bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	47 * DecoratedField manages image decorations around a control. It allows clients
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	48 * to specify an image decoration and a position for the decoration relative to
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	49 * the field. Decorations may be assigned descriptions, which are shown when the
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	50 * user hovers over the decoration. Clients can decorate any kind of control by
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	51 * supplying a {@link IControlCreator} to create the control that is decorated.
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	52 * <p>
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	53 * Decorations always appear on either horizontal side of the field, never above
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	54 * or below it. Decorations can be positioned at the top or bottom of either
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	55 * side. Future implementations may provide additional positioning options for
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	56 * decorations.
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	57 * <p>
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	58 * By default, DecoratedField will consult the {@link FieldDecorationRegistry}
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	59 * to determine how much space should be reserved for each decoration. This
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	60 * allows fields with decorations from different sources to align properly on
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	61 * the same dialog, since the registry tracks the size of all decorations
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	62 * registered. Therefore, it is recommended, but not required, that clients of
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	63 * DecoratedField register the decorations used. In cases where alignment
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	64 * between different fields is not a concern, clients can use
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	65 * <code>setUseMaximumDecorationWidth(false)</code> and need not register
bc29606a740c Added dwt-addons in original directory structure of eclipse.org Frank Benoit <benoit@tionex.de> parents: diff changeset	66 * their decorations.
