Package su.onno.ui.divkit

Class PageDivBuilder

java.lang.Object

su.onno.ui.divkit.PageDivBuilder

public final class PageDivBuilder
extends Object

Renders an authored Page to DivKit content: a header, then a recursive PageDivBuilder.Region tree — each region is a widget grid + freeform PageComponent blocks + nested PageDivBuilder.Rows of PageDivBuilder.Columns, so a page can compose an arbitrary column layout (and a right rail is just the common two-column case). Built from native DivKit primitives (custom blocks become div-custom), so it renders on every official SDK.

 Function<PageWidgetDescriptor,Boolean> canWrite,

Flat render with an optional right rail. asideWidgets/asideComponents compose a narrow column beside the main content on desktop, stacked below it on mobile (columns == 1).

build

 String subtitle,
 boolean header,
 PageDivBuilder.Region main,
 PageDivBuilder.Region aside,
 boolean desktop,
 Function<PageWidgetDescriptor,String> values,
 Function<PageWidgetDescriptor,Boolean> canWrite,
 Palette p)

Render a page from its region tree. desktop controls layout direction: rows lay their columns out horizontally and grids use their column count; on mobile everything stacks. An aside region, when present, renders as a fixed-width rail to the right of main.
