[jh_wang2004 <jh_wang2004 163 com>]

hi all:
In my app program initialization, it connects database, initializes SDL video channel,etc .
these actions have been done before gtk mainloop,
i want to display these  initial message to user, and destroy the widget after initialization has been done, 
which widget shall i use?
I try to use gtkdialog without button, but it seems prevents theFollow-upinstructions，for that wait for 
response.
                                                                                                              
                           Regards
