1. Trapping menu clicks in GTK2
Irv, or anyone else with GTK2 experience:
How do you trap menu selections? I tried applying the code for the quit
button from button.exu to a File-->Quit menu choice, but it didn't work. Any
help is as always appreciated.

Here's a clip from a working program.
bar and filemenu are defined as atoms, fileitem is an object, since
it grows as the menu items are added.
the db: items are, of course, from "include db_file.e as db" , ,
where db_file.e has handlers to connect to database.e functions.
For example: db:create references a global constant 'create' in db_file.e ...
function Create()
-- call db_create()
return NULL
end function
global constant create = call_back(routine_id("Create"))
So, then you can hook that call into the menu item as shown below:
bar = menubar()
pack(panel,bar,0,0,0)
filemenu = menuitem("_File")
fileitem = choice("gtk-new",db:create,0)
fileitem &= choice("gtk-open",db:open,0)
fileitem &= choice("gtk-close",db:close,0)
separator()
fileitem &= choice("gtk-quit",quit,win)
set_submenu(filemenu)
setMenuItems(fileitem,{1,1,0})
The zero passed as the last parameter is usually unused, but whatever is
there will be passed to the function being called, so you could pass
a value if it would help.
Perhaps if you had a 'help' function, you could declare several menu
items which all called the same routine, but passed a different number,
to show different bits of information.
Hope that helps,
Irv

Err. please ignore the line:
setMenuItems(fileitem,{1,1,0})
That calls a routine earlier in the program, not a part of EuGTK.
Sorry if it was confusing.

Hi Michael,
I'll paste some code from a program i made using Irv's GTK2 Wrappers, i hope it
helps:
function ShowHarvText(atom ctl, atom data)
end function
constant show_harvtext = call_back(routine_id("ShowHarvText"))
hout3 = button("Calcular")
when(hout3,"clicked",show_harvtext,0)
Best Regards,

This is correct for buttons, and most other controls, but not for menu
items, as they handle their own signals. See my previous example for menus.
Rob: when we reply and "quote original text", it copies the html markup
as well. Is there a way around this?

Oops: I guess that is a non-issue. The html only shows up in the
textarea when we quote, once it gets to the forum, it looks ok.

My mail client received your previous message _with_ its HTML tags. 
(This one too, but this is no real HTML here.)
