GdkWindowdeiconify

Attempt to deiconify (unminimize) window. On X11 the window manager may choose to ignore the request to deiconify. When using GTK+, use gtk_window_deiconify() instead of the GdkWindow variant. Or better yet, you probably want to use gtk_window_present_with_time(), which raises the window, focuses it, unminimizes it, and puts it on the current desktop.
