The ::delete-event signal is emitted if a user requests that a toplevel window is closed. The default handler for this signal destroys the window. Connecting Widget.hideOnDelete to this signal will cause the window to be hidden instead, so that it can later be shown again without reconstructing it.

class Widget
bool delegate dlg
ConnectFlags connectFlags = cast(ConnectFlags)0

Return Value

Type: gulong

TRUE to stop other handlers from being invoked for the event. FALSE to propagate the event further.
