isEnabled property
True to allow interactive snapping, based on the configured SnapSettings.sourceSettings, false otherwise. Default is false.
If SnapSettings.isEnabled is true and a user edits a geometry interactively, then when the pointer is close to an existing snappable graphic or feature, the position of the interactive edit is adjusted to coincide with ("snap to") that graphic or feature. The content of SnapSettings.sourceSettings determines which sources of geometries can be used to snap to.
Setting this value temporarily to false may be useful if you wish to temporarily disable all snapping without affecting how snapping is currently configured. For example, changing this property will not affect the value of SnapSourceSettings.isEnabled, or if rule-based snapping has been configured by using SnapRules.
