Detailed Description
Modifying this model (adding, removing, moving) results in updates to any objects that are currently referencing these subtype sublayers.
The model returns data for the following roles:
| Role | Type | Description | SubtypeSublayerRoles |
|---|---|---|---|
| name | QString | The subtypeSublayer's name. | SublayerNameRole |
| sublayerVisible | bool | Whether the subtypeSublayer is enabled to be visible. | SublayerVisibleRole |
| showInLegend | bool | Whether the subtypeSublayer will be shown in the legend. | SublayerShowInLegendRole |
| sublayerId | int | The subtypeSublayer's ID. | SublayerIdRole |
| minScale | double | The minumum scale at which the subtypeSublayer displays. | SublayerMinScaleRole |
| maxScale | double | The maximum scale at which the subtypeSublayer displays. | SublayerMaxScaleRole |
| sublayerType | ArcGISSublayerType | The subtypeSublayer's type. | SublayerTypeRole |
| canChangeVisibility | bool | Whether the subtypeSublayer's visibility can be changed. | SublayerCanChangeVisibilityRole |
| definitionExpression | QString | The subtypeSublayer's definition expression | SublayerDefinitionExpressionRole |
| sublayerOpacity | float | The subtypeSublayer's opacity | SublayerOpacityRole |
| scaleSymbols | bool | Whether the subtypeSublayer renderers its symbols based on scale | SublayerScaleSymbolsRole |
| labelsEnabled | bool | Whether the subtypeSublayer's labels are displayed | SublayerLabelsEnabledRole |

- error - Details about the error.
[signal] void SubtypeSublayerListModel::subtypeSublayerAdded(int index)
Signal emitted when a subtypeSublayer is added to the list model.
index is the index of the added subtypeSublayer.
[signal] void SubtypeSublayerListModel::subtypeSublayerRemoved(int index)
Signal emitted when a subtypeSublayer is removed from the list model.
index is the index of the removed subtypeSublayer.
[override virtual] SubtypeSublayerListModel::~SubtypeSublayerListModel()
Destructor.
void SubtypeSublayerListModel::append(Esri::ArcGISRuntime::SubtypeSublayer *subtypeSublayer)
Appends a subtypeSublayer to the subtypeSublayer list model.
[override virtual] Esri::ArcGISRuntime::SubtypeSublayer *SubtypeSublayerListModel::at(int index) const
Returns the subtypeSublayer at the specified index.
void SubtypeSublayerListModel::clear()
Removes all sublayers from the list model.
bool SubtypeSublayerListModel::contains(Esri::ArcGISRuntime::SubtypeSublayer *subtypeSublayer) const
Returns true if the list model contains the specified subtypeSublayer.
[override virtual] QVariant SubtypeSublayerListModel::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 subtypeSublayer 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::SubtypeSublayer *SubtypeSublayerListModel::first() const
Returns the first subtypeSublayer in the list model.
int SubtypeSublayerListModel::indexOf(Esri::ArcGISRuntime::SubtypeSublayer *subtypeSublayer) const
