Method

GtkWindowset_transient_for

Declaration [src] 

void
gtk_window_set_transient_for (
  GtkWindow* window,
  GtkWindow* parent
)

Description [src]

Dialog windows should be set transient for the main application window they were spawned from. This allows [window managers][gtk-X11-arch] to e.g. keep the dialog on top of the main window, or center the dialog over the main window. gtk_dialog_new_with_buttons() and other convenience functions in GTK+ will sometimes call gtk_window_set_transient_for() on your behalf.

Passing NULL for parent unsets the current transient window.

On Wayland, this function can also be used to attach a new

GTK_WINDOW_POPUP to a #GTK_WINDOW_TOPLEVEL parent already mapped

on screen so that the #GTK_WINDOW_POPUP will be created as a subsurface-based window #GDK_WINDOW_SUBSURFACE which can be positioned at will relatively to the #GTK_WINDOW_TOPLEVEL surface.

On Windows, this function puts the child window on top of the parent, much as the window manager would have done on X.

Sets propertyGtk.Window:transient-for

Parameters

parent

Type: GtkWindow

Parent window, or NULL.

The argument can be NULL.
