public interface DockingActionIf extends HelpDescriptor
The base interface for clients that wish to create commands to be registered with a tool.

An action may appear in a primary menu, a popup menu or a toolbar. Further, an action may have a key binding assigned.

The particular support for key bindings is defined by KeyBindingType. Almost all client actions will use the default setting of KeyBindingType.INDIVIDUAL. To control the level of key binding support, you can pass the desired KeyBindingType to the base implementation of this interface.

ActionContext is a key concept for tool actions so that they can be context sensitive if appropriate. The context provides a consistent way for plugins and components to share tool state with actions. Actions can then use that context to make decisions, such as if they should be enabled or added to a popup menu. The context information is also typically used when the action is invoked. For example, an action context from a table element may provide the row in a table component that is selected and then a "delete table row" action can use that information to be enabled when a table selection exists and then delete that row if the action is invoked.

Actions can optionally operate on a default context if the current active context is invalid for that action. This allows actions to work on a more global level than just the component that is focused (and yet give preference to the active context.) The idea is that if an action is not valid for the current focused context (and it has been configured to support default context using setContextClass(Class, boolean)), then it can be validated against a default action context for its specific action context type. The source for the default context depends on the context type. Default context providers are registered on the tool for each specific ActionContext type. See DockingWindowManager.registerDefaultContextProvider(Class, ActionContextProvider) for more details.

The use of default context is primarily intended for tool-level actions which are the ones that appear in the tool's main menu bar or toolbar. This allows the tool actions to mostly work on the tool's main component context regardless of what has focus, and yet still work on the focused component if appropriate (such as a snapshot of the main component).

    • actionPerformed

      void actionPerformed(ActionContext context)
      method to actually perform the action logic for this action.
      Parameters:
      context - the ActionContext object that provides information about where and how this action was invoked.

    • isAddToPopup

      boolean isAddToPopup(ActionContext context)
      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 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 isEnabledForContext(ActionContext) method will return false, resulting in the action appearing in the popup menu, but begin disabled.

      Parameters:
      context - the ActionContext from the active provider.
      Returns:
      true if this action is appropriate for the given context.

    • isValidContext

      boolean isValidContext(ActionContext context)
      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.
      Parameters:
      context - the ActionContext from the active provider.
      Returns:
      true if this action is appropriate for the given context.

    • isEnabledForContext

      boolean isEnabledForContext(ActionContext context)
      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.
      Parameters:
      context - the current ActionContext for the window.
      Returns:
      true if the action should be enabled for the context or false otherwise.

    • getInceptionInformation

      String getInceptionInformation()
      Returns a string that includes source file and line number information of where this action was created
      Returns:
      the inception information

    • createButton

      JButton createButton()
      Returns a JButton that is suitable for this action. For example, It creates a ToggleButton if the action is a ToggleDockingActionIf.
      Returns:
      a JButton to be used in a toolbar or null if the action does not have ToolBarData set.

    • createMenuItem

      JMenuItem createMenuItem(boolean isPopup)
      Returns a JMenuItem that is suitable for this action. For example, if the action is a ToggleDockingActionIf, then a JCheckBoxMenuItem will be created.
      Parameters:
      isPopup - true if the action should use its Popup MenuData, else it uses the MenuBar MenuData.
      Returns:
      a JMenuItem for placement in either the menu bar or a popup menu.

    • createMenuComponent

      default Component createMenuComponent(boolean isPopup)
      Returns a component to represent this action in the menu.

      Typically, this is the menu item that triggers the action. However, some actions may wish to use components other than menu items. For example, they may produce component for helping to organize the menu visually.

      Parameters:
      isPopup - true if the action should use its Popup MenuData, else it uses the MenuBar MenuData.
      Returns:
      the component
      See Also:

    • shouldAddToWindow

      boolean shouldAddToWindow(boolean isMainWindow, Set<Class<?>> contextTypes)
      Determines whether this action should be added to a window (either the main window or a secondary detached window). By default, this method will return true for the main window and false otherwise.
      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.
      Returns:
      true if this action should be added to the window, false otherwise.

    • getKeyBindingType

      default KeyBindingType getKeyBindingType()
      Returns this actions level of support for key binding accelerator keys

      Actions support key bindings by default. Some reserved actions do not support key bindings, while others wish to share the same key bindings with multiple, equivalent actions (this allows the user to set one binding that works in many different contexts).

      Returns:
      the key binding support

    • setKeyBindingData

      void setKeyBindingData(KeyBindingData keyBindingData)
      Sets the KeyBindingData on an action to either assign a keybinding or remove it (keyBindingData = null).
      Parameters:
      keyBindingData - if non-null, assigns a keybinding to the action. Otherwise, removes any keybinding from the action.

    • setUnvalidatedKeyBindingData

      void setUnvalidatedKeyBindingData(KeyBindingData newKeyBindingData)
      Users creating actions should not call this method, but should instead call setKeyBindingData(KeyBindingData).

      Call this method when you wish to bypass the validation of setKeyBindingData(KeyBindingData) so that keybindings are set exactly as they are given (such as when set by the user and not by the programmer).

      Parameters:
      newKeyBindingData - the KeyBindingData to be used to assign this action to a keybinding

    • dispose

      Returns:
      the class of a specific action context that this action requires for it to operate

    • supportsDefaultContext

      boolean supportsDefaultContext()
      Returns true if this action also supports operating on a default context other then the active (focused) provider's context. See the class header for more details.
      Returns:
      true if this action also supports operating on a default context other then the active (focused) provider's context.

    • setContextClass

      void setContextClass(Class<? extends ActionContext> type, boolean supportsDefaultContext)
      Sets the specific action context class that this action works on and if the action supports default context. See ActionContext for details on how the action context system works.
      Parameters:
      type - the ActionContext class that this action works on.
      supportsDefaultContext - if true, then this action also support operating on a default context other than the active (focused) provider's context.
