Method Detail

showRouterLayoutContent

default void showRouterLayoutContent(HasElement content)

Shows the content of the layout which is the router target component annotated with a @Route.

Note implementors should not care about old @Route content, since it's handled separately by removeRouterLayoutContent(HasElement) which by default simply removes the old content.

Parameters:

content - the content component or null if the layout content is to be cleared.

removeRouterLayoutContent

default void removeRouterLayoutContent(HasElement oldContent)

Removes content that should no longer be shown in this router layout. If showRouterLayoutContent(HasElement) was previously called with a non-null parameter, then this method will be called with the same parameter immediately before calling showRouterLayoutContent(HasElement) again.

By default, the old content is removed from its parent using Element.removeFromParent().

Parameters:

oldContent - the old content to remove, not null
