Detailed Description

Modifying this model (adding, removing, moving) will update the SolidStrokeSymbolLayer.

The model returns data for the following roles:

geometricEffectTypeEnums.GeometricEffectTypeThe Enums.GeometricEffectType enum.

Property Documentation

count : int

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

error : Error

Returns the Error object (read-only).

Signal Documentation


Emitted when the count property of the model changes.


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

geometricEffectAdded(int index)

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

geometricEffectRemoved(int index)

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

Method Documentation

void append(GeometricEffect geometricEffect)

Appends a geometricEffect to the geometric effects list model.

void clear()

Removes all geometric effects from the list model.

bool contains(GeometricEffect geometricEffect)

Returns true if the list model contains the specified symbol.

void forEach(callback )

Receives a callback function to execute for each symbol 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.

var error = GeometricEffectListModel.forEach(function(element, index, array) {
if (error) {

GeometricEffect get(int index) const

Returns the GeometricEffect at the specified index.

int indexOf(GeometricEffect geometricEffect)

Returns the index of the geometric effect (geometricEffect) specified.

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

void insert(int index, Symbol symbol)

Inserts a geometricEffect at a specified index in the list.

void move(int from, int to)

Moves one symbol 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(GeometricEffect geometricEffect)

Removes the specified geometric effect (geometricEffect) from the list model.

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