Member Function Documentation

virtual BidiCharType CEGUI::BiDiVisualMapping::getBidiCharType ( const utf32  char_to_check) const
pure virtual

Gets the BiDi char type of a char.

Parameters
charToCheckThe utf32 character code that will be checked.
Returns
One of the BidiCharType enumerated values indicating the BiDi char type.

Implemented in CEGUI::FribidiVisualMapping, and CEGUI::MinibidiVisualMapping.

virtual bool CEGUI::BiDiVisualMapping::reorderFromLogicalToVisual ( const String logical,
String visual,
StrIndexList l2v,
StrIndexList v2l 
) const
pure virtual

Reorder a string from a logical (type order) bidi string to a visual (the way it displayed) string.

Parameters
logicalString object to be reordered.
visualString object containing the result reordered string.
l2vMappingList of integers that map the pos of each char from logical string in the visual string.
v2lMappingList of integers that map the pos of each char from visual string in the logical string.
Returns
  • true if successful.
  • false if the operation failed.

Implemented in CEGUI::FribidiVisualMapping, and CEGUI::MinibidiVisualMapping.

bool CEGUI::BiDiVisualMapping::updateVisual ( const String logical)

Use reorderFromLogicalToVisual to update the internal visual mapping data and visual string representation based upon the logical string logical.

Parameters
logicalString object representing the logical text order.
Returns
  • true if the update was a success.
  • false if something went wrong.
