*TextField
sync.Mutex
// contains filtered or unexported fields
}
func NewInputField(fontSource *text.GoTextFaceSource, fontSize int, fontMutex *sync.Mutex) *InputField
NewInputField returns a new InputField. See type documentation for more info.
func (f *InputField) HandleKeyboardEvent(key ebiten.Key, r rune) (handled bool, err error)
HandleKeyboardEvent passes the provided key or rune to the Inputfield.
func (f *InputField) SetChangedFunc(changedFunc func(r rune) (accept bool))
SetChangedFunc sets a handler which is called when the text buffer is changed. The handler may return true to add the rune to the text buffer.
func (f *InputField) SetHandleKeyboard(handle bool)
