gtkDialogNewWithButtons
and other convenience
functions in GTK+ will sometimes call
gtkWindowSetTransientFor
on your behalf.gtkWindowSetTransientFor(object, parent = NULL)
object
parent
NULL
. [ allow-none ]NULL
for parent
unsets the current transient window.
On Windows, this function puts the child window on top of the parent,
much as the window manager would have done on X.
