTRECT_H
testrect.cpp
#include "testrect.h" class TestRectData : public QSharedData { public: }; TestRect::TestRect(QWidget *parent) : QWidget(parent), data(new TestRectData) { } TestRect::TestRect(const TestRect &rhs) : data(rhs.data) { } TestRect &TestRect::operator=(const TestRect &rhs) { if (this != &rhs) data.operator=(rhs.data); return *this; } TestRect::~TestRect() { } int TestRect::getTestX() { return mTestX; } void TestRect::setTestX(int temp) { }
