Hi,
I know that I can not directly add widget to clist.
I have tried it and is working but I have some problems.
I am adding clist in scrollwindow.
scrollwindow in vbox.
entry in vbox
vbox in toplevel window.
On double click of clist I am finding x, y, width and height of cell
clicked.
then calling
gdk_window_reparent( entry->window, clist->window, x, y );
then entry's gdkwindow appears in clist, you can edit it.
But I am not able to remove the empty space at bottom of the vbox,
created because of reparenting of gdkwindow of entry.
my source code is here

Hi, The CList doesn't support child widgets in the rows. You have to do something like put an entry next to the clist which is used to edit the currently-selected clist row. Havoc
