	OnClick  func()                  // Button
}

Field for your form (or form-aligned label sections, etc.)

The type of Form control to render is inferred based on bound variables and other configuration.

func (Field) Infer

func (field Field) Infer() Type

Infer the type if the field was of type Auto.

Returns the first Type inferred from the field by checking in this order:

- Frame if the field has a *Frame - Checkbox if there is a *BoolVariable - Selectbox if there are Options - Textbox if there is a *TextVariable - Text if there is a Label

May return Auto if none of the above and be ignored.

type Form

type Form struct {
	Supervisor *ui.Supervisor // Required for most useful forms
	Engine     render.Engine

	// For vertical forms.
	Vertical   bool
	LabelWidth int // size of left frame for labels.
	PadY       int // spacer between (vertical) forms
	PadX       int
}

Form configuration.

func (Form) Create

func (form Form) Create(into *ui.Frame, fields []Field)

Create the form field and populate it into the given Frame.

Renders the form vertically.

	Value     interface{}
	Label     string
	Separator bool
