By taylorchu:

I was thinking about dialog. but hime-setup is not a "dialog", it is a utility to setup hime, create words, and import data. seeing the meaning of this program, it is quite reasonable to think it is a "utility" rather than a "dialog".

besides, according to your link (thanks for the link), " _NET_WM_WINDOW_TYPE_UTILITY indicates a small persistent utility window, such as a palette or toolbox. It is distinct from type TOOLBAR because it does not correspond to a toolbar torn off from the main application. It's distinct from type DIALOG because it isn't a transient dialog, the user will probably keep it open while they're working. Windows of this type may set the WM_TRANSIENT_FOR hint indicating the main application window." it really should not be a dialog.

for the two reasons, utility should be the best choice.
