How does List allocate space using a custom structure in QML?

mirro

property var keyValueList[KeyValue{},KeyValue{}] //Error Code

class KeyValue : public QObject
{
  Q_OBJECT
  Q_PROPERTY(QString key READ getKey WRITE setKey NOTIFY keyChanged)
  Q_PROPERTY(QString value READ getValue WRITE setValue NOTIFY valueChanged)

 public:
  KeyValue(const QString& key, const QString& value, QObject* parent = 0);  

 signals:
  void keyChanged();
  void valueChanged();

 private:
  QString _key;
  QString _value;

  QString getKey() const;
  QString getValue() const;

  void setKey(const QString& key);  
  void setValue(const QString& value);
};
Q_DECLARE_METATYPE(KeyValue*)

qmlRegisterType<KeyValue>("customqml", 1, 0, "KeyValue");

import QtQuick 2.7
import customqml 1.0

Item{
  KeyValue {
    id: idKeyValue 
  }
  property var keyValueList[KeyValue{},KeyValue{}] //***Error Code***
}

I just tested that the specified type needs to be stored in list
Like this,
property list<KeyValue> rects: [
KeyValue{},
KeyValue{}
]

Is there any question you want to ask?

property var keyValueList[KeyValue{},KeyValue{}] //***Error Code***

This is simply invalid syntax in QML. But I don't know what you want to achieve - without more info I can't help more.
