Method Summary

Modifier and Type	Method and Description
void	actionPerformed(java.awt.event.ActionEvent e) The general algorithm here is to find the two selected nodes that are furthest apart, and then to distribute all other selected nodes along the straight line between these nodes.

protected void	updateEnabledState() Override in subclasses to update the enabled state of the action when something in the JOSM state changes, i.e.
protected void	updateEnabledState(java.util.Collection<? extends OsmPrimitive> selection) Override in subclasses to update the enabled state of the action if the collection of selected primitives changes.

public void actionPerformed(java.awt.event.ActionEvent e)

The general algorithm here is to find the two selected nodes that are furthest apart, and then to distribute all other selected nodes along the straight line between these nodes.

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
