Group of branding interfaces
Interface NameIn/OutStabilitySpecified in What Document?

There is a way to enable mnemonics in popup menu items created via
Actions factory methods in your own application build on top of NetBeans Platform. Just provide branding for org/openide/awt/ file and modify USE_MNEMONICS=always. Other possible values of this key include default, never or always.

Group of logger interfaces
Interface NameIn/OutStabilitySpecified in What Document?

There is a special support for notifying when an action wrapped by
Actions bridge is invoked and how. The support is using Logger.getLogger("org.netbeans.ui.actions") and sents a LogRecord with message UI_ACTION_BUTTON_PRESS, FINER level and paramerters:
  • {0} instance of the button
  • {1} class of the button
  • {2} instance of the action
  • {3} class of the action
  • {4} display name of the action
whenever such action is invoked. This message can then be consumed by enhanced UI logger that track what the user is going.

Group of systemproperty interfaces
Interface NameIn/OutStabilitySpecified in What Document?

Status text set in
StatusDisplayer is by default shown in status line of NetBeans and is hidden after specified timeout. If not overriden by this property it is done after 5000ms. O means that the last text will be shown and not removed.

org.openide.awt.ActionReference.completionExportedUnder Development

System.getProperty("org.openide.awt.ActionReference.completion") is specified, then the dedicated processor for ActionReference tries to load such class, casts it to Processor and asks it for additional completion items for its path attribute. By default, when running inside NetBeans IDE, apisupport.project registers such class and provides items representing valid paths in current project.

Group of lookup interfaces
Interface NameIn/OutStabilitySpecified in What Document?

Objects implementing ButtonActionConnector are looked up. Only the first instance found in the loookup is used to provide an alternative implementation of connection between Actions and GUI components. If there isn't one in the lookup the default implementation is used (it means there does not have to be one).

Group of layer interfaces
Interface NameIn/OutStabilitySpecified in What Document?

Many action factories (alwaysEnabled, context and callback, etc.) are ready to be called directly from layer XML file.

Implementation Details

Where are the sources for the module?

The sources for the module are in the NetBeans Mercurial repositories.

What do other modules need to do to declare a dependency on this one, in addition to or instead of a plain module dependency?
