Member Function Documentation

CountRuns()

size_t CoreTextParagraphLayout::CoreTextLine::CountRuns ( ) const

inlineoverridevirtual

Get the number of runs in this line.

Returns

The number of runs.

Implements ParagraphLayouter::Line.

Definition at line 87 of file string_osx.cpp.

GetInternalCharLength()

int CoreTextParagraphLayout::CoreTextLine::GetInternalCharLength ( char32_t c ) const

inlineoverridevirtual

Get the number of elements the given character occupies in the underlying text buffer of the Layouter.

Many use UTF-16 internally, meaning a character larger than MAX_UINT16 occupies two places in its buffer.

Parameters

c	The character to get the length for.

Returns

The length.

Implements ParagraphLayouter::Line.

Definition at line 90 of file string_osx.cpp.

GetLeading()

int CoreTextParagraphLayout::CoreTextLine::GetLeading ( ) const

overridevirtual

Get the height of the line.

Returns

The maximum height of the line.

Implements ParagraphLayouter::Line.

Definition at line 241 of file string_osx.cpp.

GetVisualRun()

const VisualRun & CoreTextParagraphLayout::CoreTextLine::GetVisualRun ( size_t run ) const

inlineoverridevirtual

Get a reference to the given run.

Parameters

run	The index into the runs.

Returns

The reference to the run.

Implements ParagraphLayouter::Line.

Definition at line 88 of file string_osx.cpp.

GetWidth()

int CoreTextParagraphLayout::CoreTextLine::GetWidth ( ) const

overridevirtual

Get the width of this line.
