◆ getAllocation()

void dw::Textblock::TextblockIterator::getAllocation	(	int	start,
		int	end,
		core::Allocation *	allocation
	)

virtual

Return the shape, which a part of the item, the iterator points on, allocates.

The parameters start and end have the same meaning as in DwIterator::highlight().

◆ getContentInFlow()

void dw::Textblock::TextblockIterator::getContentInFlow	(	int	index,

◆ highlight()

void dw::Textblock::TextblockIterator::highlight	(	int	start,
		int	end,
		core::HighlightLayer	layer
	)

virtual

Extend highlighted region to contain part of the current content.

For text, start and end define the characters, otherwise, the shape is defined as [0, 1], i.e. for highlighting a whole dw::core::Content, pass 0 and >= 1. To unhighlight see also dw::core::Iterator::unhighlight.

int dw::Textblock::TextblockIterator::numContentsInFlow ( )

Definition at line 274 of file textblock_iterator.cc.

◆ unhighlight()

void dw::Textblock::TextblockIterator::unhighlight	(	int	direction,
		core::HighlightLayer	layer
	)

virtual

Shrink highlighted region to no longer contain the current content.

The direction parameter indicates whether the highlighted region should be reduced from the start (direction > 0) or from the end (direction < 0). If direction is 0 all content is unhighlighted.
