Detailed Description

TextLayout is the base class for different implementations of text layouting.

It is a node since it sends layout-event

Member Function Documentation

LUMINOUS_API QUrl Luminous::TextLayout::findUrl ( Nimble::Vector2f  location) const
LUMINOUS_API float Luminous::TextLayout::verticalOffset ( ) const

This tells how much there is need to offset the vertical position of the layout.

It is necessary for enabling vertical alignment.

Returns
Offset for rendering this layout
