Package-level Javadoc
Provides classes that help communicate proper content for fields in dialogs and wizards.
Package Specification
This package provides classes that can be used to guide a dialog user through choosing
appropriate content for fields in a dialog or wizard.
A ContentProposalAdapter can be attached to an arbitrary control to provide
a popup showing content proposals. These proposals appear when the defined
assist keystroke is invoked. The ContentProposalAdapter manages the creation,
hiding, and showing of the proposal popup, as well as the proper handling of key events
between the adapted control and its popup. Implementors of IControlContentAdapter
allow the adapter to set and retrieve the contents of the supplied control.
An AutoCompleteField configures a ContentProposalAdapter in a manner
that supports automatic field completion popups that filter based on the control's
contents.
ControlDecoration can be used to decorate an arbitrary control with
an image that communicates information about the control's content. Decorations can be
used to show additional information about a field, such as its status, or a cue
that shows availability of content proposals. Decorations are defined in pre-defined
locations relative to the control, and can be set up to show at all times, or only
when the control has focus. It is up to the client to ensure there is enough
space allocated to render the control decoration. Decorations can optionally show
descriptive text when the user hovers over them.
DecoratedField can also be used to decorate a control. The main difference
is that decorated fields reserve space for multiple decorations in particular
locations around the control. To do this, the field manages the creation of the
field's control, using a specialized layout to ensure there is adequate space
reserved for decorations around the control. Other than using the field to manage
the decorations themselves, clients are expected to interact
directly with the control.
Note: None of the classes in this package maintain global state.
