---

childResized()

protected childResized(_child): void;

Defined in: src/ui/Widget.ts:108

A child widget's box changed size by itself (a Label given a longer text). A widget that places a child by its size (a Button centring its content) lays it out again here; the default does nothing, so a Stack still waits for its layout() and a change does not ripple up through every container.

Parameters

Parameter	Type
_child	Widget

Returns

void

Inherited from

Widget.childResized

---

makeInteractive()

protected makeInteractive(): void;

Defined in: src/ui/Widget.ts:98

Hit-tested by Pixi, and every press on it is kept from the world. A widget whose drawing has gaps (a scroll view, an empty panel) also sets a hitArea over its box, so a press between its pieces is not the world's.

Returns

void

Inherited from

Widget.makeInteractive

---

navigate()

navigate(_dir): boolean;

Defined in: src/ui/Widget.ts:85

A direction pressed while focused; true when the widget used it (a slider stepping) so focus stays.

Parameters

Parameter	Type
_dir	NavDirection

Returns

boolean

Inherited from

Widget.navigate

---

notifyResized()

protected notifyResized(): void;

Defined in: src/ui/Widget.ts:111

Tells the parent widget this one's box changed size by itself.

Returns

void

Inherited from

Widget.notifyResized

---

place()

place(x, y): this;

Defined in: src/ui/Widget.ts:68

Moves it, on whole pixels under a pixel-perfect root.

Parameters

Parameter	Type
x	number
y	number

Returns

this

Inherited from

Widget.place

---

redraw()

protected redraw(): void;

Defined in: src/ui/Toggle.ts:61

Draws the current size and state.

Returns

void

Overrides

Widget.redraw

---

resize()

resize(width, height): this;

Defined in: src/ui/Widget.ts:59

Resizes the layout box (whole pixels under a pixel-perfect root) and redraws.

Parameters

Parameter	Type

height	number

Returns

this

Widget.resize

---

set()

set(value, silent?): this;

Defined in: src/ui/Toggle.ts:49

Sets it; silent skips onChange (mirroring a stored setting into the widget).

Parameters

Parameter	Type	Default value
value	boolean	undefined
silent	boolean	false

Returns

this

---

setFocused()

setFocused(v): void;

Defined in: src/ui/Widget.ts:52
