|

[10353] | 44 | * 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
|
---|
| 45 | * layer/selection listeners that call {@link #updateEnabledState()} whenever the global context is changed.
|
---|
| 46 | *
|
---|
[13925] | 47 | * A JosmAction can register a {@link LayerChangeListener} and a {@link DataSelectionListener}. Upon
|
---|
[5275] | 48 | * a layer change event or a selection change event it invokes {@link #updateEnabledState()}.
|
---|
| 49 | * Subclasses can override {@link #updateEnabledState()} in order to update the {@link #isEnabled()}-state
|
---|
[10972] | 50 | * of a JosmAction depending on the {@link #getLayerManager()} state.
|
---|
[2305] | 51 | *
|
---|
[208] | 52 | * destroy() from interface Destroyable is called e.g. for MapModes, when the last layer has
|
---|
| 53 | * been removed and so the mapframe will be destroyed. For other JosmActions, destroy() may never
|
---|
| 54 | * be called (currently).
