# 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 { ... }
|
|
```
