public final class CreateCircleAction
extends JosmAction

- Create a new circle from two selected nodes or a way with 2 nodes which represent the diameter of the circle. - Create a new circle from three selected nodes--or a way with 3 nodes. - Useful for roundabouts Note: If a way is selected, it is changed. If nodes are selected a new way is created. So if you've got a way with nodes it makes a difference between running this on the way or the nodes! BTW: Someone might want to implement projection corrections for this...

updateEnabledState

protected void updateEnabledState()
Description copied from class: JosmAction
Override in subclasses to update the enabled state of the action when something in the JOSM state changes, i.e. when a layer is removed or added. See JosmAction.updateEnabledState(Collection) to respond to changes in the collection of selected primitives. Default behavior is empty.

Overrides:
updateEnabledState in class JosmAction

JosmAction.updateEnabledState(Collection), JosmAction.initEnabledState()

updateEnabledState

protected void updateEnabledState(java.util.Collection<? extends OsmPrimitive> selection)
Description copied from class: JosmAction
Override in subclasses to update the enabled state of the action if the collection of selected primitives changes. This method is called with the new selection.

Overrides:
updateEnabledState in class JosmAction
Parameters:
selection - the collection of selected primitives; may be empty, but not null
