widgets

type Event ¶

type Event uint8

I want to try and simplify event handling for widgets. Not sure this counts.

const (
	ButtonUp Event = iota
	ButtonDown
	ButtonLeft
	ButtonRight
	ButtonA
	ButtonB
	ButtonSelect
	ButtonStart
)

type Home ¶

type Home struct {
	// contains filtered or unexported fields
}

Home widget displaying our name and logo. Felt cute. Might delete later.

func NewHome(renderer *sdl.Renderer, size *sdl.Rect) *Home

func (h *Home) ProcessEvent(e Event) bool

func (w Home) SetNext(next Widget)

func (h *Home) Texture() *sdl.Texture

type Menu ¶

type Menu struct {
	// contains filtered or unexported fields
}

Menu widget displaying a list of potential choices, each of which should map to some kind of Action.

func NewMenu(r *sdl.Renderer, s *sdl.Rect, choices []MenuChoice) *Menu

func (m *Menu) Confirm()

func (m *Menu) Down()

func (m *Menu) ProcessEvent(e Event) bool

func (w Menu) SetNext(next Widget)

func (m *Menu) Texture() *sdl.Texture

func (m *Menu) Up()

type MenuChoice ¶

type MenuChoice struct {
	Text   string
	Action func()
}

MenuChoice groups a choice string with the corresponding action.

type Properties ¶

type Properties struct {
	Font      *ttf.Font
	TitleFont *ttf.Font

	BgColor sdl.Color
	FgColor sdl.Color

	Zoom int // Zoom factor for the GameBoy display. Used for outlines, margins.
}

Properties stores useful configuration variables to be passed to all widgets at creation time.

type Widget ¶

type Widget interface {
	ProcessEvent(Event) bool
	Texture() *sdl.Texture
}
