Deprecated. As of 3.3, this class is no longer necessary.

public class FieldAssistColors
- extends
Object
FieldAssistColors defines protocol for retrieving colors that can be used to
provide visual cues with fields. For consistency with JFace dialogs and
wizards, it is recommended that FieldAssistColors is used when colors are
used to annotate fields.
Color resources that are returned using methods in this class are maintained
in the JFace color registries, or by SWT. Users of any color resources
provided by this class are not responsible for the lifecycle of the color.
Colors provided by this class should never be disposed by clients. In some
cases, clients are provided information, such as RGB values, in order to
create their own color resources. In these cases, the client should manage
the lifecycle of any created resource.

public FieldAssistColors()

Deprecated.
computeErrorFieldBackgroundRGB
public static
RGB computeErrorFieldBackgroundRGB(
Control control)
-
Deprecated.
- Compute the RGB of the color that should be used for the background of a
control to indicate that the control has an error. Because the color
suitable for indicating an error depends on the colors set into the
control, this color is always computed dynamically and provided as an RGB
value. Clients who use this RGB to create a Color resource are
responsible for managing the life cycle of the color.
This color is computed dynamically each time that it is queried. Clients
should typically call this method once, create a color from the RGB
provided, and dispose of the color when finished using it.
-
-
Parameters:
-
control - the control for which the background color should be computed.
-
Returns:
- the RGB value indicating a background color appropriate for
indicating an error in the control.
getRequiredFieldBackgroundColor
public static
Color getRequiredFieldBackgroundColor(
Control control)
-
Deprecated.
- Return the color that should be used for the background of a control to
indicate that the control is a required field and does not have content.
This color is managed by FieldAssistResources and should never be
disposed by clients.
-
-
Parameters:
-
control - the control on which the background color will be used.
-
Returns:
- the color used to indicate that a field is required.
