Constructor & Destructor Documentation

ICUVisualRun()

ICUParagraphLayout::ICUVisualRun::ICUVisualRun	(	const ICURun &	run,
		int	x )

Constructor for a new ICUVisualRun.

It bases all information on the ICURun, which should already be shaped.

Parameters

run	The ICURun to base the visual run on.
x	The offset of the run on the line.

Definition at line 131 of file gfx_layout_icu.cpp.
