Method Update

core/update.go:56–66

Update updates the widget and all of its children by running [WidgetBase.UpdateWidget] and [WidgetBase.Style] on each one, and triggering a new layout pass with [WidgetBase.NeedsLayout]. It is the main way that end users should trigger widget updates, and it is guaranteed to fully update a widget to

()

// call [WidgetBase.AsyncLock] and [WidgetBase.AsyncUnlock] before and
// after this, respectively.
func (wb *WidgetBase) Update() { //types:add
	if DebugSettings.UpdateTrace {
		fmt.Println("\tDebugSettings.UpdateTrace Update:", wb)
	}
	wb.WidgetWalkDown(func(cw Widget, cwb *WidgetBase) bool {
		cwb.UpdateWidget()
		cw.Style()
		return tree.Continue
	})
	wb.NeedsLayout()
}

// UpdateRender is the same as [WidgetBase.Update], except that it calls
// [WidgetBase.NeedsRender] instead of [WidgetBase.NeedsLayout].
