# GIOWrap

An experimental wrapper package for the Gio immediate mode GUI, designed to reduce
boilerplate.

The basic concept is to define a `Context` type that contains the Gio variables
required for layout and drawing. `Context` contains a pointer to `app.Window` and
`ui.Ops` so that, once layout is complete, you can call `Context.Draw()` to draw
your objects in your window.

The following types and functions are defined in order to transform a `Context`
variable during layout:

```go
type Layout func(Context) Context

type Widget interface {
	Layout(Context) Context
}

func LayoutWithContext(ctx Context, ws ...Widget) Context {
	for _, w := range ws {
		ctx = w.Layout(ctx)
	}
	return ctx
}

type WidgetCombinator func(...Widget) Widget

type Enclosure interface {
	Begin(Context) Context
	End(Context) Context
}

func Enclose(e Enclosure, w ...Widget) Widget { ... }
```
