Overview

Package mtldriver provides a Metal driver for accessing a screen.

At this time, the Metal API is used only to present the final pixels to the screen. All rendering is performed on the CPU via the image/draw algorithms. Future work is to use mtl.Buffer, mtl.Texture, etc., and do more of the rendering work on the GPU.

Functions

func Main

func Main(f func(screen.Screen))

Main is called by the program's main function to run the graphical application.

It calls f on the Screen, possibly in a separate goroutine, as some OS- specific libraries require being on 'the main thread'. It returns when f returns.

Types

type BGRA

type BGRA = image.RGBA

type Window

type Window struct {
	event.Deque
	// contains filtered or unexported fields
}

Window implements screen.Window.

func (*Window) Draw

func (w *Window) Draw(src2dst f64.Aff3, src screen.Texture, sr image.Rectangle, op draw.Op)

func (*Window) GetCursorPosition

func (w *Window) GetCursorPosition() (x, y float64)

func (*Window) HideCursor

func (w *Window) HideCursor() error

func (*Window) MoveWindow

func (w *Window) MoveWindow(x, y, width, height int) error

func (*Window) NextEvent

func (w *Window) NextEvent() interface{}

func (*Window) Publish

func (w *Window) Publish()

func (*Window) Release

func (w *Window) Release()

func (*Window) Scale

func (w *Window) Scale(dr image.Rectangle, src screen.Texture, sr image.Rectangle, op draw.Op)

func (*Window) SetBorderless

func (w *Window) SetBorderless(borderless bool) error

func (*Window) SetFullScreen

func (w *Window) SetFullScreen(full bool) error
