Detailed Description
Modifying this model (adding, removing, moving) will update the analysis overlays available in the scene view.
The model returns data for the following roles:
| Role | Type | Description | AnalysisOverlayRoles |
|---|---|---|---|
| analysisOverlayVisible | bool | The analysis overlay's visibility. | AnalysisOverlayVisibleRole |
Member Type Documentation
enum AnalysisOverlayListModel::AnalysisOverlayRoles
This enum specifies the custom roles which can be used with AnalysisOverlayListModel::data.
| Constant | Value | Description |
|---|---|---|
Esri::ArcGISRuntime::AnalysisOverlayListModel::AnalysisOverlayVisibleRole | Qt::UserRole + 1 | The analysis overlay's visibility. |
Member Function Documentation
[signal] void AnalysisOverlayListModel::errorOccurred (const Esri::ArcGISRuntime::Error &error)
Signal emitted when an error occurs.
- error - Details about the error.
[signal, since Esri::ArcGISRuntime 100.15] void AnalysisOverlayListModel::itemAdded (int index)
Signal emitted when an item is added to the list model.
- index - The index of the added item.
This function was introduced in Esri::ArcGISRuntime 100.15.
[signal, since Esri::ArcGISRuntime 100.15] void AnalysisOverlayListModel::itemRemoved (int index)
Signal emitted when an item is removed from the list model.
- index - The index of the removed item.
This function was introduced in Esri::ArcGISRuntime 100.15.
[override virtual] AnalysisOverlayListModel::~AnalysisOverlayListModel ()
Destructor.
void AnalysisOverlayListModel::append(Esri::ArcGISRuntime::AnalysisOverlay *analysisOverlay )
Appends an analysisOverlay to the analysis overlay list model.
[override virtual] Esri::ArcGISRuntime::AnalysisOverlay *AnalysisOverlayListModel::at(int index) const
Returns the analysis overlay at the specified index.
void AnalysisOverlayListModel::clear()
Removes all analysis overlays 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 AnalysisOverlayListModel::contains(Esri::ArcGISRuntime::AnalysisOverlay *analysisOverlay ) const
Returns true if the list model contains the specified analysisOverlay.
[override virtual] QVariant AnalysisOverlayListModel::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 analysis overlay referred to by the index.
- index. The index in the model for which to return data.
- role. The role for which to return data.
An empty value is returned if the specified index is out of range.
Esri::ArcGISRuntime::AnalysisOverlay *AnalysisOverlayListModel::first() const
Returns the first analysis overlay in the list model.
int AnalysisOverlayListModel::indexOf (Esri::ArcGISRuntime::AnalysisOverlay *analysisOverlay ) const
Returns the index of the analysisOverlay specified.
void AnalysisOverlayListModel::insert(int index, Esri::ArcGISRuntime::AnalysisOverlay *analysisOverlay )
Inserts an analysisOverlay at a specified index in the list model.
This method will append to the list if the index is greater than the current size of the list model.
bool AnalysisOverlayListModel::isEmpty () const
Returns true if the list model contains no analysis overlays.
Esri::ArcGISRuntime::AnalysisOverlay *AnalysisOverlayListModel::last() const
Returns the last analysis overlay in the list model.
void AnalysisOverlayListModel::move(int from, int to)
Moves one analysis overlay from an index in the list model to a different index.
void AnalysisOverlayListModel::removeAt (int index)
Removes an analysis overlay at the specified index.
No analysis overlay will be removed if the specified index is out of range.
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 AnalysisOverlayListModel::removeOne (Esri::ArcGISRuntime::AnalysisOverlay *analysisOverlay )
Removes the specified analysisOverlay 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 AnalysisOverlayListModel::size() const
Returns the number of analysis overlays contained in the list model.
