◆ lineOffsetsStack

AZStd::stack<UiTextComponent::LineOffsets*> UiTextComponentOffsetsSelector::lineOffsetsStack

A multi-line selection can be divided into three offsets: the first line (top), the last line (bottom), and a multi-line middle section that is basically a rect.

Each LineOffset contains a Vec2 for left and right offsets. The left offset is "absolute" for the element rect whereas the right offset is relative to the left offset.

The documentation for this struct was generated from the following file:

Gems/LyShine/Code/Source/UiTextComponentOffsetsSelector.h
