public abstract class IlvBidiGraphic extends IlvGraphic
IlvBidiGraphic
is an abstract base class for graphic
objects that has a base text direction.
Besides the storage for the base text direction, it provides cached
access to locale and component orientation.
IlvBidiGraphic
is a base class for custom graphic objects,
that is, a subclass of
IlvGraphic
. Graphic objects are controlled using an
IlvManager
instance and displayed using one or more
IlvManagerView
instances in a Java Swing application.
For information about generic features for graphic objects, see
IlvGraphic.

if the bounding box depends on the locale.
Note: Most predefined graphic objects are independent of locale.
If this object is contained in a graphic bag that has a locale,
it returns the locale of that graphic bag. Otherwise it returns
IlvLocaleUtil.getCurrentULocale()
.
Typically a graphic object is in a manager that is displayed in a manager
view, and the returned value is the locale of the first manager view
that displays the graphic.

If this object is contained in a graphic bag that has a component
orientation, it returns the component orientation of that graphic bag.
Otherwise it returns ComponentOrientation.UNKNOWN

Typically a graphic object is in a manager that is displayed in a manager view, and the returned value is the component orientation of the first manager view that displays the graphic.

IlvBidiUtil.INHERITED_DIRECTION
:
the base text direction is inherited from the
graphic bag that contains this object.
If this object is not contained in a graphic bag,
the base text direction is calculated from the
component orientation.
IlvBidiUtil.COMPONENT_DIRECTION
:
the base text direction is calculated from the
component orientation.
IlvBidiUtil.LEFT_TO_RIGHT
:
the base text direction is left-to-right.
IlvBidiUtil.RIGHT_TO_LEFT
:
the base text direction is right-to-left.
IlvBidiUtil.CONTEXTUAL_DIRECTION
:
the base test direction is determined from the text
that is displayed according to the standard Bidi
algorithm, if the text contains at least one character
with a strong left-to-right or right-to-left direction.
If the text doesn't contain any character with a strong
direction, the real text direction is determined from
the current component orientation of the object.

IlvBidiUtil.INHERITED_DIRECTION
:
the base text direction is inherited from the

If this object is not contained in a graphic bag,
the base text direction is calculated from the
component orientation.
IlvBidiUtil.COMPONENT_DIRECTION
:
the base text direction is calculated from the

IlvBidiUtil.LEFT_TO_RIGHT
:
the base text direction is left-to-right.
IlvBidiUtil.RIGHT_TO_LEFT
:
the base text direction is right-to-left.

:

that is displayed according to the standard Bidi

with a strong left-to-right or right-to-left direction.
If the text doesn't contain any character with a strong

the current component orientation of the object.

getBaseTextDirection

public int getResolvedBaseTextDirection()
This method is similar to getBaseTextDirection()
but determines
the value when it is inherited from a parent component
(IlvBidiUtil.INHERITED_DIRECTION
) or dependent on
the component orientation (IlvBidiUtil.COMPONENT_DIRECTION
).
Hence, there are only 3 possible return values:
IlvBidiUtil.LEFT_TO_RIGHT
:
the base text direction is left-to-right.
IlvBidiUtil.RIGHT_TO_LEFT
:
the base text direction is right-to-left.
IlvBidiUtil.CONTEXTUAL_DIRECTION
:
the base test direction is determined from the text
that is displayed according to the standard Bidi
algorithm, if the text contains at least one character
with a strong left-to-right or right-to-left direction.
If the text doesn't contain any character with a strong
direction, the real text direction is determined from
the current component orientation of the object.
