Detailed Description▲
This class defines the standard interface that proxy models must use to be able to interoperate correctly with other model/view components. It is not supposed to be instantiated directly.
All standard proxy models are derived from the https:// class. If you need to create a new proxy model class, it is usually better to subclass an existing class that provides the closest behavior to the one you want to provide.
Proxy models that filter or sort items of data from a source model should be created by using or subclassing https://.
To subclass https://, you need to implement https://() and https://(). The https://() and https://() functions only need to be reimplemented if you need a behavior different from the default behavior.
If the source model is deleted or no source model is specified, the proxy model operates on a empty placeholder model.

Property Documentation▲
[bindable] sourceModel : QAbstractItemModel*▲
This property supports https:// bindings.
This property holds the source model of this proxy model.
Member Function Documentation▲
[explicit] QAbstractProxyModel::QAbstractProxyModel(QObject *parent = nullptr)▲
Constructs a proxy model with the given parent.
[virtual] QAbstractProxyModel::~QAbstractProxyModel()▲
Destroys the proxy model.
[override virtual] QModelIndex QAbstractProxyModel::buddy(const QModelIndex &index) const▲
Reimplements: https://.
[override virtual, since 5.4] bool QAbstractProxyModel::canDropMimeData(const QMimeData *data, Qt::DropAction action, int row, int column, const QModelIndex &parent) const▲
Reimplements: https://.
This function was introduced in Qt 5.4.
[override virtual] bool QAbstractProxyModel::canFetchMore(const QModelIndex &parent) const▲
Reimplements: https://.
[override virtual, since 6.0] bool QAbstractProxyModel::clearItemData(const QModelIndex &index)▲
Reimplements: https://.
This function was introduced in Qt 6.0.
[protected, since 6.2] QModelIndex QAbstractProxyModel::createSourceIndex(int row, int col, void *internalPtr) const▲
Equivalent to calling createIndex on the source model.
This method is useful if your proxy model wants to maintain the parent-child relationship of items in the source model. When reimplementing https://(), you can call this method to create an index for row row and column col of the source model.
A typical use would be to save the internal pointer coming from the source model in the proxy index when reimplementing https://() and use the same internal pointer as internalPtr to recover the original source index when reimplementing https://().
This function was introduced in Qt 6.2.
[override virtual] QVariant QAbstractProxyModel::data(const QModelIndex &proxyIndex, int role = Qt::DisplayRole) const▲
[override virtual, since 5.4] bool QAbstractProxyModel::dropMimeData(const QMimeData *data, Qt::DropAction action, int row, int column, const QModelIndex &parent)▲
Reimplements: https://.
This function was introduced in Qt 5.4.
[override virtual] void QAbstractProxyModel::fetchMore(const QModelIndex &parent)▲
Reimplements: https://.
[override virtual] Qt::ItemFlags QAbstractProxyModel::flags(const QModelIndex &index) const▲
Reimplements: https://.

[virtual] void QAbstractProxyModel::setSourceModel(QAbstractItemModel *sourceModel)▲
Sets the given sourceModel to be processed by the proxy model.
Subclasses should call https://() at the beginning of the method, disconnect from the old model, call this method, connect to the new model, and call https://().
Setter function for property https://.
