Controlling Default Bidirectional Attributes Through the API

Support of Bidirectional and Contextual Languages > Default Bidirectional Attributes of the IlvDisplay > Controlling Default Bidirectional Attributes Through the API

The following functions are declared in the header file <ilviews/bidi/bidi.h>.

IlvGetDefaultBidiValues retrieves the default values of the bidirectional attributes. No resource allocation is performed. The pointers passed as its parameters must point to places in memory that are already allocated. You can also provide a null pointer. In this case, the corresponding attribute is ignored.

void

IlvGetDefaultBidiValues(IlvDisplay* display,

IlvNumerals* numerals,

IlvSwapping* swapping,

IlvLayoutDirection* layoutDirection,

IlvShaping* shaping,

IlvWordBreak* wordBreak);

The following functions set the default bidirectional attributes for the specified display. The val parameter indicates the new default value assigned to the attribute:

void

IlvSetDefaultNumerals(IlvDisplay* display, IlvNumerals val);

void

IlvSetDefaultSwapping(IlvDisplay* display, IlvSwapping val);

void

IlvSetDefaultLayoutDirection(IlvDisplay* display, IlvLayoutDirection val);

void

IlvSetDefaultShaping(IlvDisplay* display, IlvShaping val);

void

IlvSetDefaultWordBreak(IlvDisplay* display, IlvWordBreak val);

The following function is similar to the previous ones except that it sets all the default bidirectional attributes at once:

void

IlvSetDefaultBidiValues(IlvDisplay* display,

IlvNumerals numerals,

IlvSwapping swapping,

IlvLayoutDirection layoutDirection,

IlvShaping shaping,

IlvWordBreak wordBreak);
