Detailed Description
The angular position may be different for each feature (driven by one or more feature attributes) or constant for all features (specified by a fixed number).
This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.
| Type | Default Property |
|---|---|
| ArcadeExpression | angleExpression |
See also JsonSerializable.
Property Documentation
[default] angleExpression : ArcadeExpression |
Specifies how the angle (in degrees) is calculated from the feature attributes, using an Arcade expression.
The calculation may use attributes, fixed numbers, or a combination of both. The default value is an ArcadeExpression containing an empty expression string, which will produce a zero angle when evaluated.
json : jsobject |
JSON data that can be used to instantiate the LabelAngle.
rotationType : Enums.LabelAngleRotationType |
Whether the angle should be interpreted as arithmetic or geographic.
The default value is Enums.LabelAngleRotationTypeAutomatic (which will be interpreted as Enums.LabelAngleRotationTypeArithmetic).
Signal Documentation
angleExpressionChanged() |
Emitted when the angleExpression property changes.
Note: The corresponding handler is onAngleExpressionChanged.
rotationTypeChanged() |
Emitted when the rotationType property changes.
Note: The corresponding handler is onRotationTypeChanged.
