SuggesterFX

SuggesterFX is a JavaFX lightweight library that provides a suggestion (autocompletion) system for text fields linked to data entries. This library integrates with mvciFX library to provide a clean, maintainable architecture for handling suggestions and autocompletion.

Credits

• Original MVCI framework concept by Dave Barrett (PragmaticoCoding).
• Built on ControlsFX components
• Autocompletion modifications based on Clément Grennerat's post and his PDF4Teachers application

Overview

SuggesterFX combines JavaFX's text fields with ControlsFX's autocompletion features, wrapped in an MVCI (Model-View-Controller-Interactor) architecture. This makes it easy to implement type-ahead suggestions while maintaining clean separation of concerns.

Features

This library provides the following components:

• SuggestionInteractor: an abstract MVCI Interactor class specialized for suggestions handling
  • fetches entries based on user input
  • retrieves text suggestions
  • manages model updates after suggestion selection
• Entry: an interface representing data entities (such as POJOs) that can be used with the suggestion system.
  • Supports composite primary keys
  • Provides description text for display
• Suggestion Components:
  • EntryConverter: converts between Entry objects and their string representations.
  • EntrySelectionHandler: handles the selection events from auto-completion textfield. It uses the SuggestionInteractor to handle what should be done after the operation is completed.
  • EntrySuggesterCallback: a callback backed by the SuggestionInteractor.fetchEntries(String) method, which retrieves entries based on a user's suggestion or partial input.
  • StringSuggesterCallback: a callback backed by to SuggestionInteractor.fetchNames(String) method, which retrieves a list of names matching a user's suggestion or partial input

ControlsFX autocompletion widgets and classes

The classes in com.maemlab.suggesterfx.controlsfx.autocompletion package are taken from ControlsFX. They have been repackaged and modified following Clément Grennerat's post.

• impl.textfield.AutoCompletionBinding:
  • Removed EventTarget implementation
  • Simplified fireAutoCompletion method:
  • Made isCancelled and getUserText methods public
  • Removed invalidated method
• impl.textfield.TextFields: removed createClearablePasswordField method
• impl.textfield.AutoCompletionTextFieldBinding: a little bit of code review
• impl.skin.AutoCompletePopupSkin: removed the default style
