|
---|
41 | * Base class helper for all Actions in JOSM. Just to make the life easier.
|
---|
42 | *
|
---|
43 | * This action allows you to set up an icon, a tooltip text, a globally registered shortcut, register it in the main toolbar and set up
|
---|
44 | * layer/selection listeners that call {@link #updateEnabledState()} whenever the global context is changed.
|
---|
45 | *
|
---|
46 | * A JosmAction can register a {@link LayerChangeListener} and a {@link SelectionChangedListener}. Upon
|
---|
47 | * a layer change event or a selection change event it invokes {@link #updateEnabledState()}.
|
---|
48 | * Subclasses can override {@link #updateEnabledState()} in order to update the {@link #isEnabled()}-state
|
---|
49 | * of a JosmAction depending on the {@link #getLayerManager()} state.
|
---|
50 | *
|
---|
51 | * destroy() from interface Destroyable is called e.g. for MapModes, when the last layer has
|
---|
52 | * been removed and so the mapframe will be destroyed. For other JosmActions, destroy() may never
|
---|
53 | * be called (currently).
