problems creating windows

[Gregory Babusiaux <gbabusia ulb ac be>]

hi i got a problem in an application i'm trying to develop.

I've created a new window (the main window) with the command

window=gtk_window_new(GTK_WINDOW_TOPLEVEL);

by pressing on a button , i'd like to create a child window. So that in the callback function i 'd like to create the child window. But i don't know to create the child window

window=gtk_window_new(GTK_WINDOW_CHILDLEVEL) doesn't work!!

Can anyone help me???

thanks a lot for reading
