[gtkmm] i can delete toolbar ButtonElements...

[cedric <cedric probesys com>]

Hello,
I m still working on my modular application and once more, i ve 
encountered a problem that i don t manage to solve. this time, it 
concerns the toolbar: in fact, in my menubar, i can select one module 
among several ones. this provoques (or it is mean to) the toolbar to 
change, to be in relation with the actual selected module.
i ve managed to add buttons to the toolbar, it i ve read the gtkmm2.2 
doc (i m not developping under gtkmm2.4) and didn t understand how to 
delete buttons. :-[ i suppose i have to use one of these methods:

virtual void  Gtk::Toolbar_Helpers::ToolList::erase (iterator start, 
iterator stop)
iterator  Gtk::Toolbar_Helpers::ToolList::erase (iterator)
virtual void  Gtk::Toolbar_Helpers::ToolList::remove (Widget& widget)

i ve tried all of them: to get an iterator, i ve tried to use the two 
Gtk::Toolbar_Helpers::ToolList::find methods without any success.
i ve tried the above remove method with a ButtonElem parameter (my 
toolbar contains nothing else that ButtonElems), but no more success...

i know my problem may seem stupid for you, but i m not very skilled in 
C++ and without any comments, the API is a bit obscur for me sometimes 
(like this time), especially for the templates! Thanks for your 
explainations! ;-)

ps: Matthew Walton, once (1 or 2 weeks ago ;-D ) you told me than there 
were a better way to delete several lines of a ListStore than the way i 
tried to use. i ve no other idea, so could you tell me how to do it in a 
"clean" way? my purpose is not to recopy some code, but to learn! ;-) 
thanks too!
