ui.VirtualList() *Element

VirtualList lays out and paints the visible children using the core's virtual list.

ChildChild(child any) *Element—

Child appends content and returns this element. Content can be an element, native node, scalar, accessor, or node-returning construction callback.

Child(child any) *Element

ソースを見る

ChildrenChildren(children ...any) *Element—

Children appends multiple children in order without replacing existing content. It also accepts []any, []*Element, and []*native.Node slices as arguments. Read the retained child nodes through element.Node.Children.

Children(children ...any) *Element

StyleStyle(style StyleBuilder) *Element—

Style merges a reusable style. Scalar accessors retain independent native bindings.

Style(style StyleBuilder) *Element

ソースを見る

OnClickOnClick(handler func()) *Element—

OnClick handles a click without an unused event parameter.

OnClick(handler func()) *Element

ソースを見る

RefRef(handler func(*native.Node)) *Element—

Ref exposes the native handle once at this point in the declaration chain.

Ref(handler func(*native.Node)) *Element
