Macro kas::margins

margins!() { /* proc-macro */ }

Expand description

Make a margin-adjustment widget wrapper

This is a small wrapper which adjusts the margins of its contents.

Example

let a = kas::margins!(1.0 em, "abc");
let b = kas::margins!(vert = none, "abc");

Syntax

The macro takes one of two forms:

Margins:
   margins! ( MarginSpec , Layout )
   margins! ( MarginDirection = MarginSpec , Layout )

MarginDirection :
   horiz | horizontal | vert | vertical | left | right | top | bottom

MarginSpec :
   ( LitFloat px ) | ( LitFloat em ) | none | inner | tiny | small | large | text

MarginSpec	Description (guide size; theme-specified sizes may vary and may not scale linearly)
`none`	No margin (`0px`)
`inner`	A very tiny theme-specified margin sometimes used to draw selection outlines (`1px`)
`tiny`	A very small theme-specified margin (`2px`)
`small`	A small theme-specified margin (`4px`)
`large`	A large theme-specified margin (`7px`)
`text`	Text-specific margins; often asymmetric
LitFloat `em` (e.g. `1.2 em`)	Using the typographic unit Em (`1Em` is the text height, excluding ascender and descender)
LitFloat `px` (e.g. `5.0 px`)	Using virtual pixels (affected by the scale factor)
