func CalculateTopMiddleBottom(w IWidget, size gowid.IRenderSize) (int, int, int)

func DownLines 

func DownLines(w IWidget, size gowid.IRenderSize, doPage bool, app gowid.IApp) bool

Return true if done

func MakeText 

func MakeText(w IWidget) text.IWidget

func Render 

func Render(w IWidget, size gowid.IRenderSize, focus gowid.Selector, app gowid.IApp) gowid.ICanvas

Types

type Caption 

type Caption struct{}

type Cursor 

type Cursor struct{}

type IEdit 

type IEdit interface {
	text.ISimple
	IMask
	text.ICursor
	Caption() string
	MakeText() text.IWidget
}

IEdit is an interface to be implemented by a text editing widget. A suitable implementation will be able to defer to RenderEdit() in its Render() function.

type IMask 

type IMask interface {
	UseMask() bool
	MaskChr() rune
}

type IWidget 

type IWidget interface {
	IEdit
	text.IChrAt
	LinesFromTop() int
	SetLinesFromTop(int, gowid.IApp)
	UpLines(size gowid.IRenderSize, doPage bool, app gowid.IApp) bool
	DownLines(size gowid.IRenderSize, doPage bool, app gowid.IApp) bool
}

type Mask 

type Mask struct {
	Chr    rune
	Enable bool
}

func DisabledMask 

func DisabledMask() Mask

func MakeMask 

func MakeMask(chr rune) Mask

func (Mask) MaskChr 

func (m Mask) MaskChr() rune

func (Mask) UseMask 

func (m Mask) UseMask() bool

type Options 

type Options struct {
	Caption string
	Text    string
	Mask    IMask
}

type Text 

type Text struct{}

For callback registration

type Widget 

type Widget struct {
	IMask

	Callbacks *gowid.Callbacks
	gowid.IsSelectable
	// contains filtered or unexported fields
}

func New 

func New(args ...Options) *Widget

func (*Widget) CalculateTopMiddleBottom 

func (w *Widget) CalculateTopMiddleBottom(size gowid.IRenderSize) (int, int, int)

func (*Widget) Caption 

func (w *Widget) Caption() string

func (*Widget) ChrAt added in v1.1.0 

func (w *Widget) ChrAt(i int) rune

TODO - this isn't ideal- if called in a loop, it would be quadratic.

func (*Widget) CursorEnabled 

func (w *Widget) CursorEnabled() bool

func (*Widget) CursorPos 

func (w *Widget) CursorPos() int

TODO - weird that you could call set to 0, then get and it would be > 0...

func (*Widget) DownLines 

func (w *Widget) DownLines(size gowid.IRenderSize, doPage bool, app gowid.IApp) bool

func (*Widget) LinesFromTop 

func (w *Widget) LinesFromTop() int

func (*Widget) MakeText 

func (w *Widget) MakeText() text.IWidget

func (*Widget) OnCaptionSet 

func (w *Widget) OnCaptionSet(cb gowid.IWidgetChangedCallback)

func (*Widget) OnCursorPosSet 

func (w *Widget) OnCursorPosSet(cb gowid.IWidgetChangedCallback)

func (*Widget) OnTextSet 

func (w *Widget) OnTextSet(cb gowid.IWidgetChangedCallback)

func (*Widget) Read 

func (w *Widget) Read(p []byte) (n int, err error)

Set array from widget content

func (*Widget) RemoveOnCaptionSet 

func (w *Widget) RemoveOnCaptionSet(cb gowid.IIdentity)

func (*Widget) RemoveOnCursorPosSet 

func (w *Widget) RemoveOnCursorPosSet(cb gowid.IIdentity)

func (*Widget) RemoveOnTextSet 

func (w *Widget) RemoveOnTextSet(cb gowid.IIdentity)

func (*Widget) Render 

func (w *Widget) Render(size gowid.IRenderSize, focus gowid.Selector, app gowid.IApp) gowid.ICanvas

func (*Widget) RenderSize 

func (w *Widget) RenderSize(size gowid.IRenderSize, focus gowid.Selector, app gowid.IApp) gowid.IRenderBox

func (*Widget) SetCaption 

func (w *Widget) SetCaption(text string, app gowid.IApp)

func (*Widget) SetCursorDisabled 

func (w *Widget) SetCursorDisabled()

func (*Widget) SetCursorPos 

func (w *Widget) SetCursorPos(pos int, app gowid.IApp)

func (*Widget) SetLinesFromTop 

func (w *Widget) SetLinesFromTop(l int, app gowid.IApp)

func (*Widget) SetText 

func (w *Widget) SetText(text string, app gowid.IApp)

func (*Widget) String 

func (w *Widget) String() string

func (*Widget) Text 

func (w *Widget) Text() string

func (*Widget) UpLines 

func (w *Widget) UpLines(size gowid.IRenderSize, doPage bool, app gowid.IApp) bool

func (*Widget) UserInput 

func (w *Widget) UserInput(ev interface{}, size gowid.IRenderSize, focus gowid.Selector, app gowid.IApp) bool

type Writer 

type Writer struct {
	*Widget
	gowid.IApp
}

Writer embeds an EditWidget and provides the io.Writer interface. An gowid.IApp needs to be provided too because the widget's SetText() function requires it in order to issue callbacks when the text changes.

func (*Writer) Write 

func (w *Writer) Write(p []byte) (n int, err error)

Set content from array
