Detailed Description

Note: You cannot declare or create a component of this type in QML code.

Modifying this model (adding, removing, moving) will update the elevation sources available in the Scene.

The model returns data for the following roles:

RoleTypeDescription
namestringThe elevation source's name.
elevationSourceEnabledboolIf the elevation source is enabled.
elevationSourceTypeEnums.ElevationSourceTypeThe type of elevation source.

Property Documentation

count : int

Returns the number of objects in the model (read-only).


error : Error

Returns the error object in case an error occurs (read-only).


Signal Documentation

countChanged()

Emitted when the count property of the model changes.

Note: The corresponding handler is onCountChanged.


elevationSourceAdded(int index)

Emitted when an object is added to the list model at the index specified in the parameter.

Note: The corresponding handler is onElevationSourceAdded.


elevationSourceRemoved(int index)

Emitted when an object is removed from the list model at the index specified in the parameter.

Note: The corresponding handler is onElevationSourceRemoved.


errorChanged()

Emitted when the error property changes, which can indicate that an error occurred.

Note: The corresponding handler is onErrorChanged.


Method Documentation

void append(ElevationSource elevationSource)

Appends an elevationSource to the elevation source list model.


void clear()

Removes all elevation sources from the list model.


bool contains(ElevationSource elevationSource)

Returns true if the list model contains the specified elevationSource.


void forEach(callback)

Receives a callback function to execute for each elevation source in the model.

The callback function can take 0 to 3 optional arguments, in order:

Returns undefined if no error occurred, and an error message otherwise.

const error = elevationSourceListModel.forEach(function(element, index, array) {
    ...
});
if (error) {
    console.error(error.message);
}

ElevationSource get(int index)

Returns the ElevationSource at the specified index.


int indexOf(ElevationSource elevationSource)

Returns the index of the elevation source (elevationSource) specified.

This method was introduced in Esri::ArcGISRuntime 100.5..


void insert(int index, ElevationSource elevationSource)

Inserts an elevationSource at a specified index in the list.


void move(int from, int to)

Moves one elevation source from an index in the list model to a different index.


void remove(int index, int count = 1)

Removes one or more objects starting at the specified index.

  • index Index of first object to remove.
  • count Number of objects to remove. This parameter defaults to 1.

void removeOne(ElevationSource elevationSource)

Removes the specified elevation source (elevationSource) from the list model.

This method was introduced in Esri::ArcGISRuntime 100.5..


void setProperty(int index, string property, variant value)

Changes the property of the elevation source at index in the list model to value.
