[Development] QML and QAbstractListModel

[Nils Jeisecke]

Hi,

what about adding a new Quick item for "enhanced QAbstractItemModel access".

ListModelAdapter {
  id: myModelAdapter
  sourceModel: myModel
}

ListView {
  model: myModelAdapter.sourceModel
  delegate: Text {
    MouseArea {
      onClicked: console.log(myModelAdapter.data(model.index, "myRole")
    }
  }
}

Something like this:

#ifndef QQUICKLISTMODELADAPTER_H
#define QQUICKLISTMODELADAPTER_H

#include <QObject>
#include <QAbstractItemModel>

class QQuickListModelAdapter : public QObject
{
  Q_OBJECT
  Q_PROPERTY(QAbstractItemModel *sourceModel READ sourceModel WRITE
setSourceModel NOTIFY sourceModelChanged)
  Q_PROPERTY(int count READ count NOTIFY countChanged)

public:
  explicit QQuickListModelAdapter(QObject *parent = 0);

  void setSourceModel(QAbstractItemModel *model);
  QAbstractItemModel *sourceModel() const;

  Q_INVOKABLE QVariant data(int row, const QString &role);
  Q_INVOKABLE bool setData(row, const QString &role, const QVariant &value);
  /* other useful methods */

signals:
  void sourceModelChanged();
};

#endif // QLISTMODELADAPTER_H
