about button and tooltip in GTK_WINDOW_POPUP

["Cai Qiang" <caiqiang ustc edu>]

Hi, 
    I encounter below problem when using a GTK_WINDOW_POPUP type gtk_window(see the attached code): 
When I use GTK_WINDOW_TOPLEVEL，all work fine：when mouse on button, buuton will float; tooltip also will 
display; But in GTK_WINDOW_POPUP case, they don't work. 

Do I miss any setting procedure for POPUP type gtk_window? Or is there any method to let TOPLEVEL type 
gtk_window not shown in toolbar? 

Thanks a lot!
