Member Function Documentation
[signal] void UtilityTraceFunctionBarrierListModel::errorOccurred (Esri::ArcGISRuntime::Error error)
Signal emitted when an error occurs.
- error - Details about the error.
[signal] void UtilityTraceFunctionBarrierListModel::itemAdded (int index)
Signal emitted when an item is added to the list.
index is the index of the added item.
This function was introduced in Esri::ArcGISRuntime 100.15.
[signal] void UtilityTraceFunctionBarrierListModel::itemRemoved (int index)
Signal emitted when an item is removed from the list.
index is the index of the removed item.
This function was introduced in Esri::ArcGISRuntime 100.15.
[override virtual] UtilityTraceFunctionBarrierListModel::~UtilityTraceFunctionBarrierListModel ()
Destructor.
void UtilityTraceFunctionBarrierListModel::append(Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *utilityTraceFunctionBarrier )
Appends the utilityTraceFunctionBarrier to the list model.
[override virtual] Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *UtilityTraceFunctionBarrierListModel::at(int index) const
Returns the UtilityTraceFunctionBarrier at the specified index.
void UtilityTraceFunctionBarrierListModel::clear()
Removes all UtilityTraceFunctionBarrier instances from the list model.
List models do not take ownership of the objects they contain. Therefore, removing or clearing objects from the list model will not delete those objects. An RAII technique should be used to ensure that memory is properly deallocated.
bool UtilityTraceFunctionBarrierListModel::contains(Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *utilityTraceFunctionBarrier ) const
Returns whether the provided utilityTraceFunctionBarrier is in the list model.
[override virtual] QVariant UtilityTraceFunctionBarrierListModel::data(const QModelIndex &index, int role = Qt::DisplayRole) const
Reimplements: QAbstractItemModel::data(const QModelIndex &index, int role) const.
Returns the data stored under the given role for the UtilityTraceFunctionBarrier referred to by the index.
- index - The index in the model for which to return data.
- role - The role for which to return data.
Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *UtilityTraceFunctionBarrierListModel::first() const
Returns the first UtilityTraceFunctionBarrier in the list model.
int UtilityTraceFunctionBarrierListModel::indexOf (Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *utilityTraceFunctionBarrier ) const
Returns the index of the provided utilityTraceFunctionBarrier in the list model.
void UtilityTraceFunctionBarrierListModel::insert(int index, Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *utilityTraceFunctionBarrier )
Inserts a utilityTraceFunctionBarrier at a specified index in the list model.
bool UtilityTraceFunctionBarrierListModel::isEmpty () const
Returns true if this list model is empty.
Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *UtilityTraceFunctionBarrierListModel::last() const
Returns the last UtilityTraceFunctionBarrier in the list model.
void UtilityTraceFunctionBarrierListModel::move(int from, int to)
Moves one UtilityTraceFunctionBarrier from an index in the list model to a different index.
void UtilityTraceFunctionBarrierListModel::removeAt (int index)
Removes a UtilityTraceFunctionBarrier at the specified index in the list model.
List models do not take ownership of the objects they contain. Therefore, removing or clearing objects from the list model will not delete those objects. An RAII technique should be used to ensure that memory is properly deallocated.
void UtilityTraceFunctionBarrierListModel::removeOne (Esri::ArcGISRuntime::UtilityTraceFunctionBarrier *utilityTraceFunctionBarrier )
Removes the specified utilityTraceFunctionBarrier from the list model.
List models do not take ownership of the objects they contain. Therefore, removing or clearing objects from the list model will not delete those objects. An RAII technique should be used to ensure that memory is properly deallocated.
[override virtual] int UtilityTraceFunctionBarrierListModel::size() const
Returns the number of trace function barriers in the model.
