Linear layout

A linear layout is a list of Views that are placed one after the other along the horizontal or vertical axis.

The main flow when working with a LinearLayout is the following:

• Create the layout: you need to choose which orientation you want your views arranged in
• Optionally, set secondary alignment
• Add views you want to arrange
• Call arrange to finalize view placement
• Align the returned ViewGroup to where you want it to be displayed
• Call draw to display the views

Orientation

When constructing a LinearLayout object, you need to choose an orientation along which the views will be arranged. This can either be horizontal or vertical.

Examples:

Create a LinearLayout with two pieces of text, where one is below the other:

let text_style = TextStyleBuilder::new(Font6x8)
                        .text_color(BinaryColor::On)
                        .build();

let _ = LinearLayout::vertical()
            .add_view(Text::new("Hello,", Point::zero()).into_styled(text_style))
            .add_view(Text::new("World!", Point::zero()).into_styled(text_style))
            .arrange();

Secondary alignment

Secondary alignment means the alignment on the "other" axis:

• horizontal alignment in vertical linear layouts
• vertical alignment in horizontal linear layouts

By default, the secondary alignments are the following:

• Horizontal orientation: vertical::Bottom
• Vertical orientation: horizontal::Left

Structs

Horizontal	Horizontal layout direction
LinearLayout	LinearLayout
Vertical	Vertical layout direction

Traits
