gtk:window-destroy-with-parent (object)

object -- a gtk:window widget
setting -- a boolean whether to destroy the window with its transient parent

Accessor of the destroy-with-parent slot of the gtk:window class. The gtk:window-destroy-with-parent function returns whether the window will be destroyed with its transient parent. The (setf gtk:window-destroy-with-parent) function sets whether to destroy the window with its transient parent. If the setting argument is true, then destroying the transient parent of the window will also destroy the window itself.

This is useful for dialogs that should not persist beyond the lifetime of the main window they are associated with.
