## Implemented Interfaces

GdictStrategyChooser implements AtkImplementorIface, GtkBuildable and GtkOrientable.

## Properties

      "context"                  GdictContext*         : Read / Write / Construct

## Signals

      "strategy-activated"                             : Run Last

## Description

Each GdictContext allows matching a word using a specific "matching strategy". The GdictStrategyChooser widget queries a GdictContext and displays the list of available matching strategies.
