Qt属性表QtProperty添加可选combox下拉框，添加属性列表

Qt属性表QtProperty添加可选下拉框属性列表

项目中，控件属性要求可以选择，就想着怎么做出combox的效果，最后在里面找到了QtVariantPropertyManager::enumTypeId(),这个属性，非常完美

效果图

代码

	m_pVarManager = new QtVariantPropertyManager(ui->propertyTree);
    m_pVarFactory = new QtVariantEditorFactory(ui->propertyTree);
    
    connect(m_pVarManager, &QtVariantPropertyManager::valueChanged, this, &MainWindow::variantPropertyValueChanged);
 
    QtProperty *groupItem = m_pVarManager->addProperty(QtVariantPropertyManager::groupTypeId(),QStringLiteral("Group1"));
 
    QtVariantProperty *item = m_pVarManager->addProperty(QVariant::Int, QStringLiteral("Int: "));

	item = m_pVarManager->addProperty(QtVariantPropertyManager::enumTypeId(), QLatin1String("事件组"));
    QStringList enumNames;
    enumNames << "事件1" << "事件2" << "事件3";
    item ->setAttribute(QLatin1String("enumNames"), enumNames);
    item ->setValue(1);
    groupItem ->addSubProperty(item );
    ui.widget->addProperty(groupItem);
