public abstract class DockingAction extends Object implements DockingActionIf
DockingAction defines a user action associated with a toolbar icon and/or menu item. All actions must specify an action name which will be used to associate key bindings and will be used as the popup menu item when needed. This name should be unique across the entire application.

DockingActions can be invoked from the global menu, a popup menu, a toolbar, and/or a keybinding, depending on whether or not menuBarData, popupMenuData, toolBarData, and/or keyBindingData have been set.

Implementors of this class should override actionPerformed(ActionContext).

Generally, implementors should also override isEnabledForContext(ActionContext). This method is used to determine if an action if applicable to the current context. Overriding this method allows actions to manage their own enablement. Otherwise, the default behavior for this method is to return the current enabled property of the action. This allows for the possibility for plugins to externally manage the enablement of its actions.

NOTE: If you wish to do your own external enablement management for an action (which is highly discouraged), it is very important that you don't use any of the internal enablement mechanisms by setting the predicates enabledWhen(Predicate), validContextWhen(Predicate) or overriding isValidContext(ActionContext). These predicates and methods trigger internal enablement management which will interfere with you own calls to setEnabled(boolean).

    • isAddToPopup

      public boolean isAddToPopup(ActionContext context)
      Description copied from interface: DockingActionIf
      method is used to determine if this action should be displayed on the current popup. This method will only be called if the action has popup PopupMenuData set.

      Generally, actions don't need to override this method as the default implementation will defer to the DockingActionIf.isEnabledForContext(ActionContext), which will have the effect of adding the action to the popup only if it is enabled for a given context. By overriding this method, you can change this behavior so that the action will be added to the popup, even if it is disabled for the context, by having this method return true even if the DockingActionIf.isEnabledForContext(ActionContext) method will return false, resulting in the action appearing in the popup menu, but begin disabled.

      Specified by:
      isAddToPopup in interface DockingActionIf
      Parameters:
      context - the ActionContext from the active provider.
      Returns:
      true if this action is appropriate for the given context.

    • isEnabledForContext

      public boolean isEnabledForContext(ActionContext context)
      Description copied from interface: DockingActionIf
      Method used to determine if this action should be enabled for the given context.

      This is the method implementors override to control when the action may be used.

      This method will be called by the DockingWindowManager for actions on the global menuBar and toolBar and for actions that have a keyBinding.

      This method will be called whenever one of the following events occur:

      1. when the user invokes the action via its keyBinding,
      2. the user changes focus from one component provider to another,
      3. the user moves a component to another position in the window or into another window,
      4. a component provider reports a change in it's context,
      5. any plugin or software component reports a general change in context (calls the tool.contextChanged(ComponentProvider) with a null parameter).
      The default implementation will simply return this action's enablement state.
      Specified by:
      isEnabledForContext in interface DockingActionIf
      Parameters:
      context - the current ActionContext for the window.
      Returns:
      true if the action should be enabled for the context or false otherwise.

    • isValidContext

      public boolean isValidContext(ActionContext context)
      Description copied from interface: DockingActionIf
      Method that actions implement to indicate if this action is valid (knows how to work with, is appropriate for) for the given context. This method is used to determine if the action should be enabled based on the either the local context or the global context. The action is first asked if it is valid for the local context and if not, then it is asked if it is valid for the global context. If a context is valid, then it will then be asked if it is enabled for that context.
      Specified by:
      isValidContext in interface DockingActionIf
      Parameters:
      context - the ActionContext from the active provider.
      Returns:
      true if this action is appropriate for the given context.

    • shouldAddToWindow

      public final boolean shouldAddToWindow(boolean isMainWindow, Set<Class<?>> contextTypes)
      Determines if this action should be added to a window.

      If the client wants the action on all windows, then they can call shouldAddToAllWindows

      If the client wants the action to be on a window only when the window can produce a certain context type, the the client should call addToWindowWhen(Class)

      Otherwise, by default, the action will only be on the main window.

      Specified by:
      shouldAddToWindow in interface DockingActionIf
      Parameters:
      isMainWindow - true if the window in question is the main window
      contextTypes - a list of contextTypes (Classes) based on the providers that are currently in the window.
