connectGetChildPosition
fun connectGetChildPosition(connectFlags: <Error class: unknown class> = ConnectFlags(0u), handler: (widget: Widget, <Error class: unknown class>) -> Boolean): <Error class: unknown class>
Emitted to determine the position and size of any overlay child widgets.
A handler for this signal should fill @allocation with the desired position and size for @widget, relative to the 'main' child of @overlay.
The default handler for this signal uses the @widget's halign and valign properties to determine the position and gives the widget its natural size (except that an alignment of %GTK_ALIGN_FILL will cause the overlay to be full-width/height). If the main child is a GtkScrolledWindow, the overlays are placed relative to its contents.
Parameters
connectFlags
A combination of ConnectFlags
handler
the Callback to connect. Params: widget the child widget to position; allocation return location for the allocation. Returns true if the @allocation has been filled
