Functions

func LogHint

func LogHint(reason string)

LogHint reports a developer hint that should be followed to improve their app. This does nothing unless the "hints" build flag is used.

func ScaleInt

func ScaleInt(c fyne.Canvas, v int) int

ScaleInt converts a fyne coordinate in the given canvas to a screen coordinate

func UnscaleInt

func UnscaleInt(c fyne.Canvas, v int) int

UnscaleInt converts a screen coordinate for a given canvas to a fyne coordinate

Types

type InMemoryPreferences

type InMemoryPreferences struct {
	OnChange func()
	// contains filtered or unexported fields
}

InMemoryPreferences provides an implementation of the fyne.Preferences API that is stored in memory.

func NewInMemoryPreferences
