connectPageDetached
fun connectPageDetached(connectFlags: <Error class: unknown class> = ConnectFlags(0u), handler: (page: TabPage, position: Int) -> Unit): <Error class: unknown class>
Emitted when a page has been removed or transferred to another view.
A typical reason to connect to this signal would be to disconnect signal handlers connected in the signal@TabView::page-attached handler.
It is important not to try and destroy the page child in the handler of this function as the child might merely be moved to another window; use child dispose handler for that or do it in sync with your method@TabView.close_page_finish calls.
Parameters
connectFlags
A combination of ConnectFlags
handler
the Callback to connect. Params: page a page of @self; position the position of the removed page, starting from 0
