org.eclipse.graphiti.util.PredefinedColoredAreas

All Implemented Interfaces:

IPredefinedRenderingStyle

public class PredefinedColoredAreas
extends Object
implements IPredefinedRenderingStyle

Predefined gradient color-areas to be used in GFFigureUtil with method paintColorFlow(..). This class comprises the definitions for predefined gradients and their adaptations for one or more visual states: IPredefinedRenderingStyle.STYLE_ADAPTATION_DEFAULT, IPredefinedRenderingStyle.STYLE_ADAPTATION_PRIMARY_SELECTED , IPredefinedRenderingStyle.STYLE_ADAPTATION_SECONDARY_SELECTED, IPredefinedRenderingStyle.STYLE_ADAPTATION_ACTION_ALLOWED, IPredefinedRenderingStyle.STYLE_ADAPTATION_ACTION_FORBIDDEN. Gradient definitions have corresponding ID's: IPredefinedRenderingStyle.BLUE_WHITE_GLOSS_ID, IPredefinedRenderingStyle.BLUE_WHITE_GLOSS_ID, IPredefinedRenderingStyle.BLUE_WHITE_ID, IPredefinedRenderingStyle.LIGHT_YELLOW_ID, IPredefinedRenderingStyle.LIGHT_GRAY_ID, IPredefinedRenderingStyle.COPPER_WHITE_GLOSS_ID, IPredefinedRenderingStyle.SILVER_WHITE_GLOSS_ID. A Gradient definition for a shape can be set as a rendering style with IGaService.setRenderingStyle(AbstractStyle, AdaptedGradientColoredAreas) . The AdaptedGradientColoredAreas gradient definitions are retrieved by getter methods defined here, like getBlueWhiteGlossAdaptions(). Clients may create their own gradient definition by overriding PredefinedColoredAreas for gradient definitions and IPredefinedRenderingStyle for corresponding ID's. Simply follow straightforward the example getBlueWhiteGlossAdaptions(). It is recommended to support at least IPredefinedRenderingStyle.STYLE_ADAPTATION_DEFAULT, IPredefinedRenderingStyle.STYLE_ADAPTATION_PRIMARY_SELECTED, IPredefinedRenderingStyle.STYLE_ADAPTATION_SECONDARY_SELECTED as visual states.

Method Details

getBlueWhiteGlossAdaptions

public static AdaptedGradientColoredAreas getBlueWhiteGlossAdaptions()

Returns:

AdaptedGradientColoredAreas color-areas for IPredefinedRenderingStyle.BLUE_WHITE_GLOSS_ID with the adaptations: IPredefinedRenderingStyle.STYLE_ADAPTATION_DEFAULT, IPredefinedRenderingStyle.STYLE_ADAPTATION_PRIMARY_SELECTED, IPredefinedRenderingStyle.STYLE_ADAPTATION_SECONDARY_SELECTED, IPredefinedRenderingStyle.STYLE_ADAPTATION_ACTION_ALLOWED, IPredefinedRenderingStyle.STYLE_ADAPTATION_ACTION_FORBIDDEN.

getBlueWhiteAdaptions

public static AdaptedGradientColoredAreas getBlueWhiteAdaptions()

Returns:

AdaptedGradientColoredAreas color-areas for IPredefinedRenderingStyle.BLUE_WHITE_ID with the adaptations: IPredefinedRenderingStyle.STYLE_ADAPTATION_DEFAULT, IPredefinedRenderingStyle.STYLE_ADAPTATION_PRIMARY_SELECTED, IPredefinedRenderingStyle.STYLE_ADAPTATION_SECONDARY_SELECTED.

getLightYellowAdaptions

public static AdaptedGradientColoredAreas getLightYellowAdaptions()

Returns:

AdaptedGradientColoredAreas color-areas for IPredefinedRenderingStyle.LIGHT_YELLOW_ID with the adaptations: IPredefinedRenderingStyle.STYLE_ADAPTATION_DEFAULT, IPredefinedRenderingStyle.STYLE_ADAPTATION_PRIMARY_SELECTED, IPredefinedRenderingStyle.STYLE_ADAPTATION_SECONDARY_SELECTED.

getLightGrayAdaptions

public static AdaptedGradientColoredAreas getLightGrayAdaptions()

Returns:

AdaptedGradientColoredAreas color-areas for IPredefinedRenderingStyle.LIGHT_GRAY_ID with the adaptations: IPredefinedRenderingStyle.STYLE_ADAPTATION_DEFAULT, IPredefinedRenderingStyle.STYLE_ADAPTATION_PRIMARY_SELECTED.

getCopperWhiteGlossAdaptions

public static AdaptedGradientColoredAreas getCopperWhiteGlossAdaptions()

Returns:

AdaptedGradientColoredAreas color-areas for IPredefinedRenderingStyle.COPPER_WHITE_GLOSS_ID with the adaptation IPredefinedRenderingStyle.STYLE_ADAPTATION_DEFAULT.

getSilverWhiteGlossAdaptions

public static AdaptedGradientColoredAreas getSilverWhiteGlossAdaptions()

Returns:

AdaptedGradientColoredAreas color-areas for IPredefinedRenderingStyle.SILVER_WHITE_GLOSS_ID with the adaptation IPredefinedRenderingStyle.STYLE_ADAPTATION_DEFAULT.

getAdaptedGradientColoredAreas

public static AdaptedGradientColoredAreas getAdaptedGradientColoredAreas(String id)

Get AdaptedGradientColoredAreas by id. The id should be defined in IPredefinedRenderingStyle or in an extension. This is a helper method for tests etc. Please use methods like getBlueWhiteGlossAdaptions() to set the rendering style with IGaService.setRenderingStyle(AbstractStyle, AdaptedGradientColoredAreas) . Clients should override this method, if they have own gradient definitions and id's.

Parameters:

id - The id which designates a corresponding AdaptedGradientColoredAreas object.

Returns:

the corresponding AdaptedGradientColoredAreas object or null, if id is not defined.

addGradientColoredArea

protected static void addGradientColoredArea(org.eclipse.emf.common.util.EList<GradientColoredArea> gcas,
 String colorStart,
 int locationValueStart,
 LocationType locationTypeStart,
 String colorEnd,
 int locationValueEnd,
 LocationType locationTypeEnd)

createGradientColoredArea

protected static GradientColoredArea createGradientColoredArea(String colorStart,
 int locationValueStart,
 LocationType locationTypeStart,
 String colorEnd,
 int locationValueEnd,
 LocationType locationTypeEnd)

Since:

0.10

getLocation

public static int getLocation(GradientColoredLocation gradientColoredLocation,
 int length,
 double zoom)

Returns the location for the given length and zoom-factor. The location is calculated from the location-value and location-type in relation to the given length and zoom-factor.

The idea is, that the location-type specifies how to interpret the location-value in relation to the length. For example if the location-type is "relative" and the location-value is "40", then this means, that the location is at 40% of the length. So for a length of 200 the location would be 80.

Parameters:

length - The length, for which to calculate the location.

zoom - The zoom-factor, which to use on the location-value.

Returns:

The location for the given length and zoom-factor.
